properly inflated.
overinflated.
flat.
under inflated.
Three factors that affect braking distance are
car and roadway conditions and speed.
tread depth, controlled recovery, and the motion of energy.
steering ability, centrifugal force, and ocular tracing.
engine power, tire pressure, and wind resistance.
If you are trying to get out of a skid, you should
look for wet leaves to slow you down.
accelerate quickly.
slam on the brakes.
keep your foot off the pedals and steer in the direction that you want the vehicle to go.
If your vehicle has good directional control,
you can drive without using brakes.
you can make sharp turns at high speed.
you will be able to keep the vehicle moving in the direction in which you steer it.
you can decrease total stopping distance by 3 seconds.
After driving through a deep puddle, you should
stop at the nearest service station for brake fluid.
apply light pressure to the brake pedal.
only use engine braking for a while.
turn off the engine.
A power skid occurs when you
apply the brakes too hard.
press the accelerator too hard.
downshift too quickly.
turn the steering wheel sharply.
A driver can turn successfully as long as there is enough
adhesion to overcome friction.

speed to maintain balance.
friction to overcome centrifugal force.
Because of inertia,
