Straight from the bank — answers highlighted, with the explanation underneath.

The 8-lamp warning system on a school bus consists of which combination of lamps?

  1. Four amber and four red alternately flashing lamps
  2. Eight red alternately flashing lamps
  3. Four amber and four green lamps
  4. Eight amber alternately flashing lamps
WhyThe 8-lamp system uses four amber (two front, two rear) and four red (two front, two rear) alternately flashing lamps; amber warns of an approaching stop and red signals loading/unloading.

Two technicians discuss the 8-lamp warning system. Technician A says the amber lamps warn motorists the bus is about to stop. Technician B says the red lamps mean the bus is loading or unloading and traffic must stop. Who is correct?

  1. Technician A only
  2. Technician B only
  3. Both Technicians A and B
  4. Neither Technician
WhyBoth are correct: amber is the advance warning that the bus is about to stop, and red means children are loading/unloading so traffic must stop.

The amber warning lamps operate normally, but the red lamps and stop arm never activate when the entrance door is opened. The MOST likely cause is:

  1. A faulty or misadjusted entrance-door switch
  2. Burned-out amber bulbs
  3. Low tire pressure
  4. A blown headlight fuse
WhyOn a door-actuated system, the door switch triggers the red lamps and stop arm; if amber works but red never activates on door opening, the door switch/circuit is the likely fault.
