Why motorway speed limit is still 70 mph? - movilogo
I know the question apparently may sound daft.

There are several organizations (including some motoring organisations and Conservative Party) are advocating for the limit to raise 80 mph at least, over many years. Many studies have also been in favour of revised higher limit.

So, what is the fundamental problem which prevents limit being raised?

If most people want something but it is still can't be implemented, it usually means there are fewer people who are against it - but they are actually far powerful than millions of ordinary citizens. So, govt. is more interested in their demand than rest of us.

For example, everyone is seemed to against immigration - but govt. is reluctant to impose any control on migrants. Simply because most powerful industrialists are in favour or immigration since it supplies them with cheap labour thus increasing their profit.

Similarly, there is "conspiracy theory" that Congestion Charge is actually welcomed by city millionaires - as it makes travelling through London streets much faster in their Rolls, Aston or Ferraris.

Set it to 80 and use SPECS to catch anyone doing 90+. That way we get the benefits, I don't feel nervous about doing 80mph on an empty motorway in case there's a camera van on a bridge ahead, and the police make a bit of spare change from persistent speeders.

It can only be reduced. The current hype about global warming and emissions will see to that.

If the national speed limit were a rigidly `policed` 55mph, I imagine fuel savings would be enormous.
I reckon its got to come to that sooner or later.
Its just surprising that while the `Green` focus is on getting power from `windmills`, big luxo-barges blast along at 80MPH plus guzzling unnecessary amounts of fuel on the motorways.

It's not true that 'most' people want the limit raised. It may be that a majority of the people you discuss it with would like it to be so, but you can't extrapolate that to the general population. If it was as clear cut, a single issue party could stand for election, change the law and then stand down. The fact that no-one has done that shows how important this issue is to most people.
For example everyone is seemed to against immigration - but govt. is reluctant to impose
any control on migrants. Simply because most powerful industrialists are in favour or immigration since


Again, it's not a clear majority. We have no power to control immigration from the EU anyway - the Schengen agreement gives all Europeans (with some limitations on citizens of recent accesion countries) the right to live or work anywhere within the union. The reason that so many mainland Europeans come here (working for a pan-European business, this includes many of my colleagues) is that our tax rates are very low compared to our neighbours. Colleagues from the Netherlands and Sweden say that working here is like getting a 30% pay rise.

I digress - I think if you put it to the vote, the pro, anti and ambivalent views on immigration balance out, with the majority in the ambivalent group.

After reading your post, I did have a look there

Tax rates outside Europe seemed quite low! This page mentioned the min to max range of tax on countries. So, it is bit difficult to see why you say that UK tax rate is lower than our EU neighbors. I know Scandinavian countries are high tax payers. But not sure if we can say the same for France/Germany/Benelux etc.

They (the Dutch, Norwegians and probably other European Countries) get fabulous redundancy benefits, that's if you can prise them out of their job. The norm is to fire a Brit and transfer the job.

Well, I specifically said Europe. If you look at those bands, the personal rates tend to go upto around 50% (60% in Denmark / Sweden). My colleagues would be paying the highest rates in their countries and our 40% is a big saving to them.

They even save money on driving (petrol in France is about 8% cheaper, but try paying £80 a month in motorway tolls to get in to Paris every day).

Sales tax tends to be higher too in Europe, 20% is typical.

Do our EU neighbours pay council tax?

Yes, there is often some form of local taxation. My colleague in Stockholm tells me that he actually gets to keep about 20% of his gross pay. Strangely, the Scandinavian nations, as well as paying the highest taxes in the world, are also the most content.

Citizens from the 'new' Eastern European EU countries can only work in UK, Ireland and (I think??) Sweden. They are not allowed to work in Germany for 7 years - although some get work permits and do. I know this because I have Polish relatives and their only real option (for low- or no-skills) is UK or Ireland. Plus there are agencies in Poland representing British companies touting for staff, one of the bus companys actually has a recruitment office in Warsaw. My cousin lives in SW Poland and in some of the small town half the menfolk are in England! The 'official' figure is the tip of the iceberg. They are all good workers though, and not greedy or troublemakers, so employers cant get enough of them, cant blame them.

