What is a "turn signal"?
A turn signal is a light on a vehicle that indicates the driver’s intention to turn or change lanes. It is activated by a lever, typically located near the steering wheel, which makes the signal flash on and off. The turn signal helps other drivers understand the vehicle’s movements, improving safety by providing clear communication. It can be used to signal a left or right turn or a lane change. The turn signal should be used in advance of making a turn or changing lanes to give other drivers time to react.
Examples
Before merging into the next lane, she activated her turn signal to alert other drivers.
The driver forgot to use the turn signal, causing a nearby car to slow down abruptly.
