Quote ="upthecats"There's a hell of a lot of poor drivers on the roads, and on motorways the majority are not lorry drivers!!
On the parts where there are no restrictions in place and the traffic if flowing freely.... any car doing 50-55mph should be stopped and banned from driving on the motorway. If and when you ever get in a lorry and drive on motorway's you will know exactly where I am coming from....
As for the 50 speed limit, I'm sorry but I don't believe anyone anywhere would get clocked and a ticket for doing 53/54 never mind 51......it's always been my thought that you will 99% of the time get away with doing 10% over the limit....
And as for driving 45-48 to avoid getting a ticket......if you can't maintain a speed of 50mph on a motorway I'd question your ability as a driver!....nearly as bad as those who will happily drive along a road at 30 for a couple of miles and then as soon as they come to a speed camera drop to 27....why oh why oh why!!

Agree with most of the above, in that 99% of lorry drivers are undoubtedly the best drivers on the roads, however there are exceptions (the last one I had dealings with was as drunk as a skunk, and was virtually bouncing off the crash barriers on the M62 with next-to no windscreen in.....he is currently serving a 9 week stretch in Armley, and is then banned for the next 3 years !!!!)
With regards to your comment on doing 53/54 mph in a 50, you are correct, as all NORMAL speedometers generally read approximately 10% under the ACTUAL vehicle speed. If you have a SATNAV you will find that the SATNAV's indicated speed is usually about 10% higher than your speedometer's indicated speed, and it is your SATNAV that is correct !!!! So if you are going at 50 mph on your speedo through the roadworks, then in reality you will be travelling at around 46/47 mph, getting overtaken by all the lorries.
Calibrated tachographs in lorries are more accurate than speedos in cars, so whilst lorries are all electronically limited to 56 mph, when they overtake you in the roadworks at 56 mph, and you look at your speedo, you could easily believe they are doing in excess of this !!!
Whilst the normal recommended guidelines for a speeding prosecution are 10% +2mph (ie 50+5+2, 60+6+2, 70+7+2), I BELIEVE that on some camera-monitored roadworks sections on motorways, they do set the limits lower.....I will leave it up to you to decide whether you consider this to be a safety issue to protect the roadworkers, or alternatively view it as a money-making exercise by the Government !!!!
And here endeth todays lesson on speeding..
