Montana Trucking Laws

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 Billings may own a truck that only makes in-state deliveries.

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

The following provisions are an overview of Montana laws that affect trucks operating only in Montana:

Driver Qualification

Montana has adopted Part 391 of the Federal Regulations with two notable differences. Intrastate drivers may be as young as 18 years old as long as they are not transporting hazardous materials. Also, waivers of certain physical qualifications may be granted if prescribed criteria are met.

Montana has adopted all other federal laws that apply to all over the road trucks without further exception.
