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 49 CFR 391.11 — over 13,000 drivers have already been placed out of service for failing the two-step ELP assessment.

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.

Start today — download CDL Help and earn your CDL with confidence.

Ratings and reviews

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.

I passed! Great app!

I am trying to cancel the subscription, their link to cancel it doesnt work, they keep charging my card. I tried for couple of times. And managed to cancel it thru google subsctiptions.
