Getting the Most Visibility From Arrow and Message Boards

A board's job is to be seen and understood early. Placement, brightness, and the right board for the task decide whether drivers react in time.

Boards fail quietly. Nobody notices a message that was too dim or posted too late until a driver reacts too close to the crew. Visibility is not just about a bright display, it is about giving drivers enough distance and a clear instruction.

Pick the right board for the task

• 15-lamp arrow board for lower-speed or shorter closures
• 25-lamp arrow board where you need reach at higher speeds
• Changeable message sign for detours, speed advisories, and crew warnings

An arrow board tells drivers where to go; a message sign tells them why and what to do. On bigger closures, run both so the direction and the reason reinforce each other.

Placement and brightness

Put the board far enough upstream that drivers can read it and change lanes without braking hard. Keep lamps clean and lenses clear so the display holds up in direct sun, and confirm the board reads at night under headlights. A board that is bright at the shop but aimed wrong on the road does the crew no good.
