Questions
Is everything really free?
Yes. The full 400-question bank, the 10-question diagnostic, and the mock exams are all free to use — no payment, no account, and no unlock code. Just open the practice page and start.
Are these the real test questions?
No. They are original practice questions based on the official CDL handbook (Section 9 — Hazardous Materials) and cross-checked against 49 CFR. Each question cites its source so you can confirm the rule in the handbook yourself.
Do I need an account?
No. Everything runs in your browser, and your wrong-answer notebook and progress are stored on your own device — so use the device you'll study on, and they'll be there when you come back.
