What should you do if you're about to miss your exit on the highway?

Answer: B — Proceed to the next exit and re-attempt

If you're about to miss your exit on the highway, the best course of action is to proceed to the next exit and then re-attempt to return to your desired route. This approach ensures your safety as well as the safety of others on the road. It allows you to maintain control of your vehicle and avoid risky maneuvers, such as sudden lane changes or stopping abruptly on the highway, which can lead to dangerous situations. By using the next exit, you can safely navigate through the traffic patterns and make the appropriate adjustments to your route without creating hazards for yourself or other drivers. After exiting, you can follow available local roads to return to the highway and continue your journey.
