Question:
Does anyone know if or where a federal dot regulations can be found that requires us to note on the tractor "FIRE EXTINGUISHER INSIDE". I am told there is such a dot regulation that requires that notation on the door of the tractor that the extinguisher is stowed...I sure can't find in the FedRegs. I see the vinyl signs in the truck stops and on trucks and I just don't know. Would appreciate any comebacks on this one
