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

Answer: C — Proceed to the next exit, then return

If you miss your exit on the highway, the best course of action is to proceed to the next exit and then return. This approach is safe and complies with traffic laws. Stopping on the highway or attempting to reverse can create significant hazards, both for yourself and other drivers, as it can lead to collisions or obstruct traffic flow. Turning around in the median is not permitted and poses serious risks, as it's illegal and could lead to overwhelming danger. By taking the next exit, you allow yourself the chance to safely navigate back to your intended route without endangering yourself or others on the road. This strategy promotes safe driving practices and ensures that you are not making sudden or illegal maneuvers that could lead to accidents.
