Signal Passed at Danger

A signal passed at danger (SPAD) in railway terminology of many countries, including Australia and the UK, occurs when a train passes a stop signal without authority to do so. The United States's National Transportation Safety Board (NTSB), which investigates railway accidents in that country, typically terms this as running a red signal.
