Idaho Truck Accidents

The Federal Motor Carrier Safety Regulations (Title 49, Parts 350-399) govern all vehicles engaged in interstate traffic.

There are some situations where a tractor-trailer or other commercial motor vehicle is involved in only intrastate travel. For example, an appliance store in Moscow may own a truck that only makes in-state deliveries.

The Idaho Department of Public Safety has adopted Title 49, Parts 382-384 and 390-399 of the federal regulations.
