CDL School Bus Endorsement S Practice Test 5

Question 1

Inspect your bus _____.

Accepted Answer

At the beginning and the end of each shift.

Answer

To ensure safety and compliance, bus drivers are required to inspect their vehicle thoroughly at the beginning and end of each shift. The pre-trip inspection confirms the bus is safe to operate, while the post-trip inspection helps identify any issues that developed during the shift, allowing for timely repairs before the next use.

Question 2

Which of the following should you ensure is in working condition before driving?

Accepted Answer

All of the listed answers.

Answer

Before operating any commercial vehicle, especially one carrying passengers, it is critical to ensure all essential safety systems are fully functional. This includes the service brakes for stopping, the parking brake for securing the vehicle, lights and reflectors for visibility, and the steering mechanism for control. Failure of any of these components can lead to serious accidents.

Question 3

Which of the following parts of your bus needs to be in safe working condition before driving?

Accepted Answer

All of the listed answers.

Answer

For the safety of passengers, especially in a bus, all components related to emergency egress, passenger movement, and communication must be in safe working condition. This includes functional emergency exit handles, secure handholds and railings for stability, and operational signaling devices to communicate with other road users and students. Therefore, all listed items are crucial for safe operation.

Question 4

While driving a bus, how many feet before a railroad crossing should you stop?

Accepted Answer

15 to 50 ft.

Answer

Federal regulations and CDL guidelines mandate that commercial vehicles, including buses, stop at railroad crossings. The required stopping distance is between 15 and 50 feet from the nearest rail. This range provides sufficient space to clear the tracks if another vehicle stops behind, while also allowing the driver a clear view of the tracks in both directions for safety.

Question 5

The interlock applies the brakes and holds the throttle in idle position. The interlock releases the brakes when ______.

Accepted Answer

When you close the rear door.

Answer

The interlock system on a bus is a crucial safety feature designed to prevent the bus from moving while the rear door is open. It applies the brakes and holds the throttle at an idle position. The system will only release the brakes and allow the bus to be driven once the rear door is fully closed, ensuring passenger safety during loading and unloading.
