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 and most appropriate action is to proceed to the next exit. This option emphasizes maintaining safety on the roadway. Stopping immediately can create a hazard for you and other drivers, as it could lead to a dangerous situation where you might be hit from behind. Attempting to back up to the missed exit is extremely unsafe and illegal, as it could cause accidents and disrupt traffic flow. Similarly, making a U-turn on a highway is prohibited in most areas due to the high speed of traffic and the risk of collision. Proceeding to the next exit allows you to safely navigate your route while minimizing disruption and maintaining the flow of traffic. This is the standard protocol for addressing missed exits on highways.
