1 . What is a drawback of retarders?
A retarder is a device that helps to slow a vehicle, reducing the need for a driver to use the brakes. However, these devices can be noisy and are not permitted everywhere.
2 . The air storage tanks:
The air storage tanks in an air brake system store compressed air to be used for braking. They hold enough air for the brakes to still be used several times if the compressor stops working.
3 . When should mirrors be adjusted?
The adjustment of your mirrors should be checked prior to the start of all trips. Adjust your mirrors as needed.
4 . A low air pressure warning signal should activate:
When tank pressure falls below 5 psi.
In an air brake system, a low air pressure warning signal must come on if air pressure in the tanks falls below 60 psi. This warning signal may come in the form of a light, a buzzer, or a wig wag.
5 . If the emergency air line loses pressure:
The emergency air line controls the emergency brakes on a combination vehicle. A loss of air pressure in the emergency line will cause the emergency trailer brakes to activate.
6 . When traveling through a work zone, you should:
Always observe posted speed limits for work zones. Slow down if road or weather conditions are adverse, and slow down even more if workers are on or near the road.
7 . If your vehicle is hydroplaning, you should:
If your vehicle begins to hydroplane, do not apply the brakes. Instead, slow down by releasing the accelerator and pushing in the clutch. This will help you to regain traction.
