We have been bimbling around France for a few weeks now and I have taken great care to adhere to all the speed limits, sticking to the letter of the law to the point where it’s turned into bloomin’ hard work. One speed limit I can’t get my head round though is signposted everywhere on the N10 dual carriageway so it must be correct and that’s 80kph for any vehicle over 3.5t and no overtaking either. My van is plated at 4.5t and was last weighed fully loaded at 3.75t. This is incredibly difficult to do in practice as there’s always vehicles doing 70kph you want to get past yet you cant overtake, but French lorries come bombing past me all the time in the outside lane seemingly without a care in the world. What am I doing wrong? Have I misunderstood the signage? Am I the only one actually sticking to the law?