Speed limit is not that much of an issue with me. 70 or 80, does it matter? If I am on a longish journey then making steady progress is more important than max speed I can reach. No point in trucking along at 80 if I then hit 10mph crawl for half an hour. On the clear bits 80 seems to be the de facto limit anyway.

The numbers are still tiny though. Even if five times as many people committed suicide in Sweden as here, that's a tiny fraction of the population.

The average citizen, when questioned about levels of contentment, is happier in the Nordic countries than in most other places. The average citizen isn't planning suicide.

A similar statistical misinterpretation relates to the UK motoring fatality stats. At a top level we look good compared to other European countries, but we have a high child death rate. One doesn't cancel out the other, they're individual measures.
Why motorway speed limit is still 70 mph? - Brian Tryzers
Would this new 80mph limit apply even on the congested motorway that makes up most of my journey to and from work? And if so, how would it help? It seems to me that not many drivers stick firmly to 70mph 'because that's the law' - and those that do probably know the bit about keeping left unless overtaking too, so they stay out of the way. (Those that regard a truck half a mile ahead as reason enough to stay in the middle lane are, of course, excluded from this. So is the bloke in the silver Lexus yesterday, who pulled into the empty nearside lane at my approach, let me pass, then carefully mirror-signal-manoeuvred his way back into the middle.)
The rest generally drive as fast as they can anyway because - on my motorway at least - there is next to no enforcement. And because they regard the driver in front as an idiot who's blocking their way, they drive too fast and too close and resort to extraordinary tricks to make minute amounts of progress.

The analogy occurred to me the other day, as we were evacuating the seven-storey building I work in after the fire alarm went off. This meant walking down four (for me) flights of stairs, in company with people from the floors above mine, and being joined by others from the floor below. There was no jostling, no me-firsting, and a perfect merge-in-turn etiquette was observed as people joined from lower floors. It took me about three times as long as it does when I go downstairs on my own for a cup of coffee, but we all got out and were subsequently praised by the building services people for such an orderly evacuation.
Ironically, I wonder how many of my colleagues behaved with equal courtesy, decorum and public spirit two hours later as they drove home.

I may have wandered from the topic a little, but my point is that the speed limit is barely relevant to the safe and effective use of the modern British motorway.

Quite honestly, with traffic getting so bad on occasion, before raising the limit, how about reducing congestion first which has over most journeys, a greater impact on the journey time than doing an extra 10 mph.
Having had to regularly travel the A14 it wasnt really possible to maintain 80 mph for any length of time as the hold ups, due to traffic volume had a greater effect and sorting this would help in reducing my travel time far more.

Well, there were unlimited (effectively) at the introduction of motorways. Unfortunately, experience soon showed that owing to the preponderance of numpties on our roads, that limits would be required. The reason we can't drive properly is probably correlates highly with the reason we can't drink properly either - Anglo-Saxon mixed with Norman French (or Scandinavian in other words) is a ghastly mixture of hubris & inferiority complex that makes any unregulated activity soon resemble a medieval football match. Sadly, we need rules in copious abundance to operate & co-operate in this country.

"how about reducing congestion first"

That should be one of the effects of raising (or better still, removing) the limit. The early birds would get to work that much sooner, reducing the volume on the road as others join in. Bunching at 80-ish would disappear and overall progress would improve. The accident rate might even go down as people watch the road instead of their speedometers.

IIRC, the original 70-limit was meant to be a temporary measure anyway! Mind you, so was income tax...

Why motorway speed limit is still 70 mph? - Billy Whizz
>The early birds would get to work that much sooner.
In fact what will happen is that the early birds will leave 10/ 20/ 30 minutes later and bunching would still take place but at 90mph. The accident rate will go up as the longer braking distances required will be compromised. The injuries will be more severe due to higher kinetic energy (V squared)

The reason I personally think the limit will not change is that the current situation works well enough on the congested roads of the UK. It is a good balance between safety and efficiency. The only place I can think of where one can reasonably justify a blanket increase is on the A74(M) north of Carlisle.

Don't quite follow that - congestion is surely due to the number of cars out on the roads, so just increasing the limit won't get rid of it as the rest of us who drive at less than 80 will still want to overtake others and the fast vehicles will still bunch behind us....

A constant lower limit would reduce journey times on busy motorways much more than raising the limit, surely?

