What should you do if you miss your exit on the highway?

Answer: C — Proceed to the next exit

If you miss your exit on the highway, the safest action to take is to proceed to the next exit. This approach ensures that you do not create a dangerous situation for yourself or other drivers. Reversing back to the missed exit or making an immediate U-turn on a highway is highly unsafe and illegal; such maneuvers can lead to collisions and disrupt the flow of traffic. Stopping on the highway to assess the situation is also unsafe, as it can cause accidents due to sudden stops in a high-speed environment. By continuing to the next exit, you can find a safe place to turn around and navigate back to your intended route without endangering yourself or others.
