When must you signal before making a turn?

Signaling before making a turn is crucial for ensuring safety and communication on the road. The correct practice is to signal at least 30 meters before making the turn. This distance allows other drivers, pedestrians, and cyclists sufficient time to notice your intention to turn and adjust their actions accordingly. By signaling early, you enhance predictability on the road, which contributes to a safer driving environment.

Signaling just before beginning the turn may not provide ample warning for other road users, potentially leading to confusion or accidents. Similarly, signaling only when other vehicles are present fails to cover situations where there might be pedestrians or cyclists in proximity who also need to be aware of your intentions. Lastly, while signaling when approaching a traffic light is important to indicate your intended action, it does not guarantee that other road users are prepared for a turn if the signal is given too late. Therefore, signaling at least 30 meters before the turn is the best practice for effective road communication and safety.
