CDL Road Test

What you need to know regarding Road Tests for Commercial Driver Licenses.

The Commercial Motor Vehicle Safety Act requires every state to meet the same minimum standards for commercial driver licensing. The standards require drivers to get a Commercial Driver License (CDL) to operate any of the following commercial motor vehicles:

  • A vehicle with a gross vehicle weight rating (GVWR) in excess of 26,000 pounds.
  • A combination of trailer and towing unit which exceeds 26,000 pounds GVWR with the trailer in excess of 10,000 pounds GVWR.
  • A vehicle designed to transport 16 or more passengers, including the driver.
  • Any size vehicle which transports hazardous materials which requires a Hazmat placard.

Drivers are required to pass different knowledge and road tests depending on the Classifications and Endorsements they apply for and for the type of license they currently hold. Before applying for a CDL license, drivers should thoroughly review the Commercial Driver Manual, which can be downloaded or is available for pick up at any DMV office.
