Surface Transportation Assistance Act

The Surface Transportation Assistance Act directs DOT to create the National Network (NN) where States would be required to allow the operation of tractors with single and double trailers; it covers about 150,000 miles. It set minimum length limits on single trailers (48' or grandfathered length) and double trailers (28.5' per trailer in Western double configuration), with no overall length limit. The act authorizes the Motor Carrier Safety Assistance Program (MCSAP). States agree to adopt and enforce parts of the Federal Motor Carrier Safety Regulations (FMCSRs) and Hazardous Materials Regulations (HMRs) against interstate carriers and to adopt and enforce regulations for intrastate carriers that are "compatible" with the FMCSRs and HMRs.
