Texas CDL Hazmat: Placarding Test 2026

Placards are the first thing a responder sees, and the Texas CDL hazmat placarding test asks whether you can decide which ones belong on your trailer and where they hang. This 2026 placarding practice test for Texas drivers covers the two placard tables, the 1,001 pound aggregate threshold that pulls Table 2 materials into the rules, and the materials that require placards at any quantity at all.

You will work through placement on all four sides, keeping the diamonds clean, readable, and clear of dirt or ladders, and matching the placard to the material actually in the load rather than to what was hauled last week. Items also cover the DANGEROUS placard for mixed loads and the situations where that shortcut is not allowed, plus your duty to remove placards once the hazardous freight is gone. Petrochemical freight moving out of the Houston ship channel makes this everyday work for Texas CDL drivers.

The exact hazmat question count is published in your Texas CDL Manual, so verify it there. Practice this Texas placarding drill until table lookups take seconds.
