What should a driver do if they miss their exit on a highway?

When a driver misses their exit on a highway, the safest and most appropriate action is to continue to the next exit and find a way to turn around. This ensures that the driver remains on the roadway and avoids any dangerous maneuvers that could put themselves and others at risk.

Backing up to an exit is highly dangerous and illegal on highways, as it can lead to collisions or create confusion among other drivers. Making a U-turn is also not advisable since it's often prohibited on highways due to safety concerns. Stopping in the lane to wait for directions poses a significant risk, as it can lead to accidents due to the unexpected presence of a stationary vehicle in moving traffic. Therefore, continuing to the next exit is the best practice for maintaining safety on the road while navigating missed exits.
