Texas CDL Hazmat Practice Test 1: what to expect and what trips drivers up

This free Texas hazmat practice test is the place to start on the H endorsement. Written for 2026, this CDL hazmat practice test for Texas drivers pulls from the same knowledge areas the real hazardous materials endorsement test draws on: hazard classes, placarding tables, shipping papers, marking and labeling, loading rules, security awareness, and emergency response. It is a full DOT hazmat practice test rehearsal you can take right now, with no account and no payment.

The H endorsement matters enormously in Texas. Permian Basin crude, oilfield chemicals, and the petrochemical stream running out of the Port of Houston all move behind placards, and carriers pay for drivers who hold the credential. Along with passing the written exam at Texas DPS, you complete a TSA security threat assessment with fingerprinting, so plan the timeline before you need the endorsement on a dispatch.

Question counts for endorsement exams are set state by state, so look up the exact figure in your Texas CDL Manual instead of trusting a forum post. Score consistently on this Texas hazmat practice test, then move to the harder drills.

Keep going:

Every question traces back to the Texas CDL Manual - skim the right-of-way and signs chapters before your retake.
