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
