CDL Prep is built for one thing: passing the written CDL test in your state. Most practice apps give everyone the same national question bank. But the CDL knowledge test is administered by your state, and states differ. In California, any vehicle towing a trailer is held to 55 mph — a generic national app will teach you the answer that fails you at the counter. So we read all fifty official state handbooks. 36 states publish rules of their own, and we wrote questions from them and cited the page. The other 15 publish the federal manual unchanged, which means the federal bank covers their test in full — and we say so rather than pretending otherwise. WHAT YOU GET - Questions written from the official sources: the FMCSA federal knowledge requirements and every state's own commercial driver handbook. - An explanation on every single question — not just which answer is right, but why the tempting wrong one is wrong. - The handbook section behind every answer, so you can check us. - State-specific questions clearly marked, so you know when the rule you are learning is local. - Honest coverage: where a state publishes the federal manual unchanged, the app says the federal bank covers it in full rather than promising specifics that do not exist. - Timed exam simulation scored at the real 80% pass mark. - A study mode that shows the answer as you go, and a review mode that drills only the questions you keep missing. KNOWLEDGE TESTS COVERED General Knowledge, Air Brakes, Combination Vehicles, HazMat, Tanker, and Doubles & Triples. HONEST PRICING General Knowledge is free, with every explanation and citation included — the whole test, not a teaser. Endorsements unlock individually, or all of them at once for less than the sum of the parts. One payment. No subscription, no trial, no countdown timer. WHO THIS IS FOR Anyone taking a CDL knowledge test anywhere in the United States — first-time applicants, drivers adding an endorsement, and drivers returning after a lapse. Every question is grounded in the official state handbook and the FMCSA knowledge requirements, and cites the page it came from. CDL Prep is an independent study aid. It is not affiliated with, endorsed by, or connected to the FMCSA or any state licensing agency.
