lesson 5.1THE IPDE PROCESS

Good searching habits and the ability to manage space on the roadway are basic tools for low-risk 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.

OBJECTIVE Name the four steps in the IPDE Process 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.identify2.predict3.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

OBJECTIVE Explain the three steps in the Zone 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
