Chapter 1 Vehicle Operation Flashcards
The distance from the center to the outside of a circle.
Radius
The transfer of a vehicle’s weight from side to side.
Roll
The ability to see clearly in darkness.
Night vision
Results when the loss of rolling friction causes loss of traction; the vehicle’s wheels still rotate but they do not control the vehicle’s movement.
Slide
A skid that occurs just before tires lose during braking; the tires lock and cause a skid.
Incipient skid
The loss of rolling friction that occurs when a vehicle’s wheels lock and do not turn while the vehicle is still rolling.
Skid
The force that pulls a vehicle toward the inside of a turn.
Centripetal force
Used to measure tire pressure.
Pounds per square inch
The ability to judge distance and space.
Depth perception
A turn that becomes wider during the turn much like a circle getting larger.
Increasing radius
A skid occurs just before the drive tires lose traction during acceleration.
Incipient spin
Ability to see above, below, and to the sides.
Peripheral vision
Pursuit termination technique in which an officer uses the patrol vehicle to make contact with the violator’s vehicle.
Pursuit immobilization technique
Pressing lightly on the brake pedal and then continuously applying increasing pressure to slow or stop the vehicle without losing traction.
Threshold braking
Looking in the desired direction of travel to avoid an obstacle and steering in that direction.
Eye targeting
Sharpness of vision
Acuity
The tendency for a vehicle traveling forward to straighten from a turn when the driver releases the steering wheel.
Caster effect
The phenomenon of the rear wheels following an inside path in relation to the front wheels during a turn.
Wheel tracking
Turning the vehicle’s front tires in the desired direction to regain traction.
Counter steering
The tendency of a vehicle to steer into a sharper turn than the driver intends.
Over steer
The ability to distinguish colors.
Color vision
A turn that remains the same throughout, getting neither wider nor smaller.
Constant radius
A computerized braking system that automatically slows and stops the vehicle when the driver applies a hard, steady pressure to the brake pedal.
Anti lock braking system
A turn that gets tighter during the turn much like a circle getting smaller.
Decreasing radius
The center point of any curve.
Apex
The tendency of a vehicle to turn less sharply than the driver intends.
Under steer
An active attempt by an officer in an authorized emergency vehicle to stop a vehicle that is being operated to elude apprehension or otherwise fails to stop after the driver realizes that the vehicle is being lawfully directed to stop.
Pursuit
Use of vehicles, barricades, cones, or other objects to partially or completely block traffic flow.
Roadblocks
Traction created when a vehicle’s tire constantly rotate against the road surface without losing traction.
Rolling friction
The transfer of a vehicle’s weight causing an end-for-end motion resulting in the vehicle turning 180 degrees.
Yaw
The reaction to centripetal force; force that pushes a vehicle toward the outside of a turn.
Centrifugal force
The transfer of a vehicle’s weight from front to rear or rear to front occurs during acceleration or braking.
Pitch
