SaferStreet’s SmartSigns uses a combination of microwave and infrared sensors to detect if a driver is distracted using their smartphone, speeding, not wearing a seatbelt, or just not paying attention. They are currently being tested in King County, which includes Seattle, Fairwood, Pacific, Algona, Maple Valley, White Center, Skyway, Kenmore, Issaquah, and Newcastle.
How does it work? The signs look for a certain heat signature to detect if there is a mobile device in someone’s hand. If a SmartSign does detect a smartphone, the sensor relays a message to a sign in front of the driver that reads: ‘Phone Down.’ They are not currently being used to issue citations, but rather to alert drivers of their speed and possibly distracted driving.

Each time a driver passes a SmartSign, it reminds them to drive safely, and that can make a real difference in their behavior. For instance, SmartSigns reduce distracted driving by up to 40% when left in one area over a four week period. By rotating these signs throughout King County, we can help create a safer driving environment throughout the surrounding community,” said Tim Hogan, SaferStreet Solutions CEO.
