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

Answer: B — Proceed to the next exit and turn around

If you miss your exit on the highway, the best course of action is to proceed to the next exit and turn around. This method is both safe and compliant with traffic laws. It allows you to reorient yourself without endangering yourself or other motorists. Backing up to the exit poses significant risks, as it can lead to accidents or complicate traffic flow. Making a U-turn is generally not permitted on highways and can also create dangerous situations. Stopping on a highway can lead to collisions, as vehicles may not expect a stationary car in a lane of traffic. Therefore, the safest and most responsible approach is to continue to the next exit, where you can safely turn around and get back on track.
