School Bus Endorsement S Flashcards

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

Answer: All of the listed answers.

A thorough pre-trip inspection is essential for safe operation of any commercial vehicle. This includes verifying that all critical safety systems are in proper working order. Service brakes, the parking brake, the steering mechanism, and lights and reflectors are all fundamental components that directly impact the vehicle's ability to stop, control, and be seen, making their inspection mandatory before driving.

Occasionally, you may have a drunk or disruptive passenger on your bus. In this instance, you should ________.

Answer: Discharge the passenger at the safest spot, which may be the next scheduled stop

The primary concern when dealing with a drunk or disruptive passenger is the safety of all individuals on the bus, including the driver. While removing the passenger is necessary, it must be done responsibly and safely. Discharging them at the next scheduled stop or another safe, well-lit location ensures they are not left in a dangerous situation, balancing the need for removal with passenger welfare.

Which of the following is a good indicator that you are driving your bus too fast for a banked curve?

Answer: If your bus leans toward the outside on a banked curve.

Banked curves are designed to help vehicles maintain stability at certain speeds by using the road's slope. If your bus leans toward the outside of a banked curve, it indicates that the centrifugal force generated by your speed is overcoming the banking angle. This is a clear sign that you are driving too fast for the curve and risk losing control of the vehicle.

Bus drivers cannot carry more than _______ lbs. of solid Class 6 poisons.

Answer: 100

Federal regulations specifically limit the amount of certain hazardous materials that can be transported on a passenger-carrying vehicle like a bus. For solid Class 6 poisons, bus drivers are restricted to carrying no more than 100 pounds. This regulation is in place to minimize the risk to passengers and the public in the event of an incident involving these dangerous substances.

The brake-door interlocks _________.

Answer: Apply the brakes and hold the throttle in idle position when the rear door is open.

Brake-door interlocks are a crucial safety feature on buses, especially school buses. This system is designed to prevent the bus from moving while passengers are boarding or exiting through the rear door. By automatically applying the brakes and holding the throttle at idle, it ensures the vehicle remains stationary, greatly reducing the risk of accidents.

Which mirrors are located below the outside flat mirrors?

Answer: The outside convex mirrors.

On many commercial vehicles, including buses, the outside flat mirrors provide a true, but limited, view of the rear and sides. Below these flat mirrors, convex mirrors are often positioned to offer a wider-angle view. These convex mirrors help drivers see blind spots along the sides of the vehicle that the flat mirrors cannot cover.

A safe place to evacuate students will generally be at least 100 ft. off the road except when ________.

Answer: There is a risk of spilled hazardous materials.

While 100 feet off the road is a general guideline for evacuating students to a safe area, this distance is insufficient if hazardous materials are involved. In the event of a hazardous material spill, the safe evacuation distance must be significantly greater, often hundreds or thousands of feet, depending on the material and wind conditions. The primary goal is to move students far enough away to avoid exposure to dangerous fumes or substances.

If a student drops an object while entering your bus, as the bus driver, you should tell the students to _______.

Answer: All of the listed answers.

When a student drops an object while boarding, safety is paramount. Students should be instructed to move to a safe area away from the bus's danger zones (like the wheels or under the bus). They should also attempt to get the driver's attention to retrieve the object safely, or, if retrieval is unsafe, be prepared to leave the object behind. Prioritizing student safety over retrieving an item is crucial.

Where are the outside left and right side flat mirrors located?

Answer: Mounted at the left and right front corners of the bus at the side or front of the windshield.

The outside left and right side flat mirrors are primary mirrors for bus drivers, providing a direct view of traffic to the sides and rear. They are typically mounted prominently at the front corners of the bus, either on the side or near the front of the windshield. This placement allows the driver to easily monitor traffic conditions and blind spots alongside the vehicle.

You should never back a school bus when _________.

Answer: Students are outside of the bus.

Backing a school bus is inherently dangerous due to large blind spots, and the risk is significantly amplified when students are outside the bus. There is an extreme danger of not seeing a child, leading to severe injury or fatality. Therefore, school bus drivers must never back the bus when students are outside, prioritizing their safety above all else.

