CDL practice tests by state

Every U.S. state — plus the District of Columbia — issues its own Commercial Driver's License, but the knowledge exam is the same model exam everywhere thanks to federal CDL standards under the FMCSA. Pick your state below to see the full list of endorsement tests and the official agency that issues your license.

How CDL rules vary from state to state

While the knowledge tests themselves are derived from the federal AAMVA Model CDL Manual, individual states do customize a handful of policies. Each state controls the fee schedule, the appointment system, the form of identity documents accepted, and the number of attempts allowed before re-testing. Some states require a CDL applicant to hold a Commercial Learner's Permit (CLP) for at least 14 days before scheduling the behind-the-wheel skills test. Others administer the general knowledge exam in multiple languages.

Beyond those administrative differences, every state must follow the same federal floor for what is on the test. That means a Hazmat (H) endorsement earned in Florida covers the same regulatory ground as one earned in California, Wyoming, or Maine. The Commercial Driver License Information System (CDLIS) tracks every CDL nationally, so a disqualification in one state immediately disqualifies you in every other state.

If you are moving from one state to another, you do not have to re-take the CDL knowledge tests. You will need to surrender your old license to the new state's DMV, present medical certification, and pay the transfer fee. Your endorsements transfer with you in nearly every case — though some states require an in-state Hazmat application because the TSA security check is tied to your residence address.

The questions you'll practice here are the same in every state. Pick your state above to see the official DMV agency, the endorsements available, and direct links to every practice test.
