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.

The best position for normal conditions.

When would you drive in position 2?

When would you ride in lane position 3?

Traffic Flow Minimize a Hazard - Moving away from a parked car or bike rider. Separate Hazards - More than one hazard, adjust your speed to deal with one hazard at a time. Compromise space - You cannot minimize or separate, decide to move away from the greater hazard toward the lesser hazard.

Minimize a Hazard

Separate The Hazards

Compromise Space Move away from the greater hazard (truck) toward a lesser hazard
