D Junctions

As with T junctions and Y junctions and their corresponding letters, D junctions get their name due to looking like the letter D. D junctions aren’t widely used and it’s quite possible you’ll not have seen one due to being used in specific locations such as Maidstone, Kent.

They are effectively a T junction that divides, or splits at the end, though the minimal road markings can cause confusion to road users who are not familiar with them.

If you do have D junctions in your area, it’s likely that the examiner will use them as part of your driving test routes. Though the D junction resembles the Y junction, they should be used differently. This tutorial will explain how to correctly use D junctions.

  3. For merging onto the primary road, use the right fork for turning right.

Practice the Junctions

You may find that the local area is combined with other types of junctions and road markings may be faded due to poor maintenance. If you are learning to drive, use an experienced local driving instructor to take you through the various junctions within the area and practice them.
