If a driver is in a lane that ends, what must they do?

Answer: C — Yield to other vehicles

When a driver is in a lane that is designated to end, the correct action is to yield to other vehicles. This means the driver must be aware of their surroundings and give way to any traffic in the adjacent lane that may still be active. Yielding is crucial for maintaining safety and preventing collisions as the driver transitions out of a lane that is no longer available. While signaling before changing lanes is important for informing other drivers of your intentions, it does not capture the entire responsibility involved when a lane ends. Likewise, changing lanes immediately without caution can lead to unsafe conditions, and proceeding to the end of the lane at normal speed fails to consider the need to accommodate merging traffic and potentially could lead to conflicts with other vehicles. Yielding ensures a smoother transition and helps maintain safe driving conditions in situations where lanes merge or end.
