A steady red 'X' at lane use control lights means you should not enter or use that lane.
Step-by-step explanation:
A steady red 'X' at lane use control lights means you should not enter or use that lane. Lane use control lights are often used to help manage and control traffic flow on highways and expressways. They are typically used to indicate when certain lanes are closed or not available for use, such as during road construction or emergencies.
Ignoring a steady red 'X' can be dangerous and is often illegal. It is important to follow the instructions provided by lane use control lights to ensure the safety of yourself and others on the road.
