What is the correct way to use turn signals?

Using turn signals correctly is essential for safe driving and communicating your intentions to other road users. Signaling at least 100 feet before making a turn or lane change is the appropriate practice because it provides sufficient notice to both drivers and pedestrians about your intended action. This allows others to make any necessary adjustments, such as slowing down or changing their position on the road, which contributes to a smoother and safer flow of traffic.

The 100-foot guideline helps ensure that your signal is viewed by those who might be affected by your maneuver, providing them adequate time to react. This is particularly important in areas with higher traffic volumes or speed limits where actions need to be predictable and timely to prevent accidents.

Moreover, signaling immediately before making a turn does not allow enough time for others to react, and failing to signal when no one is around can lead to habits that might cause problems in different scenarios, such as when other vehicles or pedestrians suddenly appear. Consistent signaling, regardless of other road users, promotes responsible driving behavior and enhances road safety.
