Q: You're turning right at a large roundabout. What should you do before you cross a lane to reach your exit?
Explanation
On busy roundabouts, traffic may be moving very quickly and changing lanes suddenly. You need to be aware of what's happening all around you. Before crossing lanes to the left, make sure you take a lifesaver glance to the left. This gives you time to react if it isn't safe to make the manoeuvre.
