1 . If you are being tailgated, you should:
If someone is following you too closely, you should open up the space in front of your vehicle to make it easier for the tailgater to pass. Speeding up is counterproductive because the other driver may just continue tailgating you at the higher speed, only increasing the danger.
2 . When backing with a trailer:
When backing, you should pull forward to reposition your vehicle whenever needed. Drift should be corrected immediately by turning the steering wheel in the direction of the drift.
3 . When should the trailer hand valve be used?
The trailer hand valve, also called the trolley valve or Johnson bar, is used to work the trailer brakes. It should be used only to test the brakes. Using it while a vehicle is in motion could cause a skid.
4 . How much water must be present for a vehicle to hydroplane?
Hydroplaning is an effect in which a vehicle's tires lose traction with the surface of the road and instead glide along a layer of water. There does not have to be much water on the road for this to occur.
5 . 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.
6 . Rims with welding repairs:
Wheels or rims that have had welding repairs should never be used.
