What should you do if you’re driving on a busy main road but notice you’re going in the wrong direction?

Explanation: If you discover you're going the wrong way, you should find a side road to turn around in. Don't attempt a U-turn or reverse from a side road onto the main road. Watch for pedestrians, cyclists, and other vehicles as you turn around, and ensure you're not obstructing any entrances or exits.
