Why do the trucks driving down the road with lights/sirens sometimes just shut their lights and siren off?

Sometimes when we are responding to a call we are “canceled enroute”. This means the situation to which we were responding has been mitigated and we are no longer needed. Usually one of the responding vehicles will continue to the scene of the incident at normal speed to make a report.

In the case of our trucks responding to a mutual aid run in another municipality we will simply end our response and return to our station.
