CDL Prep vs CDL 中文备考

Since April 17, 2026, the CDL knowledge test is given in English only across the United States. CDL Prep is built around that fact: study and understand the material in your language while you memorize the exact English wording you will see on the test. Bilingual mode shows both versions side by side — and English never disappears. WHY THIS APP IS DIFFERENT • Every question cites the section of the official manual it comes from. If you doubt an answer, you can check it yourself. • A report button on every question, with typed reasons. Errors get fixed because there is someone to tell. • Exam simulator with your state's real format: official question counts and passing scores, not generic ones. • Answers are shuffled by default: you learn the material, not "it's B". • Free, with no paywall. No accounts, no sign-up. WHAT'S INSIDE • Question bank by section: General Knowledge, Air Brakes, Combination Vehicles, Doubles/Triples, Tanker, HazMat, Passenger, School Bus and Road Signs. Every question comes with an explanation. • Practice with instant feedback, a timed exam simulator, review of your misses, and marathon mode. • Spaced repetition (Leitner system): the app keeps asking what you miss until you own it. • Pre-trip inspection trainer: the script you recite to the examiner, block by block, with automatic-failure steps marked. It is where most people fail, and almost no app covers it. • Official state manuals: download the PDF and read it offline. • A file on each state: licensing agency, minimum ages, and where it departs from the AAMVA standard. • Readiness score from 0 to 100 per section, computed so it cannot be fooled: five right answers out of five is not being ready. NINE LANGUAGES, ONE EXAM Interface and questions in English, español, français, português, русский, українська, 中文, العربية and ਪੰਜਾਬੀ. Bilingual mode teaches your language and the exam's English side by side. BUILT FOR THE ROAD Everything works offline: the question bank, the simulator, your progress and any manuals you have downloaded. No accounts, no sign-up. CDL Prep is free because it is supported by ads. We do not sell your data and we do not ask you for anything: if you decline ads or study offline, the app works exactly the same.

Always confirm current requirements with your state's licensing agency.
