I was told when i got my license that if you run a red light that you dont get a fine for it as there more forgiving for trucks, in the last 5 years i have been flashed 3 0r 4 times and never got a fine.
Thats got more to do with the way the truck is loaded, if something is unstable it should either be put behind something bigger and solid or tied down, found out all these things in the first 6-12 months of driving trucks now i never have a problem, you will find most good drivers that have been driving for a couple of years dont have these problems, if they do them there the type of people your company can do with out.
