If you need to back up a bus without a look out, you should _______.

Answer: Set the parking brake, turn off the motor and take the keys with you and walk to the rear of the bus to determine whether the way is clear.

Backing a large vehicle like a bus without a lookout is inherently dangerous and should be avoided if possible. If absolutely necessary, the safest procedure is to first secure the bus by setting the parking brake, turning off the engine, and taking the keys. Then, the driver must walk to the rear of the bus to personally verify that the path is clear of obstacles, vehicles, and people before backing up slowly and cautiously.

Because students may drop an object near the bus during loading and unloading, you should _______.

Answer: Watch carefully as they enter and exit the bus.

The area around a school bus during loading and unloading is a high-risk zone for students. Because students might drop objects and bend down to retrieve them, or move unpredictably, it is crucial for the driver to watch them carefully as they enter and exit the bus. This constant vigilance helps prevent accidents, ensuring students remain visible and safe from the bus's wheels or other traffic.

Because of passing cars, the area ______ of the bus is always considered dangerous for school buses.

Answer: To the left

The area to the left of a school bus is particularly dangerous because of passing cars. While the bus is stopped with its stop arm extended, impatient drivers may illegally pass on the left, creating a significant hazard for students who might be crossing or approaching the bus. This makes the left side a critical area for drivers to monitor for potential conflicts and ensure student safety.

Once you have completed your school route, check for ________.

Answer: All of the listed answers.

After completing a school route, a thorough post-trip inspection is essential for several reasons. Drivers must check for open windows and doors, articles left on the bus, and most critically, sleeping students to ensure no child is left behind. Additionally, checking for mechanical or operational problems helps identify issues before the next trip, maintaining the bus's safety and readiness.

What is the maximum length of a bus' tail swing?

Answer: 3 ft.

When a bus turns, the rear portion of the vehicle swings out in the opposite direction of the turn, a phenomenon known as 'tail swing.' This tail swing can be up to 3 feet long, posing a significant hazard to pedestrians, parked cars, or objects near the bus's rear. Drivers must be aware of this dimension to avoid collisions when maneuvering in tight spaces and ensure safety.

You should never back a school bus when _________.

Answer: Students are outside of the bus.

Backing a school bus is one of the most dangerous maneuvers, and it is absolutely prohibited when students are outside the bus. The risk of not seeing a child in mirrors or blind spots is too high, potentially leading to tragic accidents. Drivers must ensure all students are safely inside the bus or completely clear of the danger zone before initiating any backing movement.

Students should evacuate the bus when ________.

Answer: All of the listed answers.

Student evacuation from a school bus is a critical safety procedure reserved for situations of immediate danger. These include the bus being on fire, stalled on a railroad-highway crossing where a collision is imminent, or any other situation presenting an immediate threat of collision or harm. In such emergencies, rapid and orderly evacuation is paramount to ensure student safety.

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

Answer: 3

The tail swing of a school bus refers to the distance the rear of the bus moves sideways in the opposite direction of a turn. This movement can extend up to 3 feet, creating a potential hazard for anything in its path. Bus drivers must always account for this tail swing to prevent striking objects or pedestrians during turns and ensure safe maneuvering.

When you back up your vehicle, you should assign someone as a lookout, who could warn you of ________.

Answer: All of the listed answers.

When backing a large vehicle like a bus, a lookout is invaluable for safety. A properly positioned lookout can provide crucial warnings about obstacles, approaching persons, and other vehicles that may be in the driver's blind spots. Their assistance significantly reduces the risk of collisions and ensures a safer backing maneuver, especially in crowded or complex environments.

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

Answer: Overhead inside rearview mirrors.

On buses, the overhead inside rearview mirrors are typically mounted directly above the windshield on the driver's side. These mirrors are crucial for monitoring passengers inside the bus, especially students, and for observing the general activity within the passenger compartment. They provide the driver with an important view of the interior without requiring them to turn their head significantly, aiding in student supervision.

How many feet can the danger zone around a school bus extend?

Answer: 30 ft.

The danger zone around a school bus is the area where children are most at risk of being hit, either by the bus itself or by other vehicles. This zone extends at least 10 feet in front of, to the sides of, and to the rear of the bus, but it is generally considered to extend up to 30 feet. Drivers must be extremely vigilant when children are in this area, especially during loading and unloading, to prevent accidents.

What can help you maintain student safety during an emergency?

Answer: Keeping the students on the bus.

In many emergency situations, especially those not involving immediate threats like fire or collision, keeping students on the bus can be the safest course of action. The bus provides a controlled environment and protection from external hazards, such as traffic or severe weather. Evacuation should only be performed when the danger inside the bus outweighs the danger outside, following established protocols.

When checking your hydraulic brakes, pump the brake pedal three times and make sure you hold it down for ______. The brake pedal should not depress during this time.

Answer: 5 seconds.

When checking hydraulic brakes during a pre-trip inspection, drivers must pump the brake pedal three times to build pressure, then hold it down firmly for five seconds. During this time, the pedal should not depress more than slightly, indicating that there are no significant leaks in the hydraulic system. This test is crucial for ensuring the brakes are functioning correctly and safely before driving.

If you are having difficulty driving in high winds who should you contact?

Answer: Your dispatcher.

If a bus driver is experiencing difficulty driving in high winds or other adverse weather conditions, they should immediately contact their dispatcher. The dispatcher can provide guidance, authorize route changes, or arrange for assistance, ensuring the safety of both the driver and passengers. It's crucial to communicate such challenges to the appropriate authority for support and decision-making.
