There are also a number of Y-junctions. The one shown below requires that when emerging and turning right, you need to turn right into the short two-way section, then right again onto the main road (red line)
This very large Y-junction is by the town at the seafront. It's unusual in that it is one-way either side. If you turn in from the seafront, from the direction in the photo (below), you may have to give way.
