South Carolina CDL Hazmat: Placarding Test 2026

Placards are the highway's warning system, and the South Carolina hazmat placarding test makes certain you can display the right diamond every time. This CDL drill covers when placards are required, how the tables decide the count, which side of a diamond the class number belongs on, and how to placard a mixed hazardous materials load in 2026.

You will work through the difference between Table 1 and Table 2 materials, the 1,001-pound threshold logic, and the rule that placards go on all four sides of the vehicle. A HazMat endorsement driver in South Carolina who reads placards fluently can build a compliant rig and warn responders at a glance.

Question counts differ from state to state, so check your South Carolina CDL Manual for the exact figure on this section. Drill this placarding practice test until choosing and placing placards feels routine, then round out your hazmat prep with security and shipping papers.
