On September 15, 2015, Officer Ashley Kofahl was involved in a traffic collision while responding to a silent alarm. She was driving at 57 mph in a 30-mph zone without activating her siren. Upon learning the alarm was false, she deactivated her emergency lights but continued at high speed, resulting in a collision that caused severe injuries to another driver. The Michigan Court of Appeals denied her claim of governmental immunity, citing gross negligence due to her excessive speed and failure to use emergency signals.
