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

The Wyoming 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 Wyoming laws that affect trucks operating only in Wyoming:

Wyoming has adopted the remainder of the federal laws that apply to all over the road trucks without further modification.

Driver Qualification

Wyoming has adopted Part 391 of the Federal Regulations with one notable difference. Drivers must be at least 18 years old, not 21.

Hours of Service

Wyoming has adopted Part 395 of the Federal Regulations with one modification: Drivers hauling non-hazardous materials within a 150 air mile radius of the normal work reporting location are exempt from the logging requirements of Sec. 395.8.
