DMV Prep is an independent, free study app and website for car permit, CDL, and motorcycle knowledge tests in all 50 states and Washington, D.C.
Official driver handbooks are the source of truth, but they are not always easy to turn into a daily study routine. DMV Prep converts that material into practice questions, explanations, focused study paths, road-sign drills, and realistic state exam formats. There are no ads, subscriptions, accounts, or leaked exam questions.
DMV Prep is not affiliated with any state DMV, licensing agency, the Federal Motor Carrier Safety Administration, the Federal Highway Administration, or the Motorcycle Safety Foundation. Agency names and links identify the official source visitors should confirm before taking action.
Questions and state facts are tied to official handbooks, agency pages, or federal regulations. Dated permit-requirement pages show when their source was last checked. The complete process is documented in our content methodology.
Rules change and source documents can be interpreted incorrectly. If something looks wrong, email [email protected] with the state, page or question, and the official source you found. We investigate specific reports against the cited material.
