Oklahoma CDL School Bus: Lights Test 2026

The flashing lights and extended stop arm are a school bus driver's most powerful safety tools, and this Oklahoma school bus lights and stop arm test makes sure you use them correctly. The S endorsement requires precise timing of your warning system, and this 2026 Oklahoma CDL drill nails down exactly when each signal comes on.

You will practice when to activate the yellow warning lights, when the red lights and stop arm come out, how far ahead to begin signaling, and what to do when other drivers ignore them. Getting this sequence right is what stops traffic and creates a safe path for children.

Endorsement tests differ in length from one state to the next, so confirm the number of questions in your Oklahoma Commercial Driver License Manual before you test. Keep running this lights and stop arm set until the timing is automatic, and your student stops will be textbook every time.
