What should you do if you miss your exit on an interstate highway?

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

If you miss your exit on an interstate highway, the best course of action is to proceed to the next exit and turn around. This approach ensures safety by keeping you within the flow of traffic and preventing dangerous maneuvers such as backing up or making illegal U-turns. Interstate highways are designed for high-speed travel, and attempting to return to a missed exit can lead to accidents or create hazards for other drivers. Continuing to the next exit allows you to navigate safely and find a suitable place to turn around. This is essential because interstates have limited access points, and turning back at an uncontrolled area can be extremely risky. Always prioritize safety and adhere to traffic laws when driving.
