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.
