Total stopping distance is the distance

• it takes for you to perceive a hazard.
• it takes for you to brake.
• it takes for you to react to a hazard.
• your vehicle travels while you make a stop.

Large vehicles, such as trucks and buses, have

• good turning ability for quick turns.
• slow stopping ability.
• fast accelerating ability.
• quick braking ability.

If you drive through a curve at a speed higher than the posted speed, your vehicle

• can add traction as needed to stay on the roadway.
• needs more traction to stay on the roadway.
• will adjust to the traction available.
• will stay on the road.

If a tire is under inflated, the only part that grips the road well is the

• center of the tire tread.
• outside edges of the tire tread.
• tire cords.
• wear bar.

The force that keeps a tire from slipping on the roadway is called

• kinetic energy.
• friction.
• gravity.
• inertia

The distance a vehicle travels from the time the driver applies the brakes until the vehicle stops is

• perception distance.
• total stopping distance.
• reaction distance.
• braking distance.

Braking distance

• increases as speed decreases.
• decreases as speed increases.
• doubles if speed doubles.
• increases as speed increases.

All-wheel drive means

• power is supplied to four wheels.
• all four tires are inflated properly.
• your traction is reduced.
• power is in the front tires only.

When a moving object hits something, what is the most important factor in determining how hard it hits?

• gravity
• traction
• distance traveled
• speed

A restraint that provides protection without having to be handled by the occupant is called

• a passive restraint.
• a semipassive restraint.
• an active restraint.
• a semiactive restraint.
