You should call 9-1-1 anytime you are reporting an emergency situation. An emergency is defined as any situation where there is an immediate threat to life or property, and immediate action or assistance is needed. Some examples of when to call 9-1-1 include:
Crimes that are in progress
Injury traffic accidents
When Not to Call 9-1-1
Do not dial 9-1-1 unless you are reporting an emergency. Utilizing 9-1-1 for non-emergency situations may tie up the telephone lines for an actual emergency. Some examples of when not to call 9-1-1 are to report the following incidents:
Abandoned or illegally parked cars
For directory assistance or to ask for directions
Property crimes where there is no danger present and no chance of suspect apprehension (theft, vandalism, etc.)
If you are in doubt about whether or not your situation constitutes calling 9-1-1, go ahead and call.
What if I dial 9-1-1 by mistake?
Do not hang up! Please stay on the line and advise the dispatcher that you have dialed 9-1-1 by mistake and do not need emergency assistance. Whenever Communications receives a 9-1-1 hang-up or an incomplete 9-1-1 call, the caller must be recontacted to ensure that no emergency exists. If we are unable to confirm there is no emergency, or if the dispatcher detects anything unusual on a call back, police officers will be dispatched to check the location.
