You’re turning right onto a dual carriageway. What should you do if the central reservation is too narrow to contain your vehicle?

Explanation: When the central reservation is narrow, it may not be able to contain your vehicle. In this case, 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, your vehicle will stick out and cause an obstruction that may lead to a collision.
