We understand that someone can call 911 by accident. This often occurs when people have 911 preset on their telephone. It also happens quite often when people sit on their cell phone or bump it while it is in a purse or book bag. If you dial 911 by accident, please do not just hang up. Stay on the line and simply tell the dispatcher that you called by accident and that everything is okay. If you hang up instead, the dispatcher is required to call you back to determine whether or not you had an emergency. If no one answers when they call you back, law enforcement will automatically be sent to your location to investigate.
