Specialized Signs and Signals

Construction/Maintenance Signs & Signals:

Traffic control devices are used in road construction and maintenance work areas to direct drivers and other road users safely through the work site. Be prepared to reduce your speed and use caution when directed to do so by a sign, flagger, or law enforcement officer. Failure to do so is illegal and is dangerous to those working in the construction zone.

Construction and Maintenance Signs:

The signs—usually diamond shaped and/or orange in color—notify drivers of unusual or potentially dangerous conditions near work areas.

Channeling Devices:

These include barricades, vertical panels, drums and cones. These devices alert drivers of unusual or potentially dangerous conditions on the roadway and in work zones. These devices may be equipped with warning lights at nighttime and stripes on barricades and panel devices slope downward in the direction traffic must travel.

Flashing Arrow Panels:

Used both during the day and at night to give advance warning and directional information when it is necessary to move to another lane.

Flaggers:

People who work in roadway construction/maintenance zones to stop, slow, or guide traffic safely through the area. Flaggers wear bright colored/fluorescent vests or jackets and use red flags or signs to direct traffic.
