Question that could be on your test!
• What is the Smith System?
• An organized system to develop good seeing habits.
• What is Commentary driving?

• What is an orderly visual search pattern?
• A process of searching critical areas in a regular sequence.
The Smith System
• Aim High in steering!
• Get the Big Picture
• Keep Your Eyes Moving
• Leave Yourself an Out
• Make sure they see you
Before you start
The Driving Risk
• Driving can be the most dangerous thing you will do.
• What are some risks coming from the driver?
Risk Factors of Vehicle

• Poor brakes
• Dirty windows
• Worn wiper blades
• Broken headlights
Risk Factors of Roadway and Environment
• Bright sun
• Construction
• Dark shadows
• Rain
• Snow and ice
• Sharp curve
• Steep hill
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!! 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
