Mobile variable message signs are designed for fast deployment and temporary use. Typical applications include traffic redirection during roadworks, urgent weather information (fog, heavy rain, snowfall, ice), when clearing wrecks after an accident, for managing traffic flow during major sporting events and disaster situations (fire, explosions, natural disasters), etc.

With its high brightness and contrast, a mobile variable message sign attracts drivers' attention much more effectively than static traffic signs. As a result, it is more efficient in situations when fixed sign messages should be disregarded by road users.Mobile variable message signs are invaluable for road maintenance teams and police to control traffic in emergency situations to ensure the best possible level of service and traffic flows.
