How far ahead should you signal before making a turn?

Signaling your intention to turn is an essential part of safe driving practices, as it communicates your next move to other road users. Signaling at least 30 meters before making a turn provides ample notice for surrounding vehicles and pedestrians to react appropriately. This distance gives other drivers enough time to understand your intentions and adjust their speed or position if needed, enhancing overall safety on the road.

A distance of 10 meters may not provide enough time for drivers behind you to respond, especially at higher speeds, potentially leading to collisions. While signaling immediately before the turn might alert nearby drivers too late, creating a hazardous situation. Signaling 50 meters, while it may seem safer, is usually unnecessary and could lead to confusion, particularly in urban areas with many potential distractions. Therefore, signaling at least 30 meters strikes a good balance between alerting others and providing a clear and predictable driving pattern.
