Features

Blank Out Signs (BOS) are the best possible type of sign to convey simple messages to all drivers. They are designed to be very easy to use. The display has only two options: Message ON or Message OFF with several brightness levels. They are ideal to indicate traffic patterns, to alert danger, and to convey specific instructions to drivers.

Blank Out Signs improve traffic safety. Studies demonstrate that traffic safety is highly improved when BOS are used for pedestrian awareness, rail crossing, dangerous curve signalization, flood warning systems, weigh station driving instructions, etc.
