Overdriving your headlights means

45

When driving at night with low beam headlights, the maximum safe speed is

low beam lights

In fog, you should use

when the rain first begins

A wet roadway is most slippery

hydroplanning

- is caused by a buildup of water between the tires and road surface

- results in loss of steering

- results in loss of braking

Dirty headlights can reduce visibility up to 90%.

false

The use of cruise control can help control a vehicle in snow.

true

Bridges freeze before road surfaces.

true

The use of the air conditioner will help defog interior windows.

1/2

Nearly ____ of all flash flood fatalities are vehicle related.

a film of water builds up between the road surface and the vehicles tires

Hydroplanning occurs when

- the roadbed may be washed away

- your vehicle may stall

A danger of driving through deep water is

brake gently using your left foot while accelerating with your right foot

To dry wet brakes, you should

50/50

The recommended antifreeze/water mixture is

- can reduce visibility to ½ mile or less

- strike with little warning

- often damage oil and air filters

Dust or sand storms

these surfaces freeze before other road surfaces

Bridges and overpasses can be even more hazardous during cold weather because

look and steer in the direction you want to go

If you begin to slide on a slick surface,

high winds

Buffeting results from

accelerate

When driving into a headwind, you may need to

true

Two feet of water will carry away most vehicles.

False

Removing the radiator cap is advisable as it will help release steam and cool an overheated engine quicker.

true

Kitty litter can help the tires gain traction on slick surfaces.

true

As more streets and parking lots are built, flooding problems will increase.

false

When driving through water, stay close to the shoulder

true

A driver can lose control of a vehicle in 6 inches of water.

true

Tire pressure increases as the tires get hot.

true

Before starting a vehicle in snow, check to be sure the exhaust system is clear.

alert inattentive drivers

Rumble strips

make impact with signs less forceful

Breakaway posts

are prefabricated islands

Median barriers

reduce hazard of guardrail ends

Extruder terminals

liquid or sand filled drum

Crash attenuators

used to warn drivers of dangers ahead

Message signs

allows driver to steer while braking

ABS

activates brake sensors, which don't allow the wheels to spin. The process is basically the reverse of anti-lock brakes. the device allows acceleration input to the tires without loss of vehicle balance.

Traction Control

adjusts vehicle balance

Suspension Control

activates when vehicle is not going in the direction it is being steered

ESP

motion based sensory input

A driver's first indication of traction loss comes from

- surface materials

- surface conditions

- weather conditions

Which of the following will affect traction?

to the rear

Sudden acceleration causes vehicle weight transfer

weight transfer to the left

Suddenly steering to the right will result in

loss of front traction

Understeer results from

- look where he/she wants the vehicle to go

- steer in the intended path of travel

In skid control, it is critical that the driver

-

In rear wheel loss of traction,

true

A good technique to minimize understeer is to slow down before entering a curve or turn.

true

In vehicles without ABS, a quick jab of the brakes may help control front wheel traction loss.

true

Slight acceleration is helpful in an oversteer situation.

false

Understeering results from too little steering by the driver.

false

Oversteering results in a front wheel skid.

When driving an airbag equipped vehicle,

true

The safest place for children is in the back seat.

true

If an infant must ride in the front seat, the air bag should be turned off.

false

If your vehicle has air bags, you do not need to use safety belts.
