Driver Education Chapter 4: The IPDE Process

Questions and Answers

What are three major factors that can contribute to the degree of risk you encounter while driving?

The driver, the vehicle, and the roadway and the environment.

What are the four steps in the IPDE Process?

Identify, Predict, Decide, and Execute.

What are the five steps of the Smith System?

Aim high in steering, Get the big picture, Keep your eyes moving, Leave yourself an out, Make yourself visible.

How is the Zone Control System structured?

Monitors six zones: left-front, front, right-front, left-rear, rear, and right-rear. Steps include seeing a zone change, checking other zones, and creating time and space. Signup and view all the answers

Study Notes

Risk Factors in Driving

Major factors influencing driving risk: driver, vehicle, roadway, and environment.

IPDE Process Steps

Four steps of the IPDE Process: Identify, Predict, Decide, and Execute.

Smith System

Five steps of the Smith System:
- Aim high in steering
- Get the big picture
- Keep your eyes moving
- Leave yourself an out
- Make yourself visible

Zone Control System

Comprises six monitoring zones: left-front, front, right-front, left-rear, rear, and right-rear.
Three-step approach:
- See a zone change
- Check other zones
- Create time and space through speed control, lane position, and communication.

Open vs Closed Zones

Open zone: area free of restrictions that is clear for sight and travel.
Closed zone: restricted space that should be avoided.

Role of Knowledge and Experience

Enhanced knowledge and experience lead to more accurate predictions in driving scenarios.

Decision Making in IPDE Process

Three key decisions to make: change speed, change direction, or communicate.

Lane Positions

Three available lane positions:
- Position 1: centered in the lane
- Position 2: close to the left side
- Position 3: close to the right side

Hazard Management

Minimize hazards by increasing space between yourself and the threat.
Separate multiple hazards by handling one at a time through speed adjustment.
Compromise space by allocating more distance to greater hazards.

Commentary Driving

Commentary driving involves verbalizing thoughts during the IPDE Process as a way of enhancing focus.

Time Consideration in IPDE Process

The IPDE Process is a continuous mental task requiring time for accurate identification, prediction, decision-making, and execution.
Complexity of traffic and the driver’s physical and emotional state can extend the time needed to complete the process effectively.
