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

If you miss your exit on the highway, the appropriate course of action is to continue to the next exit and turn around. This option is correct because it prioritizes safety and adheres to traffic laws. Attempting to back up to your previous exit or making a U-turn on a highway is extremely dangerous and illegal, as highways are designed for continuous flow of traffic, and sudden stops or reversals can lead to accidents. Stopping to ask for directions can also be risky, as it can obstruct traffic and create confusion. Therefore, the correct approach is to proceed safely to the next exit, where you can turn around and get back on the right route.
