Sumuverhojen

Sumuverhojen refers to a type of warning device used in Finland, particularly in the context of forestry and roadwork. The term "sumuverhojen" is derived from Finnish, where "sumu-" means fog and "verhojen" means veils or mists. This device is designed to provide visibility and warning to motorists and other road users in low-visibility conditions such as fog.

The system of sumuverhojen consists of a series of poles equipped with reflective or light-emitting strips. These devices can be secured to trees, utility poles, or other existing infrastructure along roadsides, particularly in areas prone to fog. The use of sumuverhojen is considered particularly necessary during periods of winter weather in regions with high humidity and temperature differentials.

Finnish authorities and transportation agencies have mandated the use of sumuverhojen on highways and other roads during periods of heavy fog. These devices increase visibility for road users by providing a series of high-visibility beacons along the road, enabling them to adjust their speed and navigation accordingly.

As part of Finnish safety protocols, sumuverhojen are frequently used in conjunction with fog warning systems, such as automatic warning signs and variable speed limit signs. These integrated systems enable transportation agencies to issue warnings to motorists and inform them of impending reduced visibility conditions, thus minimizing the risk of accidents caused by reduced visibility in adverse weather conditions.

The system aims to strike a balance between providing motorists with sufficient warning and minimizing disruptions to normal traffic flow. Sumuverhojen are a notable example of a unique solution to improve road safety in environments characterized by fog and reduced visibility.
