suuntavilkkua

Suuntavilkkua, commonly known as a turn signal or blinker, is a safety device on road vehicles used to indicate an intended change of direction. These are typically flashing lights, usually amber in color, mounted on the front, rear, and sometimes sides of a vehicle. When the driver activates a lever or button, the suuntavilkkua illuminates intermittently, alerting other road users to the vehicle's impending maneuver, such as turning at an intersection or changing lanes.

The operation of the suuntavilkkua is usually connected to the steering column. Moving the lever in one direction activates the turn signal on that side of the vehicle, and it typically deactivates automatically after the turn is completed or when the steering wheel returns to a straight position. In some cases, manual deactivation is required. The flashing rate is standardized to ensure visibility and audibility, often accompanied by an audible clicking sound inside the vehicle.

Proper use of the suuntavilkkua is a fundamental aspect of safe driving and is legally mandated in most jurisdictions. It helps prevent collisions by providing clear communication between drivers. Failure to use turn signals correctly can lead to misunderstandings and accidents. The technology has evolved over time, with some modern vehicles incorporating LED technology for brighter and more durable suuntavilkkua, and even some automatic signaling features.
