näkyvyyssääntöjä

Visibility rules, or näkyvyyssääntöjä in Finnish, refer to regulations designed to ensure that vehicles and individuals can see and be seen by others, particularly in traffic situations. These rules are crucial for preventing accidents by maintaining situational awareness.

In the context of road traffic, visibility rules dictate aspects such as the use of headlights, the condition of vehicle lights, and the clearing of obstructions like snow or ice from windows. They also encompass regulations regarding the placement of parked vehicles to avoid obstructing the view of other road users. Pedestrian visibility is also addressed, often through recommendations or requirements for reflective clothing in low-light conditions.

Maritime visibility rules, often governed by the International Regulations for Preventing Collisions at Sea (COLREGs), involve the use of navigation lights to indicate a vessel's status, direction, and proximity to other vessels during periods of restricted visibility such as fog. They also include rules for sound signals to alert others to a vessel's presence.

In aviation, visibility rules are paramount for safe flight operations. These rules define the minimum distances at which aircraft can be seen from each other and from the ground, influencing air traffic control procedures and pilot responsibilities. They also dictate when aircraft lights must be used.

The overarching goal of all visibility rules is to enhance safety by ensuring that all parties involved in an activity can perceive potential hazards and react appropriately, thereby minimizing the risk of collisions and other incidents.
