2. 3 Major Risk Factors Risk factors can be contributed by: The driver
2. The roadway & environment
3. The vehicle
Examples: adjusting radio, being angry, using cell phone, texting
Examples: bright sun, construction, snow & ice, curve
Examples: bald tires, dirty windshield, poor brakes

3. IPDE
Identify
Predict

4. Lets talk about the IPDE process

5. EXAMPLE

6. Smith System- gives you rules to help you learn how to look at traffic situations
Aim high in steering
Get the big picture
Keep your eyes moving
Leave yourself an “out”
Make sure others see you.

7. Zone Control System
Open books to page 65

8. How are you going to look, search or IDENTIFY?
# 1 Orderly visual search pattern- a process of searching critical areas in a regular sequence

9. look, search or IDENTIFY?
How are you going to
look, search or IDENTIFY?
# 2 Clues –look for:
1. other users - ex: movement of others, pedestrians or bicyclists, develop habit of ground viewing
2. roadway features and conditions – ex: multilane to single lane, roadway surface, road hazards
3. traffic controls– ex: signs, traffic signals, police officers

10. Predict IPDE Actions of others
Control of your vehicle and possible consequences

11. Decide IPDE It is a mental task Very important
Examples: maintain speed, change direction, communicate to others, or a combination of these
Note lane positions on page 76

12. Execute IPDE Carrying out a decision to avoid conflict
Actions to execute include: controlling speed, steering, and communication

13. To help maintain safe path use the following techniques
Minimize a hazard
Put more distance between yourself & the hazard
Separate Hazards
Adjust speed to deal with one hazard at a time
Compromise Space
Give as much space as possible to the greater hazard

14. Many crashes can be avoided if a driver simply ????
Communicates!!!!

15. How can you communicate while driving…
Headlights
Taillights
Brake lights
Turn signals
Hazard flashers
Back-up lights
Horn
Vehicle position
Eye contact & body movement
Combination of actions
