1
ONE PURPOSE OF A TREAD PATTERN ON A TIRE IS TO
LOOK IMPRESSIVE
REDUCE TIRE WEAR
REDUCE TRACTION
ALLOW WATER TO FLOW AWAY FROM THE TIRE
2
THE BEST PLACE TO ADJUST SPEED TO STEER THROUGH A CURVE IS
JUST BEFORE YOU LEAVE THE CURVE
AT THE CENTER OF THE CURVE
ABOUT HALFWAY THROUGH THE CURVE
BEFORE ENTERING THE CURVE
3
WHEN A VEHICLE'S SPEED TRIPLES, HOW MUCH MORE DISTANCE DOES IT NEED TO STOP?
ABOUT NINE TIMES THE DISTANCE
ABOUT 4 TIMES THE DISTANCE
ABOUT 3 TIMES THE DISTANCE
ABOUT DOUBLES THE DISTANCE
4
A LIGHTER VEHICLE
TAKES LONGER DISTANCE TO STOP
IS THE SAFEST OF ALL VEHICLES
CAN ACCELERATE AND STOP MORE QUICKLY THAN A LARGER VEHICLE
USES MORE KINETIC ENERGY TO STOP THAN A LARGER VEHICLE
5
DISTANCE VEHICLE TRAVELS AS YOU RESPOND TO A ROAD HAZARD
PERCEPTION DISTANCE
STOPPING DISTNCE
REACTION DISTANCE
BRAKING DISTANCE
6
DURING A COLLISSION, A DRIVER MOVES FORWARD AGAINST SAFETY BELT. WHAT CAUSES THE DRIVER TO MOVE FORWARD?
FRICTION
ENERGY OF MOTION
INERTIA
GRAVITY
7
DURING A COLLISION, A DRIVER MOVES FORWARD AGAINST A SAFETY BELT. WHAT CAUSES THE DRIVER TO MOVE FORWARD?
ENERGY OF MOTION
INERTIA
FRICTION
GRAVITY
8
WHEN A VEHICLE'S SPEED TRIPLES, HOW MUCH MORE DISTANCE DOES IT NEED TO STOP
THREE TIMES THE DISTANCE
DOUBLE THE DISTANCE
SIX TIMES THE DISTANCE
NINE TIMES THE DISTANCE
9
TOTAL STOPPING DISTANCE
TAKES FOR YOU TO BRAKE
TAKES FOR YOU TO REACT TO THE HAZARD
DISTANCE YOUR VEHICLE TRAVELS WHILE YOU MAKE A STOP
TAKES FOR YOU TO PERCEIVE A HAZARD
10
AN IMPORTANT FACTOR IN MAINTAINING TRACTION IS
OVERINFLATED TIRES
HAVING A BRAND NEW CAR
GOOD SHOCK ABSORBERS
A CLEAN CAR
11
WHEN A MOVING OBJECT HITS SOMETHING, WHAT IS THE MOST IMPORTANT FACTOR IN DETERMINING HOW HARD IT HITS?
GRAVITY
SPEED
TRACTION
DISTANCE TRAVELED
12
TOTAL STOPPING DISTANCE IS THE DISTANCE
YOUR VEHICLE TRAVELS WHILE YOU MAKE A STOP
IT TAKES FOR YOU TO BRAKE
IT TAKE FOR YOU TO PERCEIVE A HAZARD
13
A VEHICLE GOING UP A HILL WORKS
WITH THE FORCE OF GRAVITY
WITH CENTRIFUGAL FORCE
AGAINST THE FORCE OF GRAVITY
AGAINST CENTRIFUGAL FORCE
14
FACTORS THAT AFFECT TRACTION INCLUDE
VEHICLE AND ROAD CONDITION AND DRIVER ACTION
POLICE PRESENCE
LENGTH AND WIDTH OF THE ROAD
OIL, OIL FILTER, AND COOLANT
15
WHAT ARE THE MOST IMPORTANT PARTS OF THE CONTROL SYSTEM
BRAKES
THE STEERING WHEEL AND COLUMN
THE CLUTCH AND ACCELLERATOR
FOUR TIRES
16
THE CENTER OF GRAVITY OF A VEHICLE IS THAT POINT
ABOUT THREE FEET UNDER THE ROADWAY SURFACE
AROUND WHICH ALL WEIGHT IS EVENLY DISTRIBUTED
NEAR THE FRONT BUMPER
THAT IS FARTHEST FROM THE GROUND
17
ALWAYS SEARCHING AT LEAST 12-15 SECONDS AHEAD WILL IMPROVE YOUR
BRAKING TIME
STOPPING DISTANCE
REACTION TIME
PERCEPTION TIME
18
WHEN YOU SLOW FOR A TURN, SOME TRACTION IS USED TO SLOW, AND SOME IS
GAINED BY THE REAR TIRES
USED TO TURN
LOST FOREVER
MANUFACTURED
19
WHAT ARE THE MOST IMPORTANT PARTS OF THE CONTROL SYSTEM

FOUR WHEELS
20
WHEN YOU SLOW FOR A TURN, SOME TRACTION IS USED TO SLOW, AND SOME IS
GAINED BY THE REAR TIRES
MANUFACTURED
USED TO TURN
LOST FOREVER
21
THE HIGHER THE SPEED OF A VEHICLE, THE MORE
YOU WILL FEEL THE BUMPS IN THE PAVEMENT
YOU WILL LOSE TRACTION
MORE DISTANCE YOU NEED TO STOP
YOU WILL DRIFT SIDEWAYS
22
WHAT IS MOST LIKELY TO HAPPEN IN RAINY WEATHER?
PERCEPTION TIME DECREASES
PERCEPTION TIME INCREASES
REACTION TIME INCREASES
REACTION TIME DECREASES

OVERINFLATED
INFLATED JUST RIGHT
