The IPDE Process will help you lower the Risk of Driving • Good seeing habits and your ability to manage space are the basic tools for low risk driving. • The IPDE Process is an organized system of seeing, thinking and responding. • The four steps of the IPDE Process are: Identify Predict Decide and Execute

Identify • • • What are you trying to identify? Open and closed zones Specific clues Other roadway users Roadway features and conditions Traffic controls

What can you Identify? I have cars & trucks all around me. I must keep a space cushion and identify hazards!

Predict • Use knowledge, judgment and experience to predict: • The actions of others • Speed • Direction • Control • Points of conflict

What do you Identify and Predict? Four way stop, stop line, School zone-20 MPH, other vehicles. School Bus, Crossing guard

What do you Identify and Predict?

Decide • Once you have Identified a situation and Predict a possible conflict, you then Decide upon an action. • Deciding is a very important mental task. • You must continually Identify and Predict until you have enough information to make correct decisions.

Execute • Carrying out your decision to avoid a conflict is the Execute step in the IPDE process. • This is the physical step of IPDE. • The important actions you can execute are: control speed, steer, and communicate. • Other actions include: using the heater, defroster, and wipers.

Control Speed • You may speed up to avoid a hazard. • You may slow down or stop to avoid a hazard. Check your rear zone when braking. • Don’t lock up your brakes!! Can not steer! • Sometimes you keep the same speed.
