FAQs

What is the CDL exam?

 The CDL exam requires a written and skills test using the class of vehicle the driver intends to operate as a
commercial driver. 

Who takes the CDL exam?

A commercial driver’s license is needed if the vehicle meets the following criteria (check your state CDL manual for state specific requirements):

  • Class A: license class for combination vehicles with a GCWR of 26,001 or more pounds
  • Class B: license class for heavy straight vehicles with a GVWR of 26,001 or more pounds
  • Class C: license class for small vehicles with a GVWR of less than 26,001 pounds

The CDL requires test takers to be at least 18. However, if transport includes crossing state lines, the driver must be 21.

What is on the CDL exam?

The CDL exam is broken up into 3 sections: written, pre-trip inspection, and skills. The written test consists of 50 questions, with a required pass rate of 40 correct questions. The pre-trip inspection allows the driver to completely inspect both the inside and the outside of the vehicle.

How is the CDL exam scored?

Tests are composed of a combination of true/false and multiple-choice questions and require a passing
rate of 80%.
