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

Turning on your turn signal at least 100 feet before making a turn is crucial for ensuring safety and maintaining proper communication with other road users. This distance provides enough time for drivers around you to perceive your intention to turn and react accordingly, which is especially important in busy traffic conditions.

Signaling at this distance helps prevent confusion and reduces the risk of accidents, allowing following vehicles to adjust their speed or positioning if necessary. The guideline of 100 feet is based on average stopping distances and reaction times, ensuring that your actions are clear to others on the road well in advance of your maneuver.
