What should you do if you miss your interchange?

Answer: B — Continue to the next interchange

Continuing to the next interchange is the correct action to take if you miss your interchange. This choice allows for safe navigation without putting yourself or others in danger. Backing up, making a U-turn, or using median crossovers can lead to risky situations. Backing up on highways is illegal and highly dangerous due to high-speed traffic; it's unpredictable and could result in a crash. Making a U-turn at an interchange may not be permitted, as many interchanges do not allow for turns due to safety concerns and traffic patterns. Using median crossovers is also risky, as they are designed for specific situations and not for general traffic correction, which could lead to dangerous maneuvers or illegal actions. By proceeding to the next interchange, you can safely turn around and return to your desired route without endangering yourself or other drivers.
