What should you do when you see this sign as you travel along a motorway?

Explanation: You'll see this sign if the motorway is closed ahead. Pull into the left-hand lane as soon as it's safe to do so. Don't wait until the last moment before you move across, because the lane may be busy and you'll have to rely on another driver making room for you.
