What does a red "X" mean in a lane?

A red "X" displayed in a lane signals that the lane is closed to traffic. This indicator serves as a clear visual cue for drivers to abandon the lane for safety reasons. It is commonly used in situations such as road work, lane reconfigurations, or accidents that may obstruct the lane.

Drivers approaching a lane with a red "X" should not enter or use that lane, helping to ensure both their safety and the safety of any work crews or personnel that might be present. Understanding this signaling is crucial for proper lane discipline and adherence to traffic rules, helping to prevent accidents and maintain efficient traffic flow.
