Help residents go with the flow.
Discover the Driveway Assistance DeviceDeveloped 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.
At a glance
The DAD can be built on our compact SQ2 cart and our powerful SQ2T trailer signal platforms.
