Tidal flow lane control
Lane control signal indicating that vehicles may not proceed along the lane directly beneath the signal
What it means
A red cross above your lane means that lane is closed to you, often because it has been handed to traffic coming the other way. Move out of it into a lane showing a green arrow before you reach the signal. You MUST NOT drive on past a red cross in that lane, and the closure only lifts when the signal changes - a white diagonal arrow is telling you to move over, not that the lane ahead is clear.
