Slip road use. - Old Navy
I was advised by a police traffic driver to use the right lane of a slip road when joining a motorway or dual carrigeway. His reason were that you can see back along the road that you are joining earlier and likewise people on the road you are joining can usually see you sooner. Most people merge right from the left lane, I usually use the right lane, not overtaking cars in the left lane. The only down side is this can impede the progress of the swoop to lane three drivers. Anyone know why "keep left" seems to over ride all else for most drivers, or is it the "use the full width of the road when nessisary" part of my HGV training kicking in.

Probably because using the left lane allows you to escape on the hard shoulder if it all goes horribly wrong, particularly if the traffic is heavy in the left lane of the slip. To me the rh lane of the slip is for the the swoop to lane three drivers.

I would also suggest that visibility is better in the left hand lane (turning the head in addition to using mirrors) and generally a longer parallel run in.



Slip road use. - ForumNeedsModerating
Yes, agree PMH. All my instincts & experience point me towards LH lane - more time, more space, more saftey margin. You also know nobody is likely to baulk you should you need to abort & use the HS. The observation thing - well I use rearward look over shoulder for most obs. , & only mirrors when about to join & so nearly parallel , as you mentioned (as well as obs. on those behind on the slip road of course).

I do tend to use the inside lane on slip roads. Most onslips where I am have an arrangement where the two lanes reduce back to one at the end.

I don't mind cars using the right hand lane and overtaking me - as long as they don't overtake in the single lane bit. Trouble is - quite a few do, creating a situation where either they get too close, are forced into lane 1 across the chevrons or I have to run up the slip road longer than I ought to to let them past - and run the risk of running out of onslip.

If the slip road goes down on to the motorway, then there is an advantage to using the right lane, as you can see over the edge of your roadway sooner.
Similarly, if the slip road goes up on the motorway, it's advantageous to use the left lane, as you can see over the edge of the motorway sooner.

There's not really much of a difference though - the important thing remains to ensure you're not level with anyone when you reach the end of it - either on the slip road with you, or in the first lane of the motorway.

My instructor said the same to me. I am not sure why most, perhaps, use the LHS.

the swoop to lane three drivers.


This is not good technique.

What happens if you try to enter in the right hand lane and a succession of `straight to lane three jockeys` blast past in line on your left ? and you then find you can`t enter the motorway as a line of close running trucks can`t move to lane two due to congestion?

One in a thousand chance of that? Bet it gets a lot less if all normal speed traffic on the slip road start using the right lane.

Those straight to lane three 95MPH boys will surely just blast down on the left.

Meat in a sandwich doesn`t really describe it as the guy in the right lane could find himself at the point where road space ceases to exist.

Recent experience joing the M5 every evening has proved that joining on the RH lane works best. Not only is visability better but it prevents the "straight to lane 3 boys" from overtaking agressively on the slip road - something which I find very disconcerting when joining a busy Mway.

.. RH lane works best. Not only is visability better but it prevents the "straight to lane 3 boys" from overtaking agressively on the slip road..

But don't they just tailgate you instead down/up the slip road? - as, if not more, disconcerting I would think - for me anyway.

Like most things in life I think it depends on the circumstances. When you get two junctions close together I'd say it was obvious that the left hand lane gave you a greater degree of safety, mainly because lane one of the motorway is looking to cut your path off. I'm thinking M56/M53 junction and the junction for Outlet Village, and I think Knutsford services exit onto the M6 is also on top of another junction.

The left hand lane gives you more time to find a gap and slot in, the right hand lane can mean you have to almost stop to wait for a gap.
Slip road use. - Old Navy
Thanks for your views everyone, I usually drive north of the lake district where traffic density is lower. I will keep in mind that the safer option may be the left lane in heavy traffic, using the hard shoulder as an escape route if things go wrong.

Right hand lane for me. Taught during advanced driving course for 'see and be seen' purposes. On a personal note, it also lets you get past the mentally challenged who feel it's perfectly ok to join a m'way at 20mph.

MLC - you still get these in the RH lane even when the LH is clear!

