Unit 3 2022 Part 1

How does gravity affect a vehicle going uphill?

• Gravity works with the vehicle
• Gravity works against the vehicle
• Gravity has no effect on the vehicle
• Gravity works with and against the Vehicle

Distance a vehicle travels from the time the driver applies the brakes until the vehicle stops?

• Perception Distance
• Braking Distance
• Total Stopping Distance
• Reactions Distance

What is the main purpose of the tread pattern on a tire?

• Reduces tire wear
• Reduces Traction
• Allows water to flow away from the tire
• Improve Traction

During a collision, What causes the driver to move forward?

• Friction
• Gravity
• Energy of Motion
• Inertia

When properly adjusted, a safety belt

• fits loosely across the body and tighten during a collision
• Fits snug across the hips and comfortably across the chest
• Fits snug across the upper body and hips
• Fits loosely across the hips and snug across the chest

As the driver travels into a curve, what will your vehicle tend to do?

• Go in a straight line
• Increase speed
• Increase Traction
• Become easier to control

Because of energy of motion, when a vehicle's speed doubles, the vehicle needs about

• Twice the distance to stop
• Half the distance to stop
• One-forth the distance to stop
• Four times the distance to stop

In wet weather, with temperatures near the freezing point

• Highway roadway will freeze before bridge roadway
• Bridge Roadway will freeze before highway roadway
• Bridge and Highway roadways will freeze at the same time
• Bridge and Highway roadways will not freeze

Three factors that determine force of impact are

• speed, weight, and distance between impact and stopping
• Traction, brakes and steering
• Tire tread, visibility, and four-wheel drive
• Shock absorbers, tire pressue, and roadway surface

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

• Passive restraint
• Semipassive restraint
• Active restraint
• Semiactive restraint
