Summary

Description

A signal passed at danger (SPAD) occurs when a train passes a stop signal without authority to do so. SPADs are assigned a numerical ranking between 0 and 28 based on the severity of the incident. Those SPADs ranked at over 20 are those with the highest potential for serious consequences, while those between 16 and 19 are considered to have less serious potential. Those ranked from 1 to 15 carry little or no risk.
