Terms in this set (64)
A small vehicle
can accelerate and stop more quickly than large vehicle
Side door beams provide protection
in collisions when lit at an angle
A vehicles speed when going downhill tends to
Energy of motion is another way of expressing
A vehicles driven into a curve tends to
go in a straight
Large vehicles, such as trucks and buses, have
slow stopping ability
How many collisions can occur when a vehicle hits a solid object?
All states that require that young children up to a certain age be protected by a
child safety seat
Child restraint seats musty be used
in the back seat
If a tire is underinflated, the only part that grips the road hard is
outside edges of the tire road
Good shock absorbers
help create traction
A vehicle going uphill works
against the force of gravity
One purpose of the tread pattern on tire is to
allow water to flow away from the tire
An air bag
automatically inflates to protect an occupant
In wet weather, with temperatures near the freezing point
a bridge roadway freezes before a bridge roadway
High energy of motion may cause a vehicle to
miss a tight curve
Modern seat belts
are three-point lap and shoulder safety belts
Factors that affect traction include
tires, shock absorbers, and steering systems
increases a speed increases
All-wheel drive means
power is supplies to four wheels
An important factor in maintaining traction is
good shock aborbers
A banked curve
is higher on the outside than on the inside
If your tires were out their center treads, they are
A restraint that provides protection without having to be handled by the occupant is called
a passive restraint
The 4-second rule is an estimate of
your stopping distance
Because of its energy of motion, when a vehicle's speed doubles, the vehicle needs about
four times the distance to stop
Three factors that determine force of impact are
speed, weight, and distance between impact and stopping
Restraint devices are designed to hold vehicle occupants in their seats during a collision
Your reaction distance is the distance it takes your vehicle to stop from the instant you see a hazard
Total stopping distance if the distance
your vehicle travels while you make a stop
The gripping action that keeps a tire from slipping on the roadway is called
The distance your vehicle travels while travels while you respond to a road hazard is called
What are the most important parts of control system?
The force that pulls objects toward the center of the earth is
The force that prevents slipping is called__________
What rule is used to estimate your total stopping distance under ideal conditions?
The time it takes you to act after perceiving a situation equals your reaction time
You drive through a curve at a speed higher than the posted speed. Your vehicle
needs more traction to stay on the roadways
The higher the speed of your vehicle, the more
it will tend to so straight
Which statement best describes reaction time?
It averages 3/4 of a second
The center of gravity of a vehicle is that point
around which all weight is evenly balanced
When a vehicles speed triples, how much more distance does it need to stop?
about nine times the distance
When you slow for a turn, some traction is used to slow, and some is
used to turn
Most states require use of child seats
Which energy-absorbing feature protects the driver in front-end collision?
the steering wheel and column
When braking and turning, you use
The second collision occurs when
the occupants hit the inside of the vehicle after a collison
The distance a vehicle travels fro the time the driver applies the brakes until the vehicle stops is
When moving object has something, what is the most important factor in determining how hard it hits?
The correct hand signal for a left turn is
left arm and hand extended straight out.
Making proper turns depends on
steering and speed control.
After completing a parallel parking maneuver, your vehicle should
be in the center of the parking space
Always prepare to straighten your vehicle after a turn by
using hand-over-hand steering.
A beginning driver may tend to oversteer. This means the driver
turns the steering wheel too much.
As you back your vehicle straight, your right arm should be over the back of the seat so you can
see through the rear window.
Just before beginning any lane-change maneuver,
check to see that the roadway ahead has no obstructions.
Prepare to make a turnabout safely by selecting
Prepare to make a turnabout safely by selecting
A right turn hand signal is indicated by
the left arm and hand pointing up.
Backing into a driveway or an alley on the right side
is the safest turnabout maneuver.
For a right turn, start turning the steering wheel when
the front wheels are even with the bend of the corner.
The hand signal to indicate slow or stop is
left arm and hand pointed downward.
Hand-over-hand steering involves
pulling the steering wheel down with one hand while your other hand crosses over to pull the wheel farther down.
A standard reference point might be
a hood ornament
How much space should be allotted to park your vehicle parallel to the curb?
