Here are a few best practices of when you should call 9-1-1. Remember to reserve 9-1-1 for an emergency that requires assistance from the police, fire department, or an ambulance. Do not call 9-1-1 if you want information about COVID-19, need a ride to the doctor's office, want to get tested, or have mild symptoms. Help us keep 9-1-1 lines open for emergencies!
