29 . When pulled over to the side of the road, you should:
When stopped on the side of the road, be sure to turn on your vehicle's four-way emergency flashers, especially during times of lowered visibility. Place warning devices within 10 minutes of being stopped.
30 . If planning to back a vehicle where there may be overhanging objects, a driver should:
Because you can't see everything behind you, driving in reverse is always dangerous and should be done only when necessary. Before backing into an area, you should exit your vehicle and inspect the path of travel to check for potential hazards, especially overhanging objects that would otherwise be difficult to spot in a mirror.
31 . When you need to stop in an emergency, you should:
Expect your vehicle to slow down more quickly than usual.
If you need to make an emergency stop, you can use either the controlled braking method or the stab braking method. It's important to brake in a way that keeps your vehicle traveling in a straight line while still allowing you to turn, if necessary.
32 . If using the spring brakes while hauling a heavy load, a complete stop will:
Damage the brakes.
Spring brakes will activate in a vehicle with air brakes if the pressure in the air system becomes too low. A heavily loaded vehicle will take a long time to stop when using only the spring brakes because the spring brakes do not work on all axles.
33 . If you identify a large box in your lane on the road ahead, you should:
Swerve into another lane of traffic.
Slow down and be very careful if you see foreign objects in your lane. Remember that even something that seems relatively light and harmless, like a cardboard box, could contain harder or heavier items that could cause damage to your vehicle.
34 . The two indicators that determine when you should upshift are:
Oil pressure and air brake pressure.
There are two indicators that determine when you need to shift into a higher gear. One indicator is the engine speed (rpm). You should read your vehicle's manual to learn its rpm range and shift up when you reach the top of that range. The other indicator is road speed (mph). You should learn which speeds each gear can accommodate, then keep an eye on the speedometer and shift up as needed.
35 . When inspecting your tires, you do not want to find:
There should be at least 4/32 of an inch of tread depth in every major groove on front tires and 2/32 of an inch on other tires. Valve stems should not be cut or cracked. Tire sizes should not be mismatched.
