These show who has the right of way at an intersection

Traffic signs and signals

One side of an intersection has a green light and arrow but the other side has a red light

An intersection with a left-turn light, a green arrow, or a delayed green light

Protected left turn

A traffic light that you have not seen change to green, or has been green for a long time

A stale green light

This helps water and snow flow away from traffic

Tread

He has three laws governing gravity and motion

Sir Isaac Newton

Besides the tires of your car, also helps increase traction

Shock absorbers

Another way of expressing kinetic energy

Energy of motion

The point all around where the weight of the vehicle is evenly balanced

Center of gravity

This part of a roadway freezes faster than others

A bridge

You should treat every uncontrolled intersection as if it had this sign:

A yield sign

You would expect to see sudden stops near these areas in a city

Near parked cars, intersections, and parking lots(Buisiness entrances)

Stop, yield, or traffic sign is present at this

A controlled intersection

This is created when stop or yield signs are present on two corners of an intersecting street

A through street

The time and distance traveled while you make a stop

Total stopping distance

The distance a vehicle travels from the time the driver applies the brakes to when the car comes on a total stop

Braking distance

The average reaction time of a human being when driving

3/4 of a second

When a vehicles speed doubles this change happens to its stopping distance

The stopping distance quadruples

The time and distance traveled while identifying, predicting, or deciding about a hazard

Perception time and distance

This active restraint device will improve your chances of survival in a collision

A seatbelt

A restraint that provides protection without the occupant having to handle it

A passive restraint

The most important part in the car’s control system

Tires

The part of your tires that wear down when your tires are underflated

Outside part of the tire

Slow down, steer right, honk your horn, and flash your lights

This type of roadways has the highest number of hazards per mile

City road/street

On a rural road, utility lines, mailboxes, and reflectors give clues to the locations of these

Driveways
