A broad regulatory and mechanical classification for road vehicles that exceed standard weight limits, typically anything over 10,000 to 26,000 pounds depending on local laws. This category encompasses semi-trucks, dump trucks, and large passenger coaches. Working on these requires specialized heavy-duty lifts, pneumatic tools, and commercial inspection certifications.
You need a commercial driver license to operate any heavy vehicle on public roads.
