Safer Truck Act

Safer Truck Act - Amends Federal highway law to authorize a State to allow a single unit truck or bus without a trailer to operate on the Interstate System while carrying up to 20 metric tons (44,080 pounds) of cargo, packaging, and load securement materials regardless of the overall weight of the vehicle, its axle weights, or weight of its safety and energy conservation devices if the cargo is evenly distributed in a compartment or combined compartments at least 40 feet long, the overall height of the vehicle and cargo does not exceed the width of the wheelbase, the axles are positioned at the extreme ends of the vehicle, the gross weight and certified empty weight of the vehicle (including detachable cargo compartments) are marked conspicuously on the front of the vehicle in contrasting three-inch or taller letters and numbers.

Amends Federal transportation law to revise certain commercial motor vehicle width limitations on vehicles operating on the Interstate System and on Federal-aid highways to exclude from width calculations with respect to such limitations safety devices that reduce the possibility of death and injury if such devices fit entirely within the legal travel lanes of all roads upon which the vehicle operates.
