What action must you take if you miss your exit on a highway?

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

If you miss your exit on a highway, the appropriate action is to proceed to the next exit and turn around. This practice ensures safety and compliance with traffic laws. Attempting to reverse back to the exit can create a hazardous situation, as it may lead to collisions with other vehicles and disrupt the flow of traffic. Stopping on the highway to ask for directions is also unsafe and can contribute to traffic congestion. Making a U-turn at the earliest opportunity may not be permissible or safe on a highway, as U-turns are often prohibited in certain areas. Therefore, going to the next exit allows you to safely and legally re-navigate back to your desired route.
