Flat deck, box truck?

Be careful, my last npr non HD (12,200 gvwr) box truck with 14ft box with your described setup made the truck over weight with full tanks. If you get pulled over for hazmat stuff and they weigh you with full tanks you could be in trouble either way.


This has been discussed at length many times, They go by weight, not gallons as per D.O.T. Regulations.

To get Hazmat registered to haul over 1000 pounds of corrosives you will have to get the CDL first then Hazmat.
