12- Interstate Driving
Goal: Teach your teen interstate basics and how to safely enter and exit an interstate.
Location: Start on a multi-lane interstate with easily accessible exits, at a time when traffic is light, such as a weekend morning. Move on to practice at heavier traffic times when your teen is ready.
Lesson one – observation
Before your teen gets behind the wheel on the interstate, have your teen spend some time on interstates with you as the driver and your teen as the passenger. Emphasize the importance of looking ahead to anticipate potential problems, and explain key interstate features, such as:
- The different kinds of interchanges
- The meanings of interstate signs and signals
- The meanings of different lane lines and markings
Lesson two – on-ramp segments
Explain the three segments of on-ramps, and how they’re used:
- Entrance area: This stretch allows the driver time to search the interstate and evaluate how much space they have to enter and what speed is needed.
- Acceleration area: The driver brings the vehicle up to the speed of interstate traffic flow.
- Merge area: The driver uses this space to merge into the traffic flow.
Lesson three – merging
Teach the steps for merging onto an interstate:
- Check for on-ramp speed signs.
- At the entrance area, make quick glances at the interstate, scanning for vehicles and entry gaps.
- In the acceleration area, signal to show intent to enter the interstate and adjust speed to match the traffic flow.
- In the merge area, enter the flow of traffic, checking mirrors and blind spots.
- Turn off the turn signal and begin looking ahead to anticipate problems or upcoming lane changes.
- Do not completely stop in the entrance area unless absolutely necessary.
Lesson four – exiting
Teach the steps for exiting an interstate:
- Identify the exit well ahead of time.
- Scan traffic for problems when approaching the exit, but don’t slow down on the interstate.
- Start to signal four to six seconds before reaching the ramp.
- Upon entering the ramp, tap the brakes and begin rapidly reducing speed.
- Slow down to the posted exit ramp speed limit before reaching the curve.
Practice both merging and exiting 10-12 times each, or more if needed for your teen to feel comfortable.
Goal: Teach your teen to maneuver safely in complex interstate driving environments at higher speeds.
Location: Start on a multi-lane interstate with easily-accessible exits, at a time when traffic is light, such as a weekend morning. Move on to practice at heavier traffic times when your teen is ready.
Lesson one – steering technique
Once on the interstate, coach your teen on steering technique. At fast interstate speeds, excessive steering can be dangerous and lead to loss of control. Remind your teen to steer gently on interstates.
Lesson two – lane changing
In the high-speed, complex interstate environment, lane-changing skills are very important. Have your teen spend several miles practicing the lane-changing and passing skills previously learned in “Skill Nine: multi-lane roads,” until they are comfortable performing them at interstate speeds.
Remind your teen to:
- Watch for merging vehicles and move one lane left to make space for them when needed.
- Change lanes one at a time only.
- Watch mirrors for tailgaters and move to another lane to let them pass.
- Change lanes to move around any stopped vehicle with flashing lights.
Lesson three – three-second rule
Review the three-second rule for following distance, learned in “Skill Six: looking ahead.” Additionally, coach your teen to use a three-second rule for these interstate driving circumstances:
- Merging onto an interstate
- Changing lanes
- Exiting an interstate
Lesson four – challenging road conditions
Coach your teen to adjust travel speed and vehicle position based on weather and road conditions. Once your teen is comfortable with and proficient at interstate driving in good conditions, spend some practice time on interstates under more challenging conditions, such as rain. Coach them to always use appropriate caution, as conditions can change quickly.
Lesson five – road trips
Consider planning some short day trips with your teen to a destination two to three hours away. Have them drive there and back. Find an event or place that you will both enjoy and have fun.
