When approaching the sign that indicates "right lane ends ahead," what should drivers do?

When approaching a sign that indicates "right lane ends ahead," the appropriate action for drivers is to merge left if possible. This sign alerts drivers that the right lane will no longer be available further along the road, which means they need to safely transition to the left lane to continue their travel without interruption.

Merging left allows drivers to maintain a smooth flow of traffic while adhering to the rules of the road. It is important for drivers to signal their intentions to change lanes and to ensure that they do so safely, checking for other vehicles in the lane they are merging into. This kind of proactive behavior helps prevent potential collisions and congestion.

While maintaining speed in the right lane would likely lead to confusion and potentially unsafe situations as drivers attempt to navigate the ending lane, failing to signal when changing lanes can create hazards. Finally, preparing to stop is unnecessary unless traffic conditions dictate such an action; in most cases, merging left is the more appropriate response to ensure safety and traffic efficiency.
