1 . If a trailer's spring brakes do not release when you push the tractor air supply control, you should:
Drive normally without checking anything.
It is important that all of your vehicle's equipment is in proper working condition before you begin a trip. If a trailer's spring brakes do not release when you push in the tractor air supply control, you should make sure the air line connections are properly attached and sealed.
2 . The easiest way to recognize that your trailer has begun to skid is to:
Watch the jackknife warning light on the control panel.
The easiest way to spot a trailer skid is to use your mirrors. Any time you brake hard, check your mirrors to ensure that your trailer is still in its proper position.
3 . ____ are the cause of more than half of all accident-related truck driver deaths.
Pedestrians
More than half of all accident-related truck driver deaths are a result of truck rollovers. To help prevent a rollover, be sure to load cargo low to the ground and centered on your rig. Take corners slowly and carefully.
4 . When traveling more slowly than 40 mph, maintain at least ____ of following distance per every 10 feet of your vehicle.
Four seconds
At speeds below 40 mph, you should allow at least one second of following distance for every 10 feet of your vehicle. Follow the same formula when traveling at faster speeds, then add one additional second to your following distance. Remember that larger vehicles require more space to stop than smaller vehicles.
5 . A loss of air pressure in the emergency line will cause:
The emergency brakes to activate.
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 . A lightly-loaded combination vehicle will stop more slowly than a fully-loaded vehicle because:
The suspension springs only operate when a trailer reaches a minimum weight.
An empty combination vehicle will come to a complete stop more slowly than a fully-loaded vehicle. The stiff suspension springs and strong brakes will have lower traction on a light trailer than they would if the vehicle carried more weight.
7 . If a trailer is too high:
Coupling will be easier.
Before coupling together a tractor and a trailer, you should make sure the trailer is at the proper height. If the trailer is too low, the trailer nose may be damaged. If the trailer is too high, it may not be able to couple correctly.
