LEARN CDL + LEARN ENGLISH — AT THE SAME TIME
━━━━━━━━━━━━━━━━━━━━

Starting in 2026, FMCSA requires all CDL exams to be taken in English only. Roadside inspectors now enforce English proficiency under federal regulation 49 CFR 391.11, and drivers who fail the roadside English assessment can be placed out of service.

CDL Help is built for this new reality. Every question displays in English alongside your native language — so you learn CDL regulations and build English proficiency together. Toggle between languages with one tap to understand every term, every sign, and every rule — the same way you'll need to on the road.

This isn’t just about passing a test. It’s about keeping our roads safer. When you can read highway signs, communicate with inspectors, respond in emergencies, and complete reports in English — you protect yourself, your CDL, and everyone sharing the road.

Supported languages: English, Spanish, Russian, Chinese, Arabic, Portuguese, Korean, Turkish, Ukrainian, Uzbek.

Ratings and reviews

Very easy to use and explains each answer even if you got it wrong.

Very easy to Pass exam with this app. Thanks.

Many of the tests are the same. A single question was asked 2 or sometimes 3 times. I definitely do not recommend it. It is a terrible application.There are 480 questions in Airbrake Combination and General Knowledge. Only 5 questions in Airbrake are the same. If there was 0 points instead of 1, I would give that.
