Commercial trucking is one of the most heavily regulated industries in the United States—and for good reason. Tractor-trailers, 18-wheelers, and other commercial motor vehicles can weigh up to 80,000 pounds and travel hundreds of miles per day. When safety rules are ignored, the consequences are often catastrophic. Trucking laws exist to protect the public, regulate the industry, and reduce serious and fatal truck accidents nationwide.
These laws are primarily federal, meaning they apply across all states and govern how trucking companies, drivers, and related entities must operate. This article provides a clear, nationwide overview of trucking laws, including who they apply to, what they regulate, why they matter, and how violations often play a critical role in truck accident injury claims.
