lesson 5.1
THE IPDE PROCESS
Good searching habits and the
ability to manage space on the
roadway are basic tools for lowrisk driving.
The IPDE Process along with the
Zone Control System can help
you enjoy low-risk and low-stress
driving.

OBJECTIVE
Describe three factors that contribute to the
degree of risk you face when driving.
Understanding Risk Factors
Risk factors are anything that increases the possibility of
a collision.
As you drive, be aware that all of the risk factors—either
separately or together—play a major role in the level of risk
you face.
What risk factors do you
identify in this traffic scene?
Driver-Contributed Factors
When driving, you create risk when you
•
•
•
•
adjust the radio
comb your hair
use a cell phone
eat or drink
Other drivers who take unnecessary chances can increase
your level of risk and chance of conflict.
Vehicle-Contributed Factors
As a driver, it is your responsibility to properly maintain
your vehicle.
Conditions that can contribute to the possibility of a crash
include vehicles with:
•
•
•
•
bald tires
dirty windshields
broken headlights
worn wiper blades
Roadway- and Environment-Contributed
Factors
• Conditions such as bright sun, dark shadows, and glare
contribute to driving risk.
• Road construction, a sharp curve in the road, or ice and
snow also create risk
for drivers.
Name the four steps in the IPDE Process
OBJECTIVE and explain how IPDE helps you to be a
low-risk driver.
The IPDE Process
Driving is primarily a thinking task. Drivers who develop an
organized system that deals with all traffic possibilities have
fewer crashes than drivers who don’t use an organized
system.
The IPDE Process is an organized system of:
• seeing
• thinking
• responding
IPDE represents the four steps for safe driving:
1. identify
2. predict
3. decide
4. execute
You begin the IPDE Process by “reading” traffic
situations to gather information in order to make
your decision and execute them.
To process information properly, you must
•
•
•
•
identify hazards
predict points of conflict
decide how to avoid the conflict
execute the correct action
Explain the three steps in the Zone
OBJECTIVE Control System and how they contribute to
low-risk driving.
The Zone Control System is an organized method for
managing six zones of space surrounding your vehicle.
Zone Control allows you to see and respond to changes in
the traffic environment at a time when best control can be
achieved.
Using the IPDE Process in conjunction with the Zone
Control System will help you develop behaviors that will
make you a safe and responsible driver.
The Zone Control System includes the following steps:
1. See a zone change.
2. Check other zones.
3. Create time and space by getting the best:
• speed control
• lane position
• communication