M18 to M1 North & South bound - I always use the left hand filter lane here.

1. You have a large hardshoulder to escape to unlike the RH lane.

2. You have a better field of view as you join the M'way.

3. White lines - more than once I have had a 'chevron jumper' both left to right & vice versa here!

Wherever possible, I'm always up to m/way speed by the time I'm at the bottom of the slip road. It's easier to slow from 60mph to 50mph if necessary, than it is try and speed up from 30 to 60.

I was stuck behind an old boy in Rover 45 last night who joined at 30, positioning himself in the middle of the slip road, preventing any overtaking. He merrily pulled straight into lane 1 without a care in the world. The artics coming up behind him were non too happy, nor were I and the others stuck behind him who had very few options. What should be a smooth, filter flow was a haphazard and dangerous experience.

Unfortunately I'd just finished work, otherwise we may have been having words. (Although I'm sure he would never have accepted he did anything wrong)
Slip road use. - b308
I hope none of you sliproad outside lane hoggers are the ones that prevent me having a clear view of the motorway be getting in my sight line as I come down the slip road? - surely you can wait until you join the motorway before you start overtaking? Also surely the same rule applies as on any other road - if the inside lane is clear you should be using it......

I accept that there are occassions where you can overtake on a sliproad (the Rover driver above is a good example), but most of the time its surely best to wait??

AArgh... I was about to say I didn't really mind which lane I was in on a slip road until you reminded me of them, mlc...

And there are others who just do it blindly instead of trying to slot in between two vehicles in the nearside lane, just pull slowly into the motorway without signalling or looking, total idiocy.
Slip road use. - Westpig
if there are two lanes on a m/way slip road, then surely the road engineers who have designed and built it have planned for traffic to use.. er two lanes...and the slower traffic would be in the nearside lane and the faster traffic in the off side lane, overtaking the slower traffic....what's wrong with that?

you tend to find that when you get to the actual m/way there are no longer two lanes (unless there are those white cross hatching type things to ensure you stay in that lane), so that all traffic can merge into the main carriageway safely

i see no problem at all with whizzing down the o/s lane and would be irritated if someone wanted that lane to 'mimse' when the nearside lane is free
Slip road use. - b308
Those two lanes merge into one BEFORE joining the motorway - that, to me, means that you should have overtaken the other vehicle well before reaching the bottom of the slip road and not force the driver on the inside lane of the slip road to have to take avoiding action by not being properly prepared to slip into the inside lane of the motorway beacuse you were too concerned in overtaking on the slip road.

Too often I've seen people go shooting down the slip road overaking everything in sight without actually planning on how they are going to join the motorway itself safely.

The slip road is there to get up to the correct speed to join the traffic on the motorway proper, not to start racing/overtaking everyone else - I've no doubt that you are all considerate drivers who would never do that, but regretably there are many that aren't!

TBH if the advanced driving mob think that its better to stay in the outside lane that seems to me to be a decent argument for only having one lane like they do in mainland Europe, that way we wouldn't have the racing and on the odd occassion that you have some slow Rover driver you could always use the hard shoulder in an emergency to get up speed safely.
Slip road use. - Markoose
slips roads are a nightmare. I believe they are the one piece of road that it is most important to accelerate up to speed on. On the normal type of two lane slip road that most people are talking about here I would tend to merge from the right and would overtake anything that looks like it isn't going to merge at 70mph (or with the traffic flow if lower) only because I want to spend as little time as possible in the vulnerable position of merging where sometimes I have people from the middle lane of the motorway pull into the gap I wanted to merge to or have someone close that gap by moving closer to the vehicle in front (or have a lane swooper overtake me at the last minute and use the gap up). If I have a slow-coach in the left lane of the slip who I couldn't overtake safely and who wants to merge at 50 in front of a lorry I do two things 1) get scared 2) merge behind them. I don't know what else to do short of using the hard shoulder and stopping isn't an option. I've almost been sandwiched a couple of times because of slow mergers, one of those times was where a lorry decided to "teach me a lesson" by not slowing down and almost collided with the back of my car. I don't see why I should have been the object of his fury considering I was practically sitting in the back of the dumb cow in front's range rover at the time with beads of sweat coming out of my forehead. I am thinking of taking an advanced driving course so that I better know how to deal with this kind of thing and save my blood pressure. When I'm actually on the motorway a pet hate is that so many drivers seem to think that I should move over to the middle lane to allow them to merge rather than adjusting their speed. By and large I do move over where it is safe or reasonable to do so just to make everyone's life easier but sometimes I may decide not to if I don't feel it's safe for me to change lanes and maybe just one or two cars are joining, but the amount of times I've found that I have had to swerve as an oblivious driver just pulls out toward the side of my car and not a few of them started gesticulating and swearing.

