1. Which of the following is not a good way to reduce crashes when turning right?
Explanation
When making a right turn, avoid turning too wide to the left. If you must swing into another lane to complete the turn, you should keep the rear of your vehicle close to the curb. Leaving space to the right of your vehicle while turning right may indicate to other drivers that you are turning left, so they may attempt to pass you on your right.
2. If using a helper while backing a vehicle, where should they stand?
Explanation
If you use a helper while backing your vehicle, they should stand near the back of the vehicle in a place where they are visible to you. Before backing, work out a set of hand signals that both you and your helper understand. Agree on a signal for "stop."
3. ____ is a thin layer of ice that forms on road surfaces.
Explanation
Black ice is a thin layer of ice that is clear enough for the road surface to be seen through it. A road covered in black ice may look like it is merely wet. You should be very careful when temperatures are below freezing and the road looks wet.
4. The ____ trailer is the most likely to turn over if a driver takes a turn too quickly.
Explanation
When making a turn, be sure to steer gently and smoothly. Making a quick turn while pulling trailers is dangerous and can increase the risk of the last trailer rolling over.
5. What is a retarder?
Explanation
Retarders help to slow vehicles, reducing drivers' need to use brakes.
6. The trailer hand valve should be used:
Explanation
The trailer hand valve (also referred to as the "trolley valve" or "Johnson bar") works the trailer brakes and should be used only when testing them. Using the trailer hand valve while driving could result in a skid.
7. Broken suspension parts:
Explanation
The suspension system is responsible for supporting a vehicle, supporting its load, and keeping its axles in place. When inspecting your vehicle, check for damaged or missing spring hangers, spring leaves, shock absorbers, u-bolts, and frame members. Broken parts in the suspension system are extremely dangerous.
