How many feet before making a turn should a driver signal at an intersection?

A driver should signal at least 100 feet before making a turn at an intersection. This distance is designed to give other road users, including drivers and pedestrians, ample time to anticipate the driver's actions. Signaling well in advance helps ensure safety by allowing others to adjust their speed or position accordingly, reducing the risk of accidents.

In urban areas or situations where traffic is heavy, signaling early also helps keep the flow of traffic smooth. Additionally, it provides clarity to other drivers about your intentions, minimizing confusion on the road.

The specific requirement of 100 feet is based on common practice and guidelines set forth in driving regulations, which promote responsible and safe driving behaviors.
