What should a driver do if they miss their exit?

Answer: B — Proceed to the next exit and safely reverse course

If a driver misses their exit, the best course of action is to proceed to the next exit and safely reverse course. This approach is correct because trying to reverse back to the missed exit can create dangerous situations, including the risk of collisions and violating traffic laws. Stopping immediately can also be unsafe, as it may lead to confusion for other drivers and potentially result in an accident. Making a U-turn at the nearest opportunity is often not permissible, as U-turns are typically restricted in many areas and can lead to unsafe conditions. By taking the next exit, drivers can calmly and safely navigate back to their intended route, ensuring the safety of themselves and others on the road.