I would also agree with another poster that with the amount of traffic we have on the motorways one of the few places you could increase the limit and actually be able to drive at it for any distance without slowing down would be the M74 norh of Carlisle, though the section south to Kendal junction isn't that bad either!

"how about reducing congestion first"

>>

That's a fallacy. If vehicles are moving faster then they need a greater distance between them. The effect of raising a speed limit is to reduce a road's capacity - the effect being most noticeable as the road reaches capacity.

At 70MPH in good conditions, braking distance is 315 feet. At 90 MPH it's nearly double. Yet the increase in throughput from driving at 90MPH is only just under 30%. So the effect is to almost double the space taken by each vehicle whilst reducing the time the vehicle is on that stretch of road by a much smaller amount. The net result is an increase in congestion.

That's one of the reasons behind the temporary limits on the M25.
Why motorway speed limit is still 70 mph? - Boggy
Bear in mind that the 70 limit was plenty fast enough when it was first introduced, in fact that was probably considered excessively fast in the days when everything was black and white. Modern cars with their airbags, bigger tyres, traction control, sound insulation and ABS etc are far more capable at cruising safely at higher speeds and are far more comfortable and quiet than say a 1960s Ford Anglia on its skinny tyres. I sometimes don't realise how fast I'm going on a motorway until SWMBO glances at the speedo and reminds me to slow down a bit!

70mph? On my last run from Newcastle to Berkshire and back I would have been happy to average that. What with huge long 50mph limits for roadworks (with the invisible workforce!) and generally rubbish roads (A1) I gave up trying to use cruise control.

Setting the limit any higher seems pointless to me - never mind all this C02 rubbish, its just the amount of cars on the road that seem to defy it.

What also concerns me is, when you're bowling along at the new legal limit of,say, 100mph and the obligatory truck pulls in front of you with no warning at 56mph you're really going to test out your NCAP 5 star rating....

Spent a lot of time driving across Germany to Austria. Without repeating previous threads, in general what you say is true. And even the older and younger drivers seem comfortable driving at higher speeds - not so many of the sunday afternoon drivers bimbling along at obstructive speeds. They do however exist, I can assure you! In general, I'd say most drivers seem to be more aware of what's going on around them, which is key when traffic is travelling at generally higher speeds - on some stretches of autobahn, I've been in the slow lane at 100mph......

And with regard to the main thread, 70mph is IMHO too low - my car is more economical at 80 than 70, and I doubt whether I'm alone....

I guess it's all to do with the engine being at the most efficient revs - maximum torque? 80mph in my car is around 2700 rpm (Saab 9-5 Aero estate auto, with torque converter lockup at 55mph).

I can also confirm that extended cruising at 100-110mph reduces the fuel consumption from 34mpg to 30mpg ;-)

Not necessarily. By your logic, there would be no difference in fuel consumption if the car was driven the same distance at 50mph in third, fourth or fifth gears - so clearly there is more than just wind resistance to take into account. Factors such as engine revs, given different levels of efficiency at different revs, will impact on the resultant fuel consumption.

With regard to consistency, I have satnav and can confirm that the speedo reading is consistent at around 5% fast. In addition, I have covered the same routes a number of times with the same results, and by the law of averages the weather conditions etc. will be fairly comparable. The roads I use have been a mixture of UK and european motorways, plus some A-road sections. The 400-mile return journey to Swansea at least 9 times a year is a good consisetnt test - clearly the welsh section is always wet :-)

Movilogo - Only for 2 days a couple of years ago, but the lane discipline was impressive.

On the other hand, some time ago I was in a taxi heading for Stuttgart airport on a dual carriageway limited to { I think } 120 or 130 km/hr, but it led directly on to the start of a full autobahn. The jockeying for "grid" position in the last couple of km of the dual carriageway really was something to behold. No speeding, just foot-to-the-floor as the open-limit sign was reached.

