Unit 1 Exam 1 MC Study Guide

The adhesion, or grip, between the tires and the road surface is called

• gravity

• inertia

• traction

• kinetic energy

How does gravity impact braking distance when driving downhill?

• it lengthens braking distance

• has no effect on braking distance

• shortens braking distance

• decreases the vehicle's momentum

If a vehicle's speed doubles, the distance needed to stop the vehicle

• increases by two

• increases by three

• increases by four

• distance needed to stop doesn't change

To allow enough distance to stop when responding to hazardous objects or conditions, you should identify a planned path of travel how many seconds ahead?

• 2-4

• 12-15

• 20-30

• 50-60

What provides less traction when than driving on concrete?

• asphalt

• brick

• gravel

• all of the above

The top of the head restraint should be adjusted to a point

• slightly above your ears

• slightly below your ears

• at the base of the neck

• as high as the adjustment will allow

Which of the following hand positions allow for the best control when turning the steering wheel?

• 10 and 2

• 6 and 12

• 9 and 3

• 11 and 1

In vehicles equipped with a driver's side airbag, sitting closer than how many inches away from the steering wheel increase the risk of arm, neck and facial injuries in a crash?

• 10

• 12

• 14

• 16

How often should the pre-driving checks identified for approaching the vehicle and checking outside be performed?

• when you first buy the vehicle

• every so often (once a week)

• every time you drive

• only if something goes wrong

When approaching your vehicle parked at a curb, you should do what?

• approach from the rear of your vehicle, with your back to approaching the traffic

• approach from the front of your vehicle, facing oncoming traffic
