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

Turning on your turn signal at least 100 feet before making a turn is crucial for ensuring the safety and awareness of other drivers on the road. This distance allows sufficient time for other motorists and pedestrians to notice your intention to change direction. By signaling your intent early, you contribute to better traffic flow and reduce the risk of unexpected movements that could lead to collisions.

The recommendation of 100 feet is based on the average perception and reaction times of drivers. It ensures that other vehicles can adjust their speed or position as necessary, making it easier for everyone on the road to anticipate the turn. Signaling at this distance helps promote safe driving habits and complies with traffic regulations, making it a fundamental aspect of defensive driving.

Choosing a shorter distance might not provide enough time for surrounding drivers to react, while longer distances may not be practical in every situation, particularly in urban settings where turns are frequent. Thus, 100 feet strikes a balance, allowing for adequate warning while being realistic for typical driving conditions.
