6- Looking Ahead

Goal: Teach your teen to develop defensive driving techniques and higher-level visual and anticipatory driving skills before moving on to more complex driving situations. In order to avoid last-second reactions and spot potential hazards, have your teen always look 12–15 seconds down the road. When they are looking far enough ahead, they will be able to spot hazards early and be well prepared to react to them.

Location: Start on a quiet neighborhood street. Out of respect to our neighbors, please do not use official state road test courses for practice. Move onto a road with light traffic when your teen is ready.

Lesson one – IPDE system

Teach your teen the IPDE system, a simple system to help new drivers recognize, anticipate
and avoid risks before they turn into problems. IPDE stands for:

Identify potential risks, like oncoming vehicles, pedestrians, obstacles, or intersections.

Predict when and where there will be a conflict or problem.

Decide on the best course of action.

Execute that action.

Have your teen use commentary driving as they practice the IPDE system. As they drive, ask them to verbally describe their thoughts and actions in order to identify potential risks they see, predict problems these risks could cause, decide what to do to avoid a problem, and then execute the maneuver.

Lesson two – stopping-distance rule

Teach your teen the stopping-distance rule, for the safest distance to stop behind another vehicle. When your vehicle stops, you should be far enough away from the car in front of you that you can see where its tires make contact with the ground. Any closer is too close.

Lesson three – three-second rule

Teach your teen the three-second rule for the appropriate following distance when driving behind other vehicles. The three-second rule is an important safety measure designed to give drivers enough time to safely steer or brake to avoid problems that occur in front of them on the road.

  • Start counting when the rear bumper of the vehicle in front of you passes an object.
  • Count “one thousand ONE, one thousand TWO, one thousand THREE.”
  • Your front bumper should not pass that same object before you’ve reached “three.”

Have your teen practice the three-second rule at least 10–12 times, counting out loud to check whether their following distance is appropriate.

Your front bumper should not pass before you’ve reached “three.”

Idaho’s Basic Rule for speed

Idaho law requires you drive at a speed that is “reasonable and prudent” at all times. The posted speed limit of 55 mph may not be safe when the roadway is icy.


Don’t tailgate

Rear-end collisions are the most common form of a car crash. Emphasize to your teen that increasing following distance behind other vehicles is the single best thing they can do to minimize the risk of a crash.
