Washington Truck Laws

As home one of the country’s busiest international crossings, Washington invites a steady stream of truck traffic every day. Highways that include Interstate 5, Interstate 82 and Interstate 90, as well as urban centers such as Seattle, Spokane and Tacoma attract tractor-trailers, buses and other commercial vehicles in large numbers. Unfortunately, that traffic volume leads to more than 1,300 commercial vehicle-related accidents every year, leaving hundreds of Washington residents suffering from injury or loss of a family member. If you’ve suffered from an accident with a commercial vehicle and believe the truck driver or trucking company’s negligence is responsible, contact Michael and speak with an attorney who will fight to hold the responsible parties accountable.

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

The Washington Department of Public Safety has adopted Title 49, Parts 382, 383, 384, 390, 391, 392, 393, 394, 395, 396, 397, 398, and 399 of the federal regulations.
