A vehicle inspection should be completed in the same order every time. This will make it easier for you to learn all of the steps and will make it less likely that you will forget to check something.
9 . If a tire fails, you should:
Wave your arms at other drivers.
Using the brakes after a tire failure could cause you to lose control of your vehicle. Unless you're about to hit something, stay off of the brake until the vehicle has slowed sufficiently.

Allow the turn signal to stay on long after the turn has been completed.

12 . How does doubling your speed from 20 mph to 40 mph affect your vehicle's braking distance?
Increasing your vehicle's speed will increase your vehicle's striking power and braking distance. Doubling your vehicle's speed from 20 to 40 mph will quadruple its braking distance.

Cracked to allow for an improved grip.
To maintain proper control of your vehicle, the steering wheel should be held firmly with both hands. Your hands should be positioned on opposite sides of the wheel.
