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.
- Question 1Railroad Crossing Procedures
A school bus driver is approaching a railroad crossing with a posted speed limit of 45 mph. The driver observes a train approaching, and the distance to the crossing is such that it would take 25 seconds to reach the crossing at the current speed. If the train is traveling at 60 mph, and the crossing is 2000 feet away, what is the safest course of action regarding the bus's speed?
- A.Maintain current speed and prepare to stop if necessary.
- B.Slow down immediately to ensure a safe stop before the crossing.(Correct)
- C.Increase speed to clear the crossing before the train arrives.
- D.Honk the horn continuously to alert the train.
Explanation
The bus needs to stop before the crossing. The train is traveling at 60 mph (88 ft/sec) and the crossing is 2000 ft away. The train will reach the crossing in approximately 2000 ft / 88 ft/sec = 22.7 seconds. The bus driver needs at least 15 seconds to safely stop before the crossing. Therefore, the driver must slow down immediately to ensure a safe stop.
- Question 2Pre-Trip Inspection: Air Brakes
During a pre-trip inspection, a driver notices that the air pressure gauge is fluctuating between 90 psi and 110 psi while the engine is running. This indicates a potential issue with which system?
- A.The air brake system's governor or air compressor.(Correct)
- B.The engine cooling system.
- C.The hydraulic brake system.
- D.The electrical charging system.
Explanation
Fluctuations in air pressure indicate a problem with the system that supplies and regulates compressed air. The air governor controls the compressor, and a faulty governor or compressor can lead to unstable air pressure readings.
- Question 3Accident Reporting and Bus Out-of-Service
A school bus with a capacity of 66 passengers is involved in an incident where a student sustains a minor injury. According to Maryland regulations, what is the minimum number of days the bus must be taken out of service for mandatory inspection and reporting, regardless of the severity of the incident?
- A.3 days(Correct)
- B.5 days
- C.1 day
- D.7 days
Explanation
Maryland law mandates that a school bus involved in any accident resulting in injury to a passenger must be taken out of service for a minimum of three days for inspection and reporting, unless specifically cleared by law enforcement or a qualified mechanic.
