Look where you want to go

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!!

• Sometimes you keep the same speed.

If you lock up the brakes you can

not steer!!

Lane positions

• Car is centered for normal driving. (Position 1)

• Car is 3 to 6 inches from the yellow line. (Position 2)

• Car is 3 to 6 inches from right line or curb. (Position 3)

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
