Connecticut CDL School Bus: Lights Test 2026

The flashing lights and stop arm turn a school bus into a rolling traffic signal, and the Connecticut CDL school bus lights and stop arm test confirms you use them correctly for the 2026 S endorsement. This Connecticut CDL drill covers the yellow warning phase, the red loading phase, and when the stop arm must extend.

You will work through activating the amber lights ahead of a stop, switching to red as children cross, and understanding what other drivers are legally required to do when your signals are on. The Connecticut CDL Manual explains this sequence, and the Connecticut DMV holds school bus drivers responsible for running it the same way at every stop.

The school bus knowledge test has its own length, listed in your Connecticut Commercial Driver's Manual, so verify it there rather than assuming. Repeat this lights and stop arm test until the warning-to-red sequence is second nature and your signals always tell the road exactly what is happening.
