1 . Before beginning a trip, you should:

2 . A combination vehicle has ____ air line(s).
Every combination vehicle has two air lines: the service line and the emergency line.
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 . When traveling more slowly than 40 mph, maintain at least ____ of following distance per every 10 feet of your vehicle.
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 . If you need to back your trailer but cannot back up in a straight path, you should:
If you need to back your trailer but cannot back up in a straight path, you should back on a curved path toward the driver's side of the vehicle. This will permit you the best possible visibility while backing.
6 . When driving with trailers, you should:
To reduce the risk of tipping over when driving with a trailer, you should steer gently and smoothly. Avoid making sudden movements.
7 . When lightly loaded, combination vehicles:
When a combination vehicle is lightly loaded, it may have poor traction. It is very easy for wheels to lock up on lightly-loaded vehicles when they are being stopped.
