EVOC Pt. 2 Flashcards
Hydroplane
A gradual loss of traction due to a fluid build up between the tires and the road surface.
Identify
recognizing hazards while driving.
Inertia
With no force exerted on it, a body at rest will remain at rest, while a body in motion will remain in motion in a straight line at a constant speed.
Kinetic Energy
The energy of motion as it relates to sped.
Median Plan of Sound
When sound is received by both ears at the same time with the same intensity- unable to locate origin.
Peripheral Vision
Gives us information on objects moving into our focal vision- help perceive sensations such as speed.
Phototropism
(Moth Effect) The tendency of the eyes, especially when fatigued or drug influenced- to be attracted to light
Predict
anticipation what a potential hazard will do
Reaction Distance
3/4 of a second- the distance traveled from the time a hazard is noted until pressure is applied to the brake pedal.
Rods
The part of the eye responsible for night vision.
Sensing
using the senses to help locate hazards.
Shuffle Steering
A steering technique in which both hands remain in contact with the wheel and driver.
S.I.P.D.E.
A five step approach to crash avoidance.
Siren
An audible warning device.
Smith System
A type of defensive driving.
Space Cushion
An area around your vehicle (360 degrees) maintained to allow response to a hazard.
Static
Motionless
Stopping Distance
The distance necessary to affect a complete stop from a given speed.
Traction
Interaction between tires and road surface which allows your vehicle to start, stop, and turn.
Velocity
Distance traveled in a specified amount of time.
Visual Lead Time
The time and distance ahead of your vehicle to be aware of to identify hazards.
Zone of Confusion
A 10 degree angle from each ear–extending in a cone shape- unable to determine direction
