Automated Knowledge Testing S​​ystem

Knowledge tests administered at most DMV customer service centers​ are given on a computerized system. The system uses touch screens and provides instant feedback about whether an answer is correct or not. In situations where multiple tests are required, the system will automatically advance to the next test in the session. For those with limited reading proficiency all tests can be administered with an audio assist option. (An examiner will add the audio assist option upon request.)

Limitations on Number of Tests One Can Take

Prior to visiting a DMV customer service center to take a knowledge test, study the appropriate handbook so you are prepared and know the material about which you will be tested.

You are only allowed to take the same test five times within a one-year period. If you do not pass the required test(s) in five attempts, you must get special permission from DMV staff prior to taking the test again. Before you are granted special permission, you will need to show what you have done since your last attempt to improve your ability to succeed on your next attempt. (e.g. you received additional instruction or tutoring.)

Recommended Time to Allow for Testing

Knowledge tests for Class D (regular license) and Class M (motorcycle license) each take about 45 minutes to complete. The tests are conducted on a walk-in basis. No appointment is necessary. CDL knowledge tests take at least one to one and a half hours. Allow enough time to complete tests prior to when the DMV customer service center is scheduled to close.​