Those two lanes merge into one BEFORE joining the motorway


They don't always, you know. There are quite a few places where there's even cross-hatching between the slip-road lanes to make it clear that the outside lane exits into the motorway before the inside one. It isn't always that explicit, but if both slip-road lanes are still there when the slip road joins the motorway, I would expect people in the outside lane to exit as soon as they can, not squeeze into the inside lane to put off the evil moment. Of course there are probably some drivers who do that.
Slip road use. - Brian Tryzers
>...should you need to abort & use the HS

Has anyone here ever done this? Not me, in nearly 20 years.

As for Markoose's slowcoach, if there's really no opportunity to get in front, the thing to do is to anticipate the situation and back right off, changing down if necessary to allow you to pick up speed again quickly. That gets you right away from the problem caused by the slowcoach, and probably allows you to merge some way behind, into the space left by drivers already in lane 1 pulling out to pass him.

The sliproad situations that scare me most (and I'm doing a lot of motorway driving at the moment) are mostly caused by drivers forgetting that the basic rules of safe spacing apply to sliproads too. I tend to be driving at busy times, so I do a lot of it in lane 1 at 60-ish, where I can leave a good clear space in front of me. (Lanes 2 and 3 are frequently nose-to-tail and barely any faster.)
What I find, approaching a junction is one driver tootling down the sliproad without any apparent attempt to assess the speed of the traffic or to pick a safe gap to merge into. This wouldn't be a problem - I could adjust my speed up or down a little to pick the gap for him - if it weren't for the four drivers behind him bunching into a 45mph phalanx and then all expecting to merge in front of me.

And, as I've mentioned here before, whatever the stereotype of the French driver, this problem simply doesn't happen there - not to me, anyway. Perhaps we could do with the equivalent of their Cedez le passage signs at the bottom of our sliproads.

Keep left, that way those of us with cars that actually accelerate can pass you.
Slip road use. - Bilboman
All part of the bigger picture of "zip merging" which seems to be something which will never, ever catch on. Most drivers are too slow, too fast, too jerky, leave too little space or simply do not want anyone to "get ahead" in any circumstance and would rather join a multiple pile-up than (horror of horrors) give way to the right. Or the left. Or to an older/newer/German car. Or to anyone, ever!
The 10% of us (am I being over optimistic here?) who maintain an intelligent distance, speed up or slow down smoothly to prepare to enter a gap, look round, indicate, remember the different driving dynamics of HGVs, keep an eye out for LHD drivers, move into lane 2 to allow filtering in etc., are, literally, a dying species!
Slip road use. - Lud
Ought to be an essential part of the driving test. People who don't accelerate up to nearside-lane motorway speed before signalling clearly and merging neatly between two cooperative vehicles in that lane, unless baulked by idiots in that lane which should be apparent to the tester along with the candidate's behaviour under fire, should carry an automatic fail.

Might have to pay the testers danger money though especially in the M6 region...

Thinking further about this, and noting a post in another thread that states with apparent authority that motorway driving as part of the test is a 'non-starter', I wonder why this should be? That post was in reply to one pointing out that there are no motorways in the far northern wastes of our land. What is to prevent driving tests being conducted only where there are motorways? It is often said that a driving licence is a privilege, not a right. It is already much more difficult for some people to get one than for others owing to disparities in luck and natural talent.

