About USA DMV

USA DMV (usadmv.app) is a free study site for the U.S. driver’s license knowledge test, made by The Solana Labs, the team behind the USA DMV Test Prep app.

Not a government website

USA DMV (usadmv.app) is an independent study resource. It is not affiliated with, endorsed by or operated by any state DMV, the Texas Department of Public Safety or any other government agency. Practice questions are written to reflect official driver handbooks but are not the official test questions. Always confirm current requirements with your state’s licensing agency.

We do not book appointments, issue permits or licenses, process renewals or collect fees. For any of those, go to your state’s official licensing agency directly.

Where the questions come from

Our practice questions are written from each state’s official driver handbook and the CDL manual. They test the same rules and topics, but they are not the questions on the real test. Test formats and passing scores can change, so check with your state before test day.
