Editing Signal passed at danger (section)

===Driver passes a signal at danger under their own authority===
If contact with the signaller cannot be made then the driver must not move the train, unless it is standing at one of the following signals:

* A signal controlled from a signal box that is closed on [[Absolute block signalling|absolute block]] line only. 
* An automatic signal where local instructions permit it, e.g. signals within tunnels on the [[Northern City Line#Operational procedures|Northern City Line]].

After passing a signal at danger under their own authority, the driver must stop at the next signal (even if it is showing a proceed aspect) and inform the signaller of what they have done.
