Class specific speed restrictions for relatively small vehicles under 3.5 tons are an unnecessary and confusing grey area for many safe and conscientious drivers. Many 4x4s and motorhomes weigh over 3 tons and are allowed to do the usual speed limit. This is unfair when a small van driver could receive a speeding ticket for doing 51 in a 60 zone. Especially if you consider reclassifing a van to a camper can move a vehicle from one speed limit to another. I am hoping in the light of the recent decision to move the motorway speed limit to 80, we could also bring these outdated and confusing restrictions to an end. As far as I can see they have absolutely no grounding in reality. It is of no use to anyone to make criminals of good people. If only the speed limits could be as simple as the illustration implies.
