Chapter 3

Question 1

Visual Input

Answer 1

• Critical to vehicle controls
• Influence risk of being involved in crash
• Visual Lead, identify a path 20-30 sec ahead
• Pay attention to objects and hazards to the sides

Question 2

Visual Lead

Answer 2

• 20-30 Second ahead
• 2 blocks ahead
  1. Don’t walk signal hits 0,(light turns yellow
  2. Look in front, if everyone is braking or slowing
  3. Once u stop, look at rear view so no one crashes into you
  4. After stop, look in front (ground) see the bottom tire)

Question 3

Vehicle Operating Space

Answer 3

Path of Travel

Spare into which the driver can safely direct

Question 4

Visual Control Zone

Answer 4

Path of Travel or Visual Control Sone
- 12-15 sec
Following Distance (3-4 sec between vehicle and vehicle infront)

Question 5

Visual Referencing

Answer 5

• Helps manage space around your vehicle
• Precisely maneuver your vehicle
• Allows driver to relate to some part of vehicle to some part of roadway

Question 6

Q. The adhesion, car grip, between the tire and road surface

Answer 6

Traction

Question 7

Traction

Answer 7

Adhesion, friction, grip between tire and road surface

• Asphalt, gravel, brick less traction then concrete
• Driving on snow affects traction

Question 8

Q. Hydroplaning can occur at speeds as low as______ miles per hour

Answer 8

35 miles per hour

Question 9

Hydroplaning

Answer 9

Occurs when vehicles tire rises up on edge of water

1 Take off acceleration and get ready to steer

Question 10

Prevent Hydroplaning

Answer 10

1/12th inch of water
control vehicle speed
monitor depth of water
maintain proper tire(inflation, width, threads)

Question 11

Inertia

Answer 11

Force that keeps a vehicle straight ahead until acted upon by another force

Question 12

Momentum

Answer 12

p=my

How much motion an object has and is the product of mass x velocity

Question 13

How does gravity affect braking distance when driving downhill

Answer 13

a. Lengthens breaking distance

Speed, weight, center of gravity affect breaking distance

Question 14

Gravity

Answer 14

Invisible force that keeps on ground

Question 15

Q. If vehicle speed doubles, the distance needed to stop vehicle

Answer 15

Increases by 4( quadruples)

Question 16

Kinetic Energy

Answer 16

Amount of energy needed to propel a vehicle
Vehicle speed doubles from 20-40 mph
Vehicle speed needs 4 times the distance to stop
If u double speed, quadruple stoping distance

Question 17

Weight transfer

Answer 17

Turning right, left; accelerating, breaking

When breaking hard, weight of vehicle shift to front

Sudden inputs of accelerating. Braking, and steering can minimize traction and maximize weight shift.

(If back of cat does not come up, they are speeding though red/yellow light)
Front lifts when accelerating

passenger side is mode vulnerable when left turn

Question 18

Tire Contact Patch

Answer 18

Part of bottom of tire in contact with road

When turning right, contact on left side tire increases

Larger the contact patch, more traction

Smaller the patch less traction

Question 19

Q. The ____ a tires contact patch, the _____ traction the tire has with the road surface

Answer 19

d. b & c

larger, more
smaller, less

Question 20

Force of Impact

Answer 20

• Speed
• Weight
• Length of time between initial crash and vehicle stopped.

Question 21

3 Visual Input

Answer 21

Acceleration
Steering
Braking

Question 22

Best Traction

Answer 22

Slow and Smooth

Question 23

11 things why u need a greater following distance

Answer 23

1. Bad weather
2. Larger vehicle in front
3. Going up hill or down hill
4. Night time
5. tragic
6. freeway
7. novice driver
8. motorcycle
9. no following ambulance/ police (following trailer)
10. car with cargo (such as construction vehicle
11. narrow spaces

Question 24

where can u not change lanes

Answer 24

1. solid lines

2. middle of intersection
