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

Answer: C — Continue to the next exit

If you miss your exit on a highway, the safest and most appropriate action is to continue to the next exit. This practice helps maintain the smooth flow of traffic and ensures your safety and the safety of others on the road. When you continue to the next exit, you will find a safe opportunity to turn around or change your route without risking accidents or causing disruptions. Backing up on a highway is extremely dangerous and illegal, as it puts you and other motorists at significant risk. Making a U-turn is also not advisable because many highways do not allow U-turns for safety reasons, and attempting one can lead to serious accidents. Stopping to ask for directions on a busy highway is impractical and can create hazardous situations, as stopping suddenly can result in collisions or other dangerous scenarios. Therefore, opting to continue to the next exit is the best and safest choice when you miss your exit.
