Module 8 Quiz
The amount of air pressure in your tires does not affect traction.
False
You do not need to slow down if you cannot keep a safe distance between your vehicle and another, as long as you think you can stop in time.
False
the force between two surfaces that resists the movement of one surface across the other
Friction
What reduces traction even more than rain?
Ice
This law states that objects at rest do not move unless some force acts on them
Inertia
When driving on a crowned road, you can gain more control of your vehicle by
Slowing down
A banked curve works with the force of gravity to help you stay on the road through the turn.
True
Centrifugal force pushes you in the direction opposite to the way you are turning.
True
The three major highway conditions that require you to adjust speed are changes in visibility, traction, and space.
True
To help estimate driving distances, you can use telephone poles as a general guide because they are evenly spaced about 100 feet apart.
True
roads built higher on the outside than on the inside
banked roads
roads built higher in the center than at either edge
crowned roads
Doubling your speed multiplies your braking distance by
four times
Natural laws include the law of
gravity
the distance traveled from the time your eyes see a hazard to the time your brain recognizes it
human-perception distance
Braking capability depends on
human-perception distance momentum vehicle-braking distance
What is the total stopping distance of a vehicle made up of?
human-reaction distance vehicle braking distance human-perception distance
the energy of motion
kinetic energy
You can raise a car's center of gravity by
loading a roof rack with items
a combination of an object's weight and speed
momentum
Smaller cars with lower centers of gravity are
more stable than cars with higher centers of gravity
What is it called when you are driving through a turn and the rear of the car slides around?
oversteering
When driving in the right lane on a two-way crowned road, gravity will tend to pull your vehicle to the
right
What can you do to lessen the force of impact in a head-on collision?
slow down steer to hit side
The closer you must drive to an object, your speed should be
slower/lower
Whether you need to speed up or slow down is determined by
the location of other vehicles in traffic
Human-reaction distance generally adds how much to total braking distance?
up to 66 feet
the distance the vehicle travels once the brakes have been applied
vehicle-braking distance
A car moving at 60 mph will take how much time to come to a complete stop?
4 to 6 seconds
After driving through heavy rain or deep puddles, you should always check for
Brakes
The minimum legal tread depth for the tires on your vehicle is
1/16 inch
At 55 mph, how much water does it take for tires to lose contact with the road?
1/2 inch
