How are digital alerts different from lights and sirens?

Lights and sirens (L/S) rely on drivers having full visibility and unimpeded hearing to adequately alert drivers in time. Quieter car cabins, busier roads, and more driver distractions make L/S less effective today, and studies show that drivers have less than 3 seconds on average to safely react before collision.

Digital alerts use modern technology to extend the reach and efficacy of L/S by sending additional notification to drivers through the navigation systems they’re already using in real-time with as much as 30 seconds advance notice.
