45 seconds.
When inspecting a vehicle with a dual air brake system, you should wait for air pressure to build from 85 to 100 psi in both the primary and secondary systems. This should take about 45 seconds.
16 . When checking your tires, which of the following is not something that should cause concern?
Dual tires that do not come into contact with each other
When inspecting your tires, be alert to a number of potential problems, including air pressure that is too low or too high; bad wear; cuts; tread separation; dual tires that come into contact with each other or with parts of the vehicle; mismatched tire sizes; radial and bias-ply tires used together; and cut or cracked valve stems. Additionally, verify that there are no regrooved, recapped, or retreaded tires on the front wheels of the bus.
17 . If carrying a heavy load that is slowing you down, you should:
Keep the vehicle in second gear.
The right lanes of a roadway are generally intended for vehicles traveling more slowly than surrounding traffic. If being slowed down by a heavy load, you should stay in the right lane.
18 . When approaching a railroad crossing, you should:
Never try to outdrive an approaching train.
Reduce your speed as you approach a railroad crossing. Remember that you will not necessarily be able to hear a train, and don't assume that signals will warn you of its approach. Never try to outdrive an approaching train at a railroad crossing.
19 . For safety purposes, when should you turn off a retarder?
When driving in heavy traffic
Retarders are mechanisms in some vehicles that help slow a vehicle and reduce the need for braking. However, using a retarder may cause wheels to skid when they have poor traction. Turn off retarders when traveling under wet, snowy, or icy conditions.
20 . To make it as safe as possible to leave a stop, you should park:
By backing into a parking space.
Backing can be dangerous, so avoid doing it whenever you can. If possible, park in such a way that allows you to pull forward to exit your parking space.
21 . To use the stab braking method in an emergency situation, you should:
Apply the emergency brake.
The stab braking method for emergency stops involves fully applying the brakes until they lock up. The brakes are then released until the wheels start rolling, then the process is repeated.
