What it means

To show, lane by lane, whether the lane below the signal is open to you.

What you must do

• Steady red cross (S17) - indicates that you shall not drive in the lane over which the cross is displayed. That lane might be open to vehicles travelling in the opposite direction.
• Yellow arrow left (S18) and right (S19) - indicates that the lane you are driving in is closed ahead. You must leave the lane in the direction of the arrow.
