Motorway signs
Light signal conveying the prohibition that vehicular traffic may not use the lane below the sign (gantry-mounted)
What it means
A red X on the gantry closes the lane directly underneath it, usually for a breakdown, a crash or work you cannot see yet. Move into an open lane in good time, well before you reach the gantry. You MUST NOT drive in a lane showing a red X.