The essentials of motorway driving should be included in the driving test. Or perhaps since L-drivers are rightly excluded from motorways, it is time for an official second stage, the green P or something, during which motorway driving can be learned. Jerky, anomalous or irrational behaviour, annoying and expensive on normal roads, can be lethal on motorways owing to the speeds used there.

Yes, vitally important - it's one place where poor skill and/or bad decision making can have a disproportionately catastrophic effect. If the 'no motorways nearby' is the counter argument to this (as mooted) - I suggest that lots of practice on a(n) NSL A-road dual carriageway instead - it shares many of the motorway characteristics & poses similar 'problems'.

I suspect part of the reluctance may be from the driving tuition/testing professionals themselves - I could understand them not being too keen with a nervous driver dicing with the HGVs, repmobiles & white van persons.

Yes Michael you're so right. If someone has a much more powerful car than mine and the eyes of an eagle, to swoop down to lane 3, I'm not going to argue with Range Rovers or BMWs. I'll stick to the LH lane of slip road. I only have to look in my mirror, back over my right shoulder and the blind spot, for lane 2 to 1ers. Far safer. I tried fast in RH slip lane once, only to be undertaken and nearly lose a safe merging point, as well as the potential last resort of the hard-shoulder or even stopping in the left, if simply not enough space to safetly merge. Being in the LH lane also allows you more time to back-off and pick up speed if necessary.

I agree but in this case I think that we're talking about the normal slip road - the one you refer to is, in effect, two seperate slip roads by the time it reaches the motorway as the cross hatching are solid white lines so you can't (in theory!) cross them!
Slip road use. - Leif
I generally prefer lane 2 (the right hand one) because it gives me control over the road and prevents someone else stuffing me. On occasion when I went in lane 1 (left hand) an idiot would hurtle down lane 2 and then position themselves between me and the motorway, preventing me from merging in. Thankfully such morons are uncommon.

I don't like the idea of continuing along the hard shoulder as you might have someone stopped on it, and sometimes it disappears anyway, as for example a bridge pops up. So best avoided.

But using the hard shoulder as an escape road is certainly far better than getting seriously in the way or causing a catastrophic crash. It isn't there for nothing after all.

Anyone who has looked at a motorway hard shoulder will be inhibited against using it except in emergencies. It tends to be strewn very liberally with nasty sharp debris and bits of car and tyre.

Slip road use. - Markoose
I've seen someone use the hard shoulder before, they were in front of me and I think they'd turned onto the slip road by mistake and wanted to turn around or reverse back out !!! they then tried to enter the motorway at 20mph (there was only one merging lane and I couldn't get past and was filling my pants) and so I was rude and jammed my hand on the horn until they panicked and pulled over onto the hard shoulder. I then floored it and merged semi-respectably... before cutting a car up in the middle lane, swearing at them and then swerving into lane three, where I lost control of the vehicle and got rear-ended but told the insurance company it was their fault. I might have made that last bit up.

I agree with the advice about backing off and then merging into the gap that other traffic will create when overtaking the slow-coach, sounds eminently sensible and I will try this next time. If I never post again it didn't work.
Slip road use. - hugopogo
I tried this today, its not so often that I get chance to in a 1 litre Micra... But the slip road was empty so I stamped on the accelerator and moved into the right lane... Visibility for me was tons better. So in future I'll play it by ear... I'm not gonna be getting in the way of any third laners but if the roads are quiet it makes sense I suppose.
Slip road use. - Manatee
There are two types of third laner. The predominant type will overtake and tailgate on the slip road. Serve then right when they run out of road in the process of blocking other drivers in the midst of a potentially hazardous manoeuvre.

The second type will use the right lane of the slip, but will hang back if there is traffic ahead to create a gap for acceleration - if lane one of the major road is clear, and there is a gap in lane two or three, they can take it without discommoding the drivers who were in front of them on the slip, and have the satisfaction of an efficient and speedy progress. If the gap isn't there, they can regulate their speed and join lane one with space to match speeds.

There's an absolute epidemic of old threads coming up - I don't remember this one.