When securing the bus during an evacuation, remember to ________.

Answer: All of the listed answers.

During an emergency evacuation, it is critical to properly secure the bus to prevent it from moving or posing further hazards. This involves placing the transmission in Park, setting the parking brakes to ensure stability, shutting off the engine to eliminate potential fire risks, and activating hazard-warning lights to alert other motorists to the stopped vehicle and emergency situation. All these steps are vital for safety.

You should ensure the outside crossover mirrors are adjusted properly so you can see ________.

Answer: All of the listed answers.

Outside crossover mirrors are specifically designed to provide the driver with a comprehensive view of the critical "danger zones" around the front of the bus. Proper adjustment ensures visibility of the entire area in front of the bus, from the bumper at ground level to where direct vision begins, as well as the area from the front of the bus to the service door, and the right and left front tires touching the ground. This minimizes blind spots and enhances safety, especially when students are near the bus.

The outside left and right side convex mirrors are used to _______.

Answer: Monitor the left and right sides at a wide angle.

Convex mirrors are curved outwards, which allows them to provide a much wider field of view compared to flat mirrors. On a bus, the outside left and right side convex mirrors are specifically used to monitor the sides of the vehicle at a wide angle. This helps drivers see objects and vehicles in their blind spots, enhancing overall situational awareness and safety.

The antilock braking system _______.

Answer: Only activates when the wheels are about to lock up.

The Antilock Braking System (ABS) is a safety feature designed to prevent the wheels from locking up during hard braking. It does not improve the vehicle's normal braking ability or shorten stopping distances. Instead, ABS activates only when it detects a wheel is about to lock, modulating brake pressure to allow the driver to maintain steering control and prevent skidding, especially on slippery surfaces.

What color are the traffic control devices on an active railroad-highway crossing?

Answer: Yellow

Traffic control devices at active railroad-highway crossings utilize specific colors to convey warnings and instructions. Warning signs, such as the round "Railroad Crossing" sign, are typically yellow with black lettering. Active warning signals, like flashing lights, are red to indicate an approaching train and that drivers must stop. Therefore, both yellow (for signs) and red (for lights) are colors associated with these devices.

Buses built before _____ have been voluntarily equipped with ABS.

Answer: 1998

While Antilock Braking Systems (ABS) became mandatory for most new commercial vehicles, including buses, after a certain date, some manufacturers voluntarily equipped their vehicles with ABS prior to this requirement. Specifically, buses built before March 1, 1998, may have been voluntarily equipped with ABS, offering enhanced safety features before they were federally mandated.

During an emergency, you first need to _______.

Answer: Recognize the type of hazard.

In any emergency situation, the very first step is to accurately assess and recognize the type of hazard present. Understanding whether it's a fire, a collision, a hazardous material spill, or another threat dictates the appropriate response, such as whether to evacuate immediately, shelter in place, or call for specific emergency services. This initial assessment is crucial for making informed and effective decisions.

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 electrical traffic control devices that regulate traffic flow when a train is approaching. These devices typically include flashing lights, bells, and/or automatic gates. Their purpose is to provide clear warnings and physically prevent vehicles from entering the crossing when it is unsafe, unlike passive crossings which only have signs.

Once all the students have boarded, and you have accounted for each student, close the doors. Then before entering traffic flow and continuing your route, you should __________.

Answer: All of the listed answers.

After all students have boarded, are accounted for, and the doors are closed, a bus driver must ensure the environment is safe before re-entering traffic. This includes allowing any congested traffic to disperse, which provides a clear and safe path for the bus to merge. While "open the bus doors" is contradictory and "call parents" is not a universal immediate step, the option "All of the listed answers" emphasizes a comprehensive approach to safety and readiness before continuing the route, ensuring all necessary precautions are considered.

During an emergency, remember that you can possibly evacuate through _______.

Answer: All of the listed answers.

In an emergency, it's vital for bus drivers to be aware of all available evacuation routes to ensure students can exit safely. Besides the primary service door, buses are equipped with multiple emergency exits. These typically include a rear door, side emergency doors, emergency windows, and sometimes roof hatches, providing various options for evacuation depending on the nature and location of the emergency.
