School Bus Endorsement S Flashcards

Inspect your bus _____.

Answer: At the beginning and the end of each shift.

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.

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

Answer: All of the listed answers.

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.

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

Answer: All of the listed answers.

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.

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

Answer: 15 to 50 ft.

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.

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

Answer: When you close the rear door.

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.

Why should you bring your school bus to a full stop with the front bumper at least 10 ft. away from the designated stop?

Answer: Allows you to have a better view of the students as they are walking to the bus.

Stopping the school bus with the front bumper at least 10 feet away from the designated stop provides the driver with a significantly improved field of vision. This increased distance allows the driver to better observe students approaching the bus from various angles, particularly those in the 'danger zones' around the front of the bus, thereby enhancing safety during student loading.

When should you turn on your right turn signal indicator before pulling over?

Answer: 100-300 ft.

Activating your turn signal 100-300 feet before pulling over provides ample warning to other drivers and pedestrians of your intentions. This allows them sufficient time to react and adjust their speed or position, preventing sudden maneuvers and reducing the risk of collisions. This is especially important for large vehicles like buses, which require more space and time to maneuver.

When the outside left flat and right mirrors are adjusted properly, you should be able to see how many feet behind the bus?

Answer: 200 ft.

Properly adjusted outside flat mirrors are essential for maintaining situational awareness around a bus. When correctly set, these mirrors should provide the driver with a clear view of at least 200 feet behind the vehicle. This extensive rearward visibility allows the driver to monitor traffic, identify potential hazards, and safely execute maneuvers such as lane changes or turns.

To prevent accidents, tell your students to _______.

Answer: All of the listed answers.

Student safety is paramount when operating a school bus, and clear instructions are vital to prevent accidents. Telling students to get the driver's attention before retrieving objects, moving to designated safety zones, and leaving dropped objects behind if unsafe, collectively minimizes risks around the bus. These actions prevent students from entering dangerous blind spots or paths of the bus.

How should the outside crossover mirrors be adjusted?

Answer: All of the listed answers.

Crossover mirrors are critical for eliminating blind spots directly in front of and immediately to the sides of the bus, areas where students are often present. They must be adjusted to provide a continuous view from the front bumper at ground level to where direct vision is possible, and also cover the areas from the front of the bus to the service door, including the left and right front tires. This comprehensive adjustment ensures maximum visibility of students and obstacles.

An active railroad-highway crossing _________.

Answer: Has a traffic control device installed at the crossing to regulate traffic.

An active railroad-highway crossing is distinguished by the presence of mechanical or electronic traffic control devices. These devices, such as flashing lights, bells, or automatic gates, are installed at the crossing specifically to warn drivers of an approaching train and regulate traffic flow, providing a higher level of safety compared to passive crossings.

________ is the first and most important thing you should do during an emergency.

Answer: Recognizing the type of hazard.

In any emergency situation, the first and most crucial step is to quickly and accurately recognize the type of hazard present. This initial assessment dictates all subsequent actions, such as whether to evacuate the bus, how to protect students, or what emergency services to contact. A correct hazard assessment ensures the most appropriate and effective response to mitigate danger.

The antilock braking system _______.

Answer: All of the listed answers.

The Antilock Braking System (ABS) is a significant safety enhancement that works in conjunction with your normal brakes. Its primary function is to prevent wheel lock-up during hard brake applications, allowing the driver to maintain steering control. ABS does not increase or decrease your normal braking ability but optimizes it for control, activating only when the wheels are about to lock up.

It's important to remember ABS will not prevent jackknifes or skids caused by __________.

Answer: Spinning the driver wheels and/or going too fast in a turn.

While ABS is highly effective at preventing brake-induced skids by keeping wheels from locking, it cannot prevent jackknifes or skids caused by driver error or excessive speed. Specifically, spinning the drive wheels due to over-acceleration on slippery surfaces or going too fast into a turn can still lead to a loss of control, as ABS primarily manages braking force, not traction from acceleration or centrifugal force.

The ________ are mounted directly above the windshields on driver's side of buses.

Answer: Overhead inside rearview mirrors.

The overhead inside rearview mirrors are strategically mounted directly above the windshields on the driver's side of buses. This placement provides the driver with a clear and comprehensive view of the entire passenger compartment. This allows the driver to monitor student behavior and ensure safety without significantly diverting their attention from the road ahead.

The computerized system that keeps your wheels from locking up during hard brake applications is ________.

Answer: The antilock braking system.

The Antilock Braking System (ABS) is a sophisticated computerized safety system designed to prevent the wheels of a vehicle from locking up during sudden or hard braking. By rapidly modulating brake pressure to each wheel, ABS allows the driver to maintain steering control and reduce stopping distances, especially on slippery surfaces.

Generally, the blind spot behind the bus extends in between what range?

Answer: 50- 150 ft.

Due to their large size and design, buses have significant blind spots, particularly directly behind the vehicle. This blind spot can generally extend anywhere from 50 to 150 feet behind the bus. Drivers must be acutely aware of this area and use all available mirrors and caution to ensure no one is in this zone before backing up or maneuvering.

Who requires that buses built after 2000 are equipped with ABS?

Answer: The Department of Transportation.

The Department of Transportation (DOT), through its regulatory arm, the National Highway Traffic Safety Administration (NHTSA), mandates safety features for commercial vehicles. To enhance safety and prevent accidents, the DOT requires all new buses manufactured after March 1, 2000, to be equipped with Antilock Braking Systems (ABS).

On newer vehicles with ABS, the malfunction lamp ________.

Answer: The malfunction lamp comes on at start-up for a bulb check and then goes out quickly.

On newer vehicles equipped with ABS, the malfunction lamp serves as an important indicator of the system's status. It is designed to illuminate briefly during vehicle start-up as a bulb check, confirming that the lamp itself is functional. If the ABS system is working correctly, the lamp should then turn off quickly; if it remains on, it indicates a system fault requiring attention.

School buses can have a tail swing up to how many feet?

Answer: 3

Due to their long wheelbase, school buses can experience significant 'tail swing' when making turns. The rear of the bus can swing out by as much as 3 feet in the opposite direction of the turn. Drivers must be extremely cautious and aware of this phenomenon to avoid hitting pedestrians, other vehicles, or objects during maneuvers.
