On a motorway, a red X appears above lane one before an exit slip, and the signs show the left lane is closed at the exit. What is the correct hazard-management principle?

1. Use lane one until the slip road because you intend to exit
2. Move safely to an open lane before the closure and do not drive in the red-X lane
3. Drive on the hard shoulder to reach the exit
4. Stop in lane one and wait for the X to clear
