California DMV Prep 2026

California DMV Prep 2026 gives you mock exams to prepare for the California DMV knowledge test: signs, signals, road diagrams and the rules of the road. Every answer comes with an explanation, and your progress is saved to your account so you can pick up on any device.

It started as the web version of our iPhone app and has the same 20 mock exams, plus free lessons and practice pages.

California DMV Prep 2026 is developed by ChowChow Labs, an independent app studio based in Canada.

Questions are original, checked against the California Driver Handbook, and link to it so you can check each rule. Read how we write and check them, or see everything ChowChow Labs makes.

California DMV Prep 2026 is an independent study aid by ChowChow Labs. It is not affiliated with or endorsed by the California DMV or the State of California. The questions are original practice questions, not actual DMV test questions, and practice scores don't guarantee you'll pass. Always study the current official California Driver Handbook.
