The 3 primary factors that determine the force of impact in a crash are:
speed, weight, and distance between impact and stopping
traction, brakes, and steering
tire tread, visibility, and four-wheel drive
wheel alignment, tire pressure, and roadway surface
The force that pulls objects towards the center of the earth is:
gravity
energy of motion
kinetic energy
inertia
Energy of motion is also called:
gas mileage
kinetic energy
the design of a vehicle's body
the effects of wind on vehicle control
Factors that affect traction include:
length and width of the roadway
oil, oil filter, and coolant levels
tires, shocks, and steering system
presence of other HTS users
If driving through a curve at a speed higher than the posted limit, the vehicle:
can add traction as needed to stay on the road
needs more traction to stay on the road
will adjust to the traction available
will always stay on the road
If the wheels lock when braking, you should
reduce traction
increase stopping distance
ease up on the pedal and squeeze down again
turn off the ignition
What does PSI stand for?
personal space inside
please start ignition
pounds served per inch
pounds per square inch
The law of inertia states that:
an object will accelerate towards the center of the earth
an object in motion will stay in motion until acted on by an outside force.
the force of friction is equal to or greater than the force of gravity
pounds per square inch = kilograms per kilometer
Kinetic energy is highest:
at the top of a hill
halfway down a hill
at the bottom of a hill
cheese is a good source of calcium
Check ALL of the vehicle parts that can help protect occupants in a crash:
airbags
seat belts
headrests
child safety seats
front & rear crumple zones
Braking distance will:
increase as speed increases
decreases as speed increases
doubles if speed doubles
increases as speed decreases
A vehicle going uphill works:
with the force of gravity
against the force of gravity
against the centrifugal force
with centrifugal force
The higher the speed of your vehicle, the more:
you will lose traction
it will tend to go straight
it will tend to drift sideways
you will feel the bumps in the pavement
High energy of motion may cause a vehicle to:
go around tight curves successfully
miss a tight curve
bank a curve
maintain good traction in a tight curve
If it is necessary to reduce speed to maintain control in a curve, when should you slow your vehicle?
Before entering the curve
After completing the curve
Prior to the apex of the curve
During the curve
Skids can be caused by:
reduced traction
driving too fast
changing directions too quickly
all of the above
A vehicle's speed when going downhill tends to:
decrease
stabilize
increase
cause instability
Going up a hill requires:
More acceleration
Cruise control
Slowing down
Use of the turn signals
What should you do first if you enter a curve too fast?
Avoid all potholes in the roadway
Brake gently as soon as you realize the curve is sharper than you thought
Accelerate moderately into the curve
Steer hard toward the curve
If the approach and beginning of a curve have been executed correctly, you can:
speed up gently coming out of the curve
hold the steering wheel at the right or left side
brake slightly in the middle of the curve
expect the vehicle to track without steering
Whenever you approach a yield sign at an intersection, you should:
always stop
give all oncoming cars the right of way
yield to vehicles on the left
yield to the first driver at the intersection
When preparing to make a lane change, what else should you do besides signal?
Make head and mirror checks
Slow down a little
Show a hand signal
Maintain a four-second following distance
Why could driving in a business district be more difficult than driving in other environments?
There are always more people present
More people ignore traffic laws in cities than in other locations
There are more hazards in city driving than in residential driving
There are fewer police officers in urban areas
When searching intersections, a good habit is to:
a. reduce speed before entering the intersection
b. search left and right before entering
c. move to lane position 3 for improved line-of-sight
A & B
An advantage of keeping a minimum of 3-4 seconds following distance in urban traffic is that you:
can see only the vehicle ahead of you
can see farther down the road
have less time to react to hazards
can predict and react to hazards more easily
While driving in congested urban conditions:
keep your vehicle close to others
cover the brake pedal
stay at the posted speed limit
signal a lane change 50 feet before the lane change
One-way streets are safest because the traffic flows in the same direction.
True
False
A good way to alert pedestrians or bicyclists to your presence is to blow the horn as you approach them.
True
False
Bus and bicycle lanes may be used by other drivers if no bus is present.
True
False
Which is NOT a characteristic of limited access highways?
high-speed traffic
divided by some barrier between opposing lanes of traffic
has a high rate of collisions
drivers can enter and exit only at certain points
3 types of interchanges at interstates are called:
flute, harp, & violin
diamond, trumpet, & cloverleaf
ruby, star, & heart
bear, owl, & eagle
Highway hypnosis is a driver condition that is affected by :
short trips on expressways
the driver staring at the roadway for long periods of time
frequent stops
entering and exiting too often
When choosing the ramp to enter the limited access highway, what should you do?
Use any ramp available to get on
Check for "Do Not Enter" or "Wrong Way" signs at the ramp.
Make sure the ramp is marked "Up"
Only make right turns to get on the entrance ramp
When merging onto the interstate, who has the right of way?
The vehicle entering if the speed up
The vehicles on the interstate
The vehicles on the entrance ramp
Play chicken!
You are driving and looking to get onto Interstate 90. What color will the sign be identifying I-90?
green & purple
black & white
yellow & black
red & blue
You are driving a long way on an interstate that has 3 lanes going in your direction, which lane should you drive in MOST of the time?
left
right
center
What is the safest following distance on the highway?
1 second
2 seconds
3 seconds
4+ seconds
Passing another vehicle is anytime. What makes it more dangerous on an expressway?
Speeds are higher and hazards can appear quickly
There are usually more open lines of sight ahead
Traffic travels at the same speed all the time
Traffic signs regulate where you can pass on the expressway
When passing another vehicle on the highway or interstate, when should you move back into the driving lane?
As soon as you get in front of the other vehicle
100 yards in front of the other vehicle
When you can see the front of the other vehicle in your side mirror
When you can see the front of the other vehicle in your rearview mirror
Which two forces act on a vehicle that has to use a runaway truck ramp?
gravity
inertia
friction
love
