About the Delaware CDL knowledge test
The General Knowledge test is the written exam every CDL applicant sits, whatever class of license they are working toward. The questions come from the Delaware CDL manual, they are multiple choice, and you need 80% to pass. Delaware Division of Motor Vehicles gives the test, and passing it is what earns your commercial learner's permit, the permit you hold before taking the skills test in a truck.
What it covers
Our 10 free questions and the full 81-question General Knowledge bank are drawn from these manual sections:
- Vehicle Inspection
- Basic Control of Your Vehicle
- Shifting Gears
- Seeing
- Communicating
- Controlling Speed
- Managing Space
- Seeing Hazards
Endorsements such as HazMat, Tank, Passenger and School Bus are separate written tests on top of this one. See which Delaware CDL endorsements you need before you book anything, because the endorsement you are missing decides which tests you sit.
What Delaware requires
- The CDL learner's permit is valid for one year and cannot be issued or extended beyond one year from the original issue date.
- Delaware switched to the modernized CDL skills test (revised vehicle inspection and control skills) at all locations on February 26, 2025, and gives applicants a checklist aid.
- CDLs can only be renewed within 30 days before they expire.
- A CDL with a HazMat endorsement is issued for 5 years instead of 8.
Checked against Delaware Division of Motor Vehicles on September 16, 2026. Rules change, so confirm anything that affects your booking before you travel.
