How far in advance should you signal your intention to turn?

Signaling your intention to turn at least 30 meters (or 100 feet) before making the maneuver is important for safety and effective communication on the road. This distance gives other drivers, cyclists, and pedestrians ample time to understand your intentions, allowing them to adjust their actions accordingly. Early signaling is crucial, especially in busy or high-speed environments where reactions need to be timely.

By alerting others of your intended turn, you minimize the risk of collisions and contribute to a smoother flow of traffic. The recommended distance also takes into account the visibility of your signal; it needs to be clear enough for others to see well in advance of your actual turn.

Signaling only when reaching the stop line or when seeing the turn ahead does not provide adequate warning to others and can lead to unsafe situations. Failing to signal early can cause confusion among other road users and increase the likelihood of an accident.
