SALT LAKE CITY -- Ambulances racing along major routes to University of Utah hospitals are no longer subject to red lights.
The Utah Department of Transportation announced this week that ambulance drivers can now trigger traffic lights to cycle to green.
The Salt Lake Tribune reports that ambulance devices now control about three dozen intersections in the city.
Doctors say the devices could save lives, allowing ambulances to reach hospitals faster. They say a few extra minutes can determine whether a patient lives or dies.
UDOT engineer Peter Jager says the green-light remote controls will make the roads safer for ambulances and other drivers.
Other intersections in the Salt Lake Valley already have the devices. This new set streamlines routes to hospitals from interstates 15 and 80.
