i've got a lot of respect for truckies…. they've got a hard job as it is without dicks in BMWs or grannies in Pandas skitting about around them.
some of them are obviously idiots, but you'll find that in all trades.
if you can't see their mirrors, they can't see you. treat them as you would a cyclist; think for them and preempt what they might do.
oh, and don't brake sharply infront of them. your saloon brakes a lot quicker than his 18 wheeler and it takes him ages to build up speed/momentum.
… my best mate's old man used to be a truckie and had a fleet of 25 trucks before politics, fuel prices and the recession ruined his business .