I have seen in a TV programme on the German autobahns that part of the driver testing is to prove that you are safe up to 200 km/hr. The driving school interviewee commented that they start pupils off at 130 and build up from there. Maybe that amount of training explains why the cost of getting a full German licence was quoted as 1500 euros, assuming first-time pass.
Why motorway speed limit is still 70 mph? - Dr_Duffy
I have driven in Germany several times, mostly in connection with my work.
I was surprised that the majority of autobahn is actually speed-restricted. I was told by German colleagues that well under half of the network is derestricted (around only 30% I recall). It is only the relatively quieter section of road that are derestricted. The speed limited sections can have quite low limits (100kph is common, and lower than that on many sections that I encountered). There is in any event a widely promoted 'advisory' maximum of 130kph and this is what a lot of drivers seemed to stick to. The number of cars travelling at very high speeds (100+mph) seemed very few.
We have, on the average, motorways which are much more congested than the German autobahns and 70mph (when achievable!) seems an appropriate limit given that a "+10%" rule is widely applied! Increasing the speed limit by 10mph would not make any significant difference to most people's journey times, but I supposed its a good political scoring point for the Tories.
Why motorway speed limit is still 70 mph? - audi dave

I passed through Germany twice, several years ago. Driving standards similar to the ones here, with plenty of mimsers and those infuriating people who pull out into the overtaking lane and then SLOW DOWN to inch past the other traffic.

However, very fast drivers often quite pushy and rude, coming up behind cars obviously going flat out and turning on main beams and foghorns... leave it out Hans, really.

What I noticed often though was trains of cars tailgating each other in the overtaking lane at well over 100mph, up to 130, even in wet conditions. Struck me as very dangerous, and I did see one mile-long shunt still steaming in (fortunately) the other carriageway.
Why motorway speed limit is still 70 mph? - b308
I've been across there every year for the past 10 years, usually driving at least 1500 miles in Germany mostly on Autobahns and found it so much more relaxing over there with very few "pushy" types and very good lane discipline.

You have to be very careful when overtaking on the derestriced bit in that even when travelling at 90/100mph you can have plenty doing 150+ who can get a little shirty if you don't judge your move right - I always double or even triple check before pulling out as they catch you up quickly at that speed - I do wonder if that what had happened above?

I've never had someone come up behind me with lights and horns - yes they do get close but they use their left hand indicator on to signal that they want through, and if they can see you are overtaking they don't push it... I've found using the same method to overtake when I needed to also works a treat...

Also they have far more stretches of Autobahn where HGVs are limited to the inside lane, though with some of the hills and not as much three lane stretches as us I can understnd why!

Having spent the last 3 weeks on the German autobahn, and often in France...

Lane discipline (keep right!) is rule #1.
Dutch holidaymakers ( they're the ones with roof boxes) seem to be the main offenders.
Portuguese trucks in particular have an alarming habit of pulling out without warning.

Driving styles change with the weather, but the traffic density is a greater factor.
There are more impatient people on the busier motorways!
The max speed in France drops to from 130 kph to 110kph when wet.

A large number of autobahns have new lower limits. Typically 100 kph.
This is down to the state of the crumbling concrete surfaces, which also do a great job of shredding tyres....

Speeds are almost always lower for a reason: junctions; autobahn used by slow local traffic;
bridge repairs.

And finally, as a tv motorway cop droned:

There is simply no way that is going to happen in UK (although I completely share your dream).

One of the issues with very high speed motorways is noise pollution. One thing I have noticed on the autobahns is that there are more and more Lärmschutz (noise abatement) restrictions between 10pm and 6am which unfortunately coincide with the quietest times traffic-wise. Speed is limited to between 100kph and 130kph depending on proximity to dwellings.

So here's a thought, say they decided to remove the speed limit altogether, what speed would you go to on a motorway?

Obviously traffic would dictate it but if you were faced with an empty motorway with no limit in good conditions would you put the foot down or would you stick to a certain limit?

I have done over the ton on motorways but when I reach my destination I always think that if I had a blow out then much less chance of surving it at 100 than 70! I also notice a huge difference in fuel economy, as much as 10mpg between 70 and 80.

I reckon once the novelty of no limit died down, then I would probably still do a max of 80!

From one point of view most ignore it and most would ignore a higher limit so why change.

Another point of view - if this was open to public debate who would the politicians listen to - those who want to reduce accident severity, carbon emissions, ban large engines etc so it would come DOWN and not go up. - Best not to open the debate then - leave as is.

Was this because the road was crowded or because they were saving fuel. I can't be the only one that's noticed that the price of petrol has gone up.

