Ouch! While you were on a roll there for a few questions, you didn’t pass this time. But I know this test, and I think you’ll pass next time. Really.
You may be asked to complete a conventional parallel parking maneuver into a parking space that is to the right of your vehicle. You should drive past the parking space before backing into it while bringing the rear of your vehicle as close to the rear of the space as possible. Your vehicle should be completely within the boundaries of the space.
On a school bus, the overhead inside rearview mirror is used to monitor passenger activity inside the bus.
Both systems in a dual air brake system share a single air compressor. If the air compressor is damaged, neither system will be able to operate properly.
If you have an Anti-Lock Braking System (ABS) equipped on only the tractor, only the trailer, or only one axle, you will still have more control over the vehicle when braking than you would without ABS. You should brake normally.
The aisles and stairwells of a bus should always be kept clear. Luggage and freight must be placed in a location that allows passengers to exit through any window or door in the event of an emergency.
A school bus driver does not have the authority to change the location of a school bus stop. Only appropriate school district officials can determine the locations of bus stops.
Containerized loads are generally used when freight is carried partway by rail or ship. Sealed materials cannot be inspected, but a driver should ensure that the containers do not exceed safe and legal weight limits.
In an air brake system, there are three different braking systems: a service brake system, a parking brake system, and an emergency brake system. The emergency brake system uses parts of both the parking and service brake systems.
The left and right side flat mirrors on the outside of a school bus should be adjusted so that the driver can see 200 feet (or four bus lengths) behind the bus.
On a bus designed to carry standing passengers, no passengers may stand in front of the rear of the driver's seat. Any such bus must have a line on the floor, or some other marking, that indicates where passengers may not stand. This is called a standee line.
A hazardous material will be placed into one of nine classes to explain the type of risks associated with the material.
Because air takes time to flow through the air lines to the brakes, air brakes cannot begin working instantly. There is often a brake lag of at least one-half of a second between the moment the brake pedal is pressed and the moment the brakes begin to work.
Anti-Lock Braking Systems (ABS) help prevent brake lockup when driving on slippery surfaces. If a driver brakes too hard on a slippery surface, ABS makes it easier for the driver to maintain control of their vehicle. A vehicle equipped with ABS should be driven and braked in the same way as a vehicle without ABS.
During a vehicle inspection test, you must ensure that all lug nuts are present, free of cracks and distortions, and showing no signs of looseness, such as rust trails or shiny threads. Verify that all bolt holes are free of cracks and distortions.
If the low pressure warning signal activates while you are driving, it is important that you safely exit the roadway as soon as possible and park your vehicle. If the air pressure gets too low, the brakes will no longer work well enough for you to stop safely.
All trucks, truck tractors, and buses must be equipped with emergency brakes and parking brakes. These brakes must be held by mechanical force.
A vehicle that is equipped with air brakes must also be equipped with a supply pressure gauge. This gauge tells the driver how much air pressure is in each of the vehicle's air tanks.
If used and maintained properly, air brakes are a safe and effective way to stop large, heavy vehicles.
Brakes are particularly prone to getting out out adjustment if they are hot. Use proper braking techniques to avoid letting your brakes overheat.
Vehicles with air brakes are required to be equipped with a low pressure warning device. A wig wag is a type of low air pressure warning device. This device drops a mechanical arm into the driver's view if the pressure in the tanks drops to a level between 55 and 75 psi.
