Texas CDL School Bus: Lights Test 2026

The warning light system is the school bus driver's main tool for controlling traffic, and the Texas CDL school bus lights and stop arm test checks that you use it correctly every time. This 2026 school bus endorsement drill for Texas covers activating the alternating amber lights far enough ahead of the stop, switching to the red flashing lights with the stop arm extended once you are stopped, and turning everything off before you pull back into traffic.

Questions also cover the crossing gate on buses that carry one, timing so the ambers are not on so long that drivers ignore them, what to do when a motorist illegally passes a bus displaying red lights and a stop arm, and why the system never substitutes for looking. Texas drivers pass stopped school buses more often than anyone would like, so the lights buy attention rather than guarantee safety.

Your Texas CDL Manual gives the exact S endorsement question count. Practice this Texas school bus stop arm drill until the light sequence is muscle memory.
