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.
• Every answer explained, with the part of 49 CFR or the state manual it comes from.
• 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.
• Progress tracked topic by topic, so you know what is still weak.
• 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.
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 bank of any official exam.

The App Store now lists Spanish as an app language. Plus text fixes.
