valgusmärgid

Valgusmärgid, also known as traffic lights or traffic signals, are devices used to control the flow of traffic at intersections and other locations where traffic may conflict. They are typically mounted at a fixed location and are operated by a traffic signal controller. Valgusmärgid use a combination of colored lights to indicate the right of way to different directions of traffic.

The most common colors used in valgusmärgid are red, yellow, and green. The red light indicates that drivers must stop and wait for the green light. The yellow light serves as a caution signal, indicating that the red light is about to come on and that drivers should prepare to stop. The green light indicates that drivers may proceed through the intersection.

Valgusmärgid may also include additional signals, such as flashing yellow or red lights, which indicate that drivers should proceed with caution or stop, respectively. They may also include pedestrian signals, which indicate when pedestrians may cross the street.

Valgusmärgid are an important tool for managing traffic flow and reducing the risk of accidents at intersections. They are typically used in conjunction with other traffic control devices, such as stop signs and yield signs, to ensure the safe and efficient movement of traffic.
