Discover the Driveway Assistance Device

Developed in partnership with state DOTs

Since 2011, Horizon Signal has worked alongside FHWA and numerous State DOTs to develop the DAD as an effective method for controlling residential driveway traffic. The DAD is engineered to manage traffic from driveways within a one-lane work zone. Flashing arrows direct drivers to make safe turns out of their driveway and into the construction zone.
