As with all speed limits if you obey them you will not get caught or fined, its as simple as that.
As for lower limits where there are road works and/or lane restrictions there is a 15 mile stretch on the M1 near us that has been ongoing for almost 2 years now. If you calculate how long it takes at 70 mph its 13 minutes. At 50 mph its 18 minutes.
So it adds 5 minutes to my journey time (probably each way).
If I need to get to my destination on time I set out 5 minutes earlier but its very easy to loose more than 5 minutes at lights and in traffic before I even get to the M1.
