2. Driving is a Thinking Task
Driving is a primarily a thinking task. Consider:
Aim high in steering to look far down the road
Keep your eyes moving to search for hazards
Get the big picture to be aware of your surroundings
Make sure others see you by using appropriate communication, lane position, and visibility

16. I.P.D.E. - Predict
actions of others
change of direction
points of conflict
consequences of your actions
Predict
Use knowledge, judgment, and experience to predict
When you predict, you take the information identified and imagine what might happen. Consider:
What is happening in your zones
What could happen
AND if it does happen…
How the change could affect you

Always consider the worst scenario

17. Predicting skills develop with driving experience.
How to Predict
To predict, you must evaluate the situation and make a judgment about the possible consequences.
Predicting skills develop with driving experience.

18. What to Predict
When predicting, there are three major elements in the traffic scene to consider:
Actions of other roadway users
Control over your own vehicle
Consequences of your actions
Image from:
See image similar to :
President:
Do not assume other roadway users will always take the correct action or see you.

19. Predicting Actions of Others
The most important types of predictions to make concerning the actions of others are:
Path – What might the other drivers do?
Action – What action will other users take?
Space – Will I have an open zone?
Point of conflict – If all zones are closed, where might a conflict occur?

Final Thoughts
Under inflated tires cause the engine to work harder. One sign of low tire pressure is if your tires squeal when cornering.
It’s like riding a bike with low tires. It’s hard to pedal because of the increased rolling resistance.
