Question 1: Why should you back toward the driver's side?
Answer:
So you can see better. Backing towards the right side is dangerous because you can't see as well. If you back towards the driver's side, you can look out the side window. Use driver's side backing-even if it means going around the block to put your vehicle in this position. The safety is worth it.
Question 2: What are the two ways to know when to shift?
Answer:
- Use engine speed (rpm)
- Use road speed(mph)
Question 3: Retarders keep you from skidding when the road is slippery. True or false
Answer:
False When your drive tires have poor traction, the retarder may cause them to skid. Therefore you should turn the retarder off whenever the road is wet, icy, or snow covered.
Question 4: When should you downshift automatic transmissions?
Answer:
You can select a low range to get greater engine braking when going down grades. The lower the ranges prevent the transmission from shifting up beyond the selected gear (unless the governor rom is exceeded). It is very important to use this braking when going down grades.
Question 5: When braking, why is it important to use a helper?
Answer:
There are blind spots you can't see. That's why a helper is important. The helper should stand near the back of the vehicle where you can see the helper.
Question 6: What are the two special conditions where you should downshift?
Answer:

- Before entering a curve.
? slow down to a safe speed and downshift to the right gear before entering the curve. This lets you use some power through the curve to help the vehicle be more stable while turning. It also allows you to speed up as soon as you are out of the curve.Question 7: If stopped on a hill, how can you start moving without rolling back?
Answer:
Don't roll back when when you start. You may hit someone behind you, partly engage the clutch before you take your right foot of the brake. Put on the parking brake whenever necessary to keep from rolling back. On a tractor-trailer equipped with a trailer brake hand valve, the hand valve can be applied to keep you from rolling. Speed up very gradually so the vehicle does not jerk. Rough acceleration can damage the coupling.Question 8: What's the most important hand signal that you and the helper should agree on?
Answer:
Stop
