Safe railways for Australia

Signals passed at danger


A signal passed at danger (SPAD) is an occurrence where a train passes a signal displaying a stop indication without the authority to do so.

Only a small percentage of SPADs result in a serious accident but they provide warnings about failures or deficiencies in safety risk controls, including those associated with human factors.

Certain SPAD and Light Rail or Tram Authority Exceeded (LRTAEs) occurrences are required to be reported immediately as a prescribed incident. For more information see the Notifiable Occurrence webpage.
