Variable Speed Limit Signs (VSLS)

McCain's Variable Speed Limit Sign (VSLS), featuring SWARCO's patented lens technology, allows agencies to adjust the speed limit in response to current road and traffic conditions, such as heavy traffic or adverse weather. Decreasing the risk associated with driving at speeds higher than appropriate in these types of conditions can improve traffic flow and safety. This highly energy efficient sign provides brilliant legibility and a superior luminance ratio resulting in outstanding reliability, quality and usability.
