What does a red X lane use signal mean?

A red X lane use signal indicates that drivers are not permitted to use that lane. This signal is a clear indication that the lane is closed to traffic, often due to construction, an accident ahead, or other safety concerns. It helps manage the flow of traffic and ensures the safety of both the drivers and any workers or emergency responders who may be in the area.

While proceeding with caution, merging to another lane, or encountering a speed limit increase might apply to various driving situations, they are not relevant to the meaning of a red X. The key aspect of the red X signal is its definitive prohibition against using that lane. Understanding this traffic signal is crucial for safe driving and compliance with roadway regulations.
