The city’s fire department is testing out a new device that could help drivers using navigational apps steer clear of firetrucks responding to an emergency, helping improve safety for both drivers and firefighters, the Patriot Ledger reported. The device, a small black box about four inches tall and wide, sends out alerts to drivers about the locations of the trucks to drivers using a navigation app called Waze. The company that makes the device, Chicago-based Haas Alerts, hopes the alerts will eventually be incorporated into other navigational apps as well as heads-up driving displays in cars. “People would be heading toward the emergency, unknowingly,” Quincy Fire Deputy Chief Joe Jackson said. “This allows people to avoid it.”
