Question 1

Anti-lock brake system

Answer 1

Computer controlled brake system designed to prevent wheel lock-up during heavy braking

Question 2

Apex (or low side)

Answer 2

The lowest portion of a vehicle’s path through a curve

Question 3

Balance hand position

Answer 3

Maintaining a wide grip on a vehicle’s steering wheel

Question 4

Brake fade

Answer 4

The loss of braking efficiency normally due to heat build-up resulting from excessive use of brake

Question 5

Counter steer

Answer 5

Turning the front wheels of a vehicle in the direction the rear of the vehicle is sliding

Question 6

Front end swing

Answer 6

The action of the front end of the vehicle when backing: the front end swings to the right when backing to the left; the front end swings to the left when backing to the right.

Question 7

Oversteer

Answer 7

The characteristic of a vehicle to tighten its turning radius as the rear end slips or skids towards the outside of a curve

Question 8

Rear end cheat (rear wheel cheat)

Answer 8

When turning left, a vehicle’s rear tires track to the left of the front tires. When a vehicle is turning right, the rear tires track to the right of the front tires

Question 9

Rolling friction

Answer 9

The front wheels of a vehicle must be rolling, thereby creating rolling friction, in order to steer the vehicle

Question 10

Slip angel

Answer 10

The turning radius of a vehicle becomes larger as the contact patch of each tire is distorted by increasing cornering force

Question 11

Threshold braking

Answer 11

Application of braking force to the point just prior to wheel lock up. This braking technique is more efficient at slowing a vehicle than locked wheel braking.

Question 12

Time spatial judgment (closure rate judgment)

Answer 12

Judging the proper rate of deceleration necessary to successfully negotiate a curve or to avoid a hazard

Question 13

Understeer

Answer 13

The tendency for a vehicle to continue in a straight line and resist turning from a direct course of travel

Question 14

Visual horizon

Answer 14

The area distance viewed by the driver of a vehicle when looking ahead. High visual horizon is always optimal

Question 15

Longitudinal weight transfer

Answer 15

Weight transfer to the front axle of a vehicle caused by braking or deceleration

Question 16

Lateral weight transfer

Answer 16

Weight transfer of the front axle to the left when turning the vehicle to the right, and weight transfer of the front axle to the right when turning the vehicle to the left.