Obviously traffic would dictate it but if you were faced with an empty motorway with
no limit in good conditions would you put the foot down or would you stick
to a certain limit?

If visibility were ok, then I've already done 165 on the autobahn in a GT3, having newish tyres, Porsche approved helps the confidence, as does having a car that's still 26mph away from its top speed.

Most of Britain's congestion problems (on roads and elsewhere) are caused by the fact that the population is so high. Perhaps we should try and restrict the growth of the population before the whole country becomes totally gridlocked.

and cars are very much affordable [in spite of stealth taxes]!

Population alone has nothing to do with congestion. For example, India has very few cars compared to its population yet there are severe traffic congestions.

More cars + less roads = Congestion

Into a demographic time bomb. Not enough kids to look after parents when old and work thus destroying the traditional family support network so more intervention from the state required, an aging workforce, and a generation of spoilt lads (mainly).

How would you promote this population control ?

basically this thread is ANY excuse to let little old me go faster than 70 in my car.
OK most folk do 80 now, raise limit to 80 & same people will then do 90
yes cars are safer but same Mk1 humans use them
They are fooling no one
on green issues alone the limit should stay at 70
unless you didnt notice oil is running out which is going to be very interesting how will people explain in 400 years time how the human race discovered oil and used incredible amounts of it up till it was all gone in about 190 years ?

Actually not true - the probelms are that the GNP per head is so high. That is why third world countries with huge populations only have localised traffic problems.

GNP per head produced the same gradient line as car ownership per head and the largest of both when I last saw the graph was the USA with 6 cars per 10 people (and that includes those too old and too young to drive so effectively more than one per driver.

Lots of people would like to be allowed to do 80 mph legally on motorways. The problem is that if the limit was raised, all those who already do 80 will be doing 90 instead and those who still want to keep to 70 will become victims of road rage.

If M25 style variable limits are rolled out across the motorway network, which is probably a long way off, I think it would be viable for the controllers to be allowed to set the limit at 80 mph when there's little traffic and good weather conditions.

However, on environmental grounds, I don't think limits should be raised - as mentioned above, oil is going to become scarce and so we need to eke out what we can.

It's not illegal on the autobahns.

There's certainly no point in discussing global warming or oil reserves in the same thread as speed limts.

Ooops, I just did.

It's a lowest common denominator-type of issue. A 30 mph limit would save lives, but at what "cost"?

They could limit the number of vehicles allowed in the UK, so you'd have to bid to get one, with 1m new vehicle bids allowed p.a.

There are in fact more green fields than we think, as you can see on google earth but maps show roads as being about 15 miles wide on some scales, so people think the country is covered in them.

I'll give you a clue. I stated in my first post that I wanted variable limits across the whole motorway network with this coupled with the maximum limits raising. The one time that I've driven over 160mph I'd got three miles of straight motorway in front of me with no other cars in front of it. I was back down to a sensible speed by the time I'd reached the curve at the end of the straight. The only person I'm putting at any risk driving like that is me and the risk with £1000 of recent tyres on a car that's capable of much much more really is minimal. Far far less than cross plys on a moggie minor at 70mph.

If we let drivers think for themselves then there's a chance that they'll start assessing risk and driving well, rather than blindly listening to the mantra "speed kills." It doesn't, its an abject noun and abject nouns don't kill. Crap driving and other road use kills. If we concentrated on that and improving road engineering then we'd be in with a chance of reducing the number of people killed on our roads. Since we in this country became reliant on speed cameras for our road policing then road deaths haven't really shifted. Until then they'd been steadily falling.

It doesn't work like that though. Traffic laws have to account for the lowest common denominator. Just because you might be a skilled, attentive driver in a well maintained car doesn't mean that 90% of other people are. How would you then go about setting speed limits based on the capability of an individual and their vehicle?

Speed limits are set to allow most people to drive to an acceptable safety margin.

Speed kills might be a simplistic statement but it's undoubtedly true. The faster you go the less time you have to assess, plan and act - and you also reduce the time that other traffic you're interacting with has to assess, plan and act. Reduce the amount of time people have to complete a cycle of that process and the number of mistakes will increase. Some of those mistakes will result in accidents. A speed limit of zero plainly won't work so they're set based on a moderately skilled driver's ability to operate a standard vehicle safely on specific road types.

