Signaaltuled

Signaaltuled, commonly known as traffic lights, are signaling devices positioned at road intersections, pedestrian crossings, and other locations to control competing flows of traffic. They typically consist of three lamps arranged vertically or horizontally: red, amber (yellow), and green. Each color has a specific meaning to guide drivers and pedestrians.

The red light indicates a stop command, meaning all traffic facing the light must come to a complete halt behind the stop line. The amber light serves as a warning, signaling that the light is about to change to red. Drivers should prepare to stop if it is safe to do so, or proceed with caution if they are already in the intersection or too close to stop safely. The green light signifies permission to proceed, but only if the intersection is clear and it is safe to do so.

Signaaltuled are crucial for road safety, helping to prevent collisions by regulating the right-of-way. They are an integral part of modern traffic management systems, contributing to smoother traffic flow and reduced congestion. Different countries and regions may have minor variations in the specific rules or the duration of light cycles, but the fundamental principles of red, amber, and green remain consistent worldwide. Pedestrian signals, often integrated with traffic lights, use simplified symbols like a walking person (green) and a hand (red) to guide pedestrians across roadways safely.
