There & # 39; S a lot of noise APUs (Auxiliary Blocks or generators) in those days. Thus, the federal government allows up to 400 pounds for trucks with APUs- or any device used to reduce fuel consumption and emissions. It & # 39; part of idling reduction strategy- encourage truck drivers and trucking companies to install the APU. But this does not mean that you can always get it.

This means that in one state may be allowed to work up to 80.400 pounds. but in this state, you may be limited to 80,000 pounds. in spite of the federal government and # 39; s decision. Many states already have weight tolerances above exemption from the weight of 400 pounds, so that the solution does not actually affect the enforcement proceedings.

Be prepared to show how much documentation as possible, if you run into a road block!
