The dual carriageway you’re turning right onto has a very narrow central reservation. What should you do?

Explanation: When the central reservation is narrow, you should treat a dual carriageway as one road. Wait until the road is clear in both directions before emerging to turn right. If you try to treat it as two separate roads and wait in the middle, you're likely to cause an obstruction and possibly a collision.
