At what distance should you turn on your turn signal before making a turn?

Turning on your turn signal at least 30 meters (100 feet) before making a turn is correct because it gives adequate notice to other drivers and pedestrians about your intentions. This distance allows for sufficient time for other road users to react, ensuring safety and smooth traffic flow.

Using the signal far enough in advance helps in preventing accidents and miscommunication on the road. It is particularly important in busy or complex environments where other vehicles and pedestrians are present, as it allows them to adjust their behavior in response to your upcoming maneuver.

Though other options suggest shorter distances or signaling at inappropriate times, these do not provide enough warning to others, potentially leading to confusion or collisions. Therefore, signaling 30 meters ahead is established best practice for road safety and complies with road regulations.
