The U.S. Department of Transportation (DOT) holds a high standard for over-the-road vehicles using air brake systems. Heavy-duty vehicles that travel on the roadways, such as semi tractors and trailers and buses, require DOT-approved air brake systems, and each component of air brake systems must comply with DOT standards. Other heavy-duty vehicles, like agricultural and off-road equipment, that use air brakes may not require DOT approval.
