How is using the IPDE System on interstate highways different from using it on other roadways?
Identify: since you are traveling at higher speeds and traveling in multiple lanes you have to get visual information farther ahead, identify closed front zones early. Predict: You must search ahead to your target area to watch for slower traffic or for drivers changing lanes. Decide: Driving speeds for highways demand that you make decisions quicker. Last-second decisions and driving adjustments can quickly change your safe path of travel, and may close more than one zone. Execute: Execute your decisions smoothly and signal early for maneuvers and maintain a 3 second following distance.
