CDL & Driving Test Practice

990 CDL questions. All eight federal tests. Every answer cites the federal rule it comes from. Practice for your commercial driver's license written test in English, in Spanish, or switching between the two whenever you want. Same question, same road sign, both languages. THE EIGHT FEDERAL TESTS · General Knowledge — 50 questions, 60 minutes, 80 % to pass · Air Brakes — 25 questions · Combination Vehicles — 20 questions · Hazardous Materials — 30 questions · Tank Vehicles — 20 questions · Doubles and Triples — 20 questions · Passenger Transport — 20 questions · School Bus — 20 questions Plus a practice round for the roadside English check that has left drivers out of service since June 2025. WHAT YOU GET • Timed practice tests with the real format: question count, minutes and the 80 % that 49 CFR 383.135 requires. • What you need to know, topic by topic: the part you read, with the article of the law under every rule. • A dictionary for your package: what every road sign and topic means, with the term in the other language and a search box. • An honest readiness number, worked out from your own answers. Not a promise that you will pass. • Daily streak and daily goal. • Save any question and drill it later. • 861 road signs, drawn one by one, searchable by name and by type. • Drill your mistakes until you own them: three correct answers in a row retires a question. • Works offline. Everything stays on your phone. The app also carries the driving licence test for nine Latin American countries, each with its own law. Free to start. One payment unlocks the truck driver pack for good — no subscription, no repeat charges. No ad ever covers anything: video only if you ask for it. And it works with no internet, so there is no server to go down the night before your test. Unofficial app. Not affiliated with the FMCSA, AAMVA or any state motor vehicle department. Questions are written by us from the federal regulations (49 CFR parts 383, 391, 392 and 393) and the official state CDL manuals, with the article cited in every explanation. They are not the question pool of any official exam.
