You should call 911 anytime you have an emergency situation, like a fire, a serious injury or medical condition, a crime in progress or anytime you need to speak with a police officer. When you call 911 an emergency dispatcher will answer the phone and ask you for details about your situation. Please speak clearly and calmly to the dispatcher. If you dial 911 by accident, please stay on the line and advise the dispatcher that the call to 911 was an accident. If you dial 911 and hang up without speaking to a dispatcher, a police officer will most likely be sent to the location the call was made from.