If speed limits were too low in the UK then we'd see differences around the world, but that's not the case. In urban areas 30MPH/50KPH or lower is the norm. Outside of rural areas it tends to be around 60MPH/100KPH. Motorways vary a little, largely down to different traffic densities and designs of road (distance between junctions, corners, frequency of tolls etc..) Only Germany has a system with no limits and that exists on only a proportion of the motorways. It still exists only because of political sensitivity in Germany to changing it - it will change eventually.

"Speed limits are set to allow most people to drive to an acceptable safety margin"

Except that the 70-limit in the UK was introduced as a (temporary!) fuel economy measure.

A Canadian study found that "that the incidence of crashes depends more on variations in speed between vehicles than on absolute speed, and that the likelihood of a crash happening is significantly higher if vehicles are traveling at speeds slower or faster than the mean speed of traffic".

Sounds plausible to me...

No it wasn't, it was introduced because of a lot of crashes.

You're right FT - sorry. It came in in 1965, before the oil crisis. It was meant to be temporary, though...

It doesn't work like that though. Traffic laws have to account for the lowest common
denominator.


But they don't have to be policed and enforced in a way that encourages the lowest common denominator to think that blindly listening to the mantra instead of thinking for themselves is acceptable or safe. Are you really suggesting that the lowest common denominator is something that should just be accepted at whatever level it happens to fall to? I don't see any reason to throw in the towel like that on driving standards.

I don't like to see hot hatches racing around my village at 50mph. When it happens (not particularly often), it's quite alarming. What is equally alarming, and much more prevalent, is cars travelling at a steady 30mph along the entire road, with drivers apparently not adapting (in terms of speed, road position, etc.) in any way to the continuously changing set of hazards around them.

Granted, if I (as a pedestrian) am hit by one of the 30mph, "I'm safe because I'm not exceeding the speed limit" bowling balls I am much more likely to survive than if the boy racer hits me. But simply slowing all the cars down sufficiently that driving into pedestrians becomes OK as it doesn't usually kill them is, in my opinion, a criminally irresponsible policy, and a dereliction of duty on the part of those responsible for road safety.

From DtF stats: "Fatality rates for car occupants more than halved between 1980 and 1993 from 6.2 deaths per billion passenger kilometres in 1980 to 3.0 in 1993. Fatality rates since then have continued to decline, but at a slower rate, to 2.6 in 2005. If you note the change of "slope" in the rate of decline, this occurred before speed cameras were introduced on any scale. As for "let drivers think for themselves then there's a chance that they'll start assessing risk and driving well" - we've been there before, they didn't. The French imposed stricter speed controls: they have reduced KSI rates significantly. However, they are not trapped in the Gatso cul de sac we've entered. Personally, I think they are of limited use, and are subverted by detectors. More covert cameras, more police or civilians to release police from the office/canteen, and drivers would not be so complacent.

"Fatality rates since then have continued to decline"

Rates are not the same as totals. Fewer deaths/1000 is still more overall when there are more motorists...

(And the corollary is that rates go down if the sample goes up)

The biggest decline in death rates took place during the 'oil crisis' in 1973/74. You will of course recall that speed limits on non-motorways dropped to 60 on dual carriageways and 50 on other roads.

Death rates dropped like a stone.

The 70mph limit is there because a significant number of 'drivers' are too stupid to be allowed to drive above that speed.

I live not too far away from the 'Haughley bends' on the A14. Too many inadequate drivers were not capable of reading the conditions and were taking the bends too fast - and killing themselves. So, a 50mph limit was put in place. This was not good enough - they still were killing themselves (let Darwin's Law reign, I say). Anyway, the road is now being straightened at an estimated cost (to us sensible folks) of £32M. So, presumably the 70mph limit will be restored but, please, that's enough for these loons.

I was reading a road test of a new Aston Martin and the road tester talked of cruising at 120 mph. on a trip up to Huddersfield. It was a DB4 and the year 1961. Most cars struggled to get to 70 mph then. Folk then would not believe that in 40 years beyond 70 mph would be illegal , that 35 would get you a ticket in a 30 zone and smoking inside would be a crime!

Progress eh ?
