According to a report from CBS4, the Denver (CO) Police Department (DPD) is examining the working ability of what’s called an Opticom system, which changes stoplights on the approach of an emergency vehicle. One person was killed and two others injured when a fire vehicle collided with a Honda Civic in the middle of a busy intersection on Saturday, January 23.
The Opticom can receive a signal from an approaching emergency vehicle and, on receipt, send out a signal to a receiver on a stoplight to turn it green. It can also turn the light red for crossing traffic.
On the date of the accident, a Denver Fire Rescue (DFR) truck was headed northwest on Speer to a call. DFR Captain Greg Pixley said the Honda was going south on Broadway. The lights were supposed to change about 1,000 to 3,000 feet before it reaches the intersection.
Britney Garcia, an eyewitness and driver at the intersection, said the stoplight appeared to change after that, saying it was green when she heard the fire trucks. However, when the fire truck arrived at the middle of the intersection, the light turned red.
The DFR One vehicle then “T-boned” the sedan, killing an adult female driver and critically injuring two passengers. Pixley said computer data and any video that turns up should determine if the Opticom system for changing the stoplights was working properly.
