If there are red flashing lights above a single lane on the motorway, what should you do?

  1. Ignore if not in that lane

  2. Move into another lane as soon as it is safe to do so

  3. Stop immediately

  4. Accelerate through the lane

The correct answer is: Move into another lane as soon as it is safe to do so

If there are red flashing lights above a single lane on the motorway, it means there is a lane closure or obstruction ahead. Ignoring it and continuing through the lane is dangerous and can lead to a collision. Stopping immediately is also not recommended as it can cause a traffic build-up and may not be necessary unless instructed by a traffic officer. Accelerating through the lane is also not advised as it could potentially lead to an accident. Therefore, your best option is to move into another lane as soon as it is safe to do so, in order to avoid the obstruction ahead.
