Open and Closed junctions

When approaching a junction to emerge, you should decide if the junction is open or closed. An open junction is one where you are able to clearly see whether it is safe to emerge or whether you will have to give way to oncoming traffic. An open junction would look like the diagram below.

A closed junction would mean that you are unable to see clearly if there are any other road users approaching from either direction. This would mean that you are unable to decide if it will be safe to cross the give way line or not and will have to approach the junction at a slower speed. An example of a closed junction is shown below, the right hand side is closed by the trees and the left hand side is closed by the house.
