Stockholm ambulances to trial blocking drivers’ music so sirens can be heard. The Telegraph reports that a new alert system is being trialed in Stockholm, Sweden that “overrides loud music and bypasses sound-proofed car insulation so drivers will never be caught off guard by an approaching emergency vehicle.” The new system “uses the FM radio signal to jam drivers’ speakers and send a voice alert that an ambulance is approaching.” The reason for the new system was the realization that drivers often had only seconds to react to a siren when the a better warning time is at least 10 to 15 seconds. The alert will only work on cars that have the radio on, but it’s estimated that it will reach two-thirds of the cars on the road.
If this system works, one would hope that emergency vehicle sirens could be adjusted so that pedestrians and other people nearby could be spared ear-splitting siren volumes in the attempt to alert distracted motorists. It doesn’t hurt to dream.
