How far in advance should you signal when changing lanes?

When changing lanes, signaling at least 100 feet in advance is important for ensuring safety on the road. This distance provides adequate time for other drivers to be alerted to your intention to change lanes, enabling them to adjust their speed or position if necessary. Signaling early also gives you time to observe surrounding traffic and make a safe maneuver, minimizing the risk of collisions.

Signaling too late can lead to confusion for other drivers, as they may not anticipate your lane change in time. This distance is a standard recommended practice, as it allows for clearer communication on the roadway and contributes to a safer driving environment for everyone.
