If you miss your exit on the highway, what should you do?

Answer: C — Proceed to the next exit and turn around safely

Proceeding to the next exit and turning around safely is the proper course of action if you miss your exit on the highway. This approach prioritizes safety and adheres to traffic laws. Attempting to backtrack by reversing or making a U-turn can be incredibly dangerous due to high-speed traffic and the risk of collisions. Stopping on the highway or waiting for guidance is impractical and can lead to serious accidents. Therefore, taking the next exit allows you to safely and legally find your way back without endangering yourself or other drivers. This demonstrates an understanding of proper highway navigation and the importance of ensuring safety while driving.
