Questions
Is this a subscription?
No. One payment of $19.99 unlocks the full 400-question bank on your device. There is nothing to cancel.
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.
