How many feet before making a turn or lane change must you display a turn signal?

Displaying a turn signal is an important aspect of safe driving, as it communicates your intentions to other road users, thereby enhancing overall safety and reducing the risk of accidents. In Hawaii, the law requires drivers to signal at least 100 feet before making a turn or lane change. This distance allows other drivers and pedestrians sufficient time to react to the change in your path, facilitating smoother traffic flow and ensuring everyone on the road can anticipate movements safely.

The requirement for 100 feet is designed to account for various driving conditions, including speed limits and traffic density, thus ensuring the signal is visible to those around you well in advance of the maneuver. This standard aligns with best practices for safe driving, emphasizing proactive communication on the road.
