@smac7915: Know When to Call 9-1-1 9-1-1 is for emergencies that require immediate assistance: such as a serious medical emergency, fire, crash with injuries, or a crime in progress. If it’s an emergency, call 9-1-1. If it’s not an emergency, please use one of the appropriate non-emergency numbers. This helps keep 9-1-1 lines available for people who need immediate help. When in doubt about a true emergency, it’s always okay to call 9-1-1.
