The term "commercial motor vehicle" is specifically defined by regulations that categorize vehicles based on their gross vehicle weight rating (GVWR). According to the Federal Motor Carrier Safety Administration (FMCSA), a commercial motor vehicle is one that has a GVWR of 10,001 pounds or more. This definition is important for ensuring proper safety standards and regulations are applied to larger vehicles that typically require special licensing and compliance with additional safety rules.

The threshold of 10,001 pounds is significant because it distinguishes commercial vehicles from lighter vehicles, which may not require the same levels of regulation or may not pose the same risks associated with larger, heavier vehicles on the road. Vehicles weighing less than this threshold are generally classified differently, often falling outside the regulatory framework that governs commercial motor vehicles.

Understanding this distinction is essential for medical examiners and those involved in DOT physical exams, as it impacts the requirements for licensing, compliance, and safety standards necessary for operating such vehicles.
