Every vehicle is outfitted with a variety of devices to help drivers navigate safely during their travels. These devices include the basics such as steering wheel, headlights, gas and brake pedals, seat belts, air bags, and so on. Also included, although often overlooked, is the turn signal, or "blinker."

The purpose of a turn signal is to let drivers tell others of their intentions to change lanes or turn to minimize hazardous surprises and help prevent accidents.

Although the turn signal lever is conveniently located within mere inches of the steering wheel, countless drivers fail to use it. While it is rarely enforced, use of turn signals is required by law in most jurisdictions. For example, in the state of New York, drivers are required to use turn signals continuously during not less than the last 100 feet traveled by the vehicle before turning.

However, many drivers incorrectly treat the use of turn signals as a voluntary act that is left to the discretion of the vehicle operator. This is unfortunate for other drivers on the road
