When must you signal a turn?

Answer: A — At least 100 feet before the intersection

Signaling a turn at least 100 feet before reaching the intersection is crucial for several reasons. Firstly, it provides adequate notice to other drivers, cyclists, and pedestrians of your intentions, which enhances overall road safety. This advance notice allows others to anticipate your actions and react accordingly, helping to prevent potential accidents. In many jurisdictions, including Illinois, the law requires using turn signals a specified distance before making a turn. This distance—typically around 100 feet—ensures that drivers have enough time to respond to your signal in a timely manner. Additionally, signaling well in advance promotes better communication on the road, fostering a culture of caution and awareness among all road users. This practice contributes to the smooth flow of traffic and minimizes the risk of confusion or misjudgment by other drivers. Adhering to this rule is part of safe driving behavior and helps you comply with driving regulations.
