Sample CDL School Bus Endorsement practice questions

Try a few representative questions below. Each includes the correct answer and a short explanation — the same style you'll see in the full practice test.

1. Question 1Accident Procedures

   A school bus carrying 40 passengers is involved in a minor collision. The bus is still drivable, but one passenger has sustained a minor abrasion. According to Georgia CDL regulations, what is the driver's immediate responsibility following this incident?

   • A.Continue the route, as the injuries are minor and the bus is drivable.
   • B.Notify the school administration and dispatch, and remain at the scene until instructed otherwise or law enforcement arrives.(Correct)
   • C.Immediately drive the bus to the nearest police station to report the incident.
   • D.Have the passengers exit the bus and walk to the nearest safe location.

   Explanation

   Georgia CDL regulations require school bus drivers to notify their school administration and dispatch immediately after any accident, regardless of severity. The driver must remain at the scene to cooperate with authorities and ensure passenger safety, unless directed otherwise.

2. Question 2Railroad Crossings

   When approaching a railroad crossing with a standard flashing red signal system, what is the school bus driver's primary responsibility regarding the vehicle's brakes?

   • A.Release the parking brake to allow for a smoother acceleration after checking for trains.
   • B.Engage the parking brake only after the bus has come to a complete stop.
   • C.Apply the parking brake and the service brakes simultaneously before stopping.(Correct)
   • D.Apply the service brakes firmly once the bus is completely stopped.

   Explanation

   When approaching a railroad crossing, the driver must stop the bus 15 to 50 feet before the tracks. It is critical to apply both the parking brake and the service brakes simultaneously before coming to a complete stop to prevent any potential rolling.

3. Question 3Engine Mechanical Systems

   A school bus is equipped with a 6-cylinder engine with a displacement of 300 cubic inches. If the engine's compression ratio is 16:1, and the average compression pressure is 320 psi, what can be inferred about the engine's condition?

   • A.There might be a slight issue with one or more cylinders, potentially indicating worn piston rings or valves.(Correct)
   • B.The compression pressure is within the acceptable range for a gasoline engine of this size.
   • C.The compression pressure is significantly low, suggesting major internal engine wear or damage.
   • D.The engine is likely in excellent condition, with all cylinders performing optimally.

   Explanation

   While specific acceptable ranges vary by manufacturer, a 16:1 compression ratio typically aims for much higher pressures than 320 psi when new or in excellent condition. A drop of more than 10-15% between cylinders or below a certain threshold (often around 70-80% of the highest reading) indicates potential issues like worn rings, valve leaks, or head gasket problems.
