The Left-Turn Light and the Impatient Driver
You are in the left-turn lane at a signalized intersection with 44 students aboard, stopped at a red left-turn arrow. It is 7:35 a.m., dry, traffic moderate. Your pre-trip inspection this morning showed the left rear turn signal and brake light working, but the right rear turn signal was flickering intermittently; you noted it but did not have it repaired because the shop was closed. As you wait, a car behind you honks and edges into the lane beside you. The light turns green for through traffic, then the left-turn arrow turns green. You begin your turn and hear a pop, and the right rear turn signal stops working entirely. A crossing guard at the far corner is waving you through.
1. Should you have driven the bus this morning given the flickering right rear turn signal? Explain.
Read the worked answer
No, or at minimum not without authorization and documentation. A flickering turn signal is a known defect on a required lighting system. Pre-trip inspection rules require you to identify defects and report them; a bus with an inoperative or intermittent required light should not be placed in service until repaired or cleared by the shop. Driving it 'because the shop was closed' shifts the risk to 44 students. The correct action was to report the defect, document it, and either get it repaired, get a supervisor's written clearance, or use a different bus. The exam tests that 'noted but not repaired' is not the same as 'cleared.'
2. Now the right rear turn signal has failed mid-route. What do you do at the intersection and immediately after?
Read the worked answer
Complete the turn only when it is safe, using hand signals if needed to communicate, and do not stop in the intersection. After clearing the intersection, pull over at the first safe place, set the parking brake, and assess. With a required rear light out on a loaded bus, you should not continue the route as normal. Radio dispatch, report the defect and your location, and request a relief bus or authorization to proceed to the nearest safe point/school if the district permits. Keep students aboard and supervised. Document the failure and the time. The judgment: a mid-route lighting failure on a school bus is a serviceability issue, not a 'finish the route and mention it later' issue.
3. The crossing guard is waving you through and traffic behind is impatient. How does that affect your decision?
Read the worked answer
It does not change the safety decision. A crossing guard's wave is helpful but does not override your responsibility to verify the turn is clear and that your bus is serviceable. Impatient traffic behind you is not a reason to skip the pull-over and inspection. You complete the turn safely, then pull over as soon as it is safe to do so. If the guard's wave conflicts with what you see (e.g., a pedestrian or vehicle in the path), you wait. The exam point: external pressure and hand signals do not transfer responsibility for the bus and students away from you.
