IPDE Process

A four-step defensive driving routine - identify, predict, decide, execute - in which the driver searches for hazards, forecasts what could happen, chooses a response, and carries it out smoothly.

Related: Visual Scanning, Space Cushion
Space Cushion

The clear area of roadway kept around a vehicle on all sides so the driver has room and time to react; it is created and maintained by adjusting speed and lane position.

Related: Three-Second Rule, Lane Position, IPDE Process
Three-Second Rule

A way to set following distance in good conditions: the driver notes when the vehicle ahead passes a fixed object, then counts at least three seconds before reaching that same object.

Related: Space Cushion, Visual Scanning
Blind Spot

The area alongside and slightly behind a vehicle that mirrors do not show; a driver must turn the head to check it before changing lanes or merging.

Related: Lane Position, Visual Scanning
Hydroplaning

Loss of tire contact with the pavement caused by water building up under the tires, which removes steering and braking control until the vehicle slows and the tires grip again.

Related: Skid, Space Cushion
Visual Scanning

The habit of looking well ahead, to both sides, and in the mirrors on a continuous cycle instead of staring at the vehicle in front, so hazards are spotted early.

Related: IPDE Process, Blind Spot
Distracted Driving

Any activity that draws a driver's eyes, hands, or attention away from the driving task, such as texting, adjusting controls, eating, or interacting with passengers.

Related: Visual Scanning, IPDE Process
Threshold Braking

Braking just short of the point where the wheels lock, producing maximum stopping force while keeping enough steering control to steer around a hazard.

Related: Anti-lock Braking System (ABS), Skid
Anti-lock Braking System (ABS)

An electronic system that rapidly releases and reapplies brake pressure to keep wheels from locking during hard stops, so the driver can brake firmly and steer at the same time.

Related: Threshold Braking, Skid
Skid

A loss of tire grip in which the vehicle slides instead of following the steering input; recovery calls for looking and steering where the driver wants to go while easing off the accelerator.

Related: Understeer, Oversteer, Hydroplaning
Understeer

A condition in which the front tires lose grip first, so the vehicle keeps traveling straight despite steering input; the driver should ease off the accelerator and reduce the steering angle.

Related: Oversteer, Skid
Oversteer

A condition in which the rear tires lose grip first and the back of the vehicle swings outward; the driver should look and steer toward the intended path while easing off the accelerator.

Related: Understeer, Skid
Lane Position

Where the vehicle sits within its lane - left, center, or right - chosen by the driver to gain space from hazards and to set up turns or lane changes.

Related: Space Cushion, Reference Point
Reference Point

A fixed visual cue, such as the edge of the hood or a side mirror, that a driver uses to judge the vehicle's position for parking, lane placement, and turning.

Related: Lane Position, Hill Parking
Hill Parking
