When changing lanes on a multi-lane highway, when should you signal your intentions?

Signaling your intentions at least 100 feet before changing lanes is crucial for ensuring safety on the road. This practice allows other drivers adequate time to become aware of your intended movement. It gives them a chance to adjust their speed or position accordingly. Recognizing a turn signal well in advance is important for maintaining traffic flow and preventing sudden lane changes that could lead to accidents.

In many jurisdictions, including Hawaii, signaling well in advance is not only a best practice but often a legal requirement. It emphasizes the responsibility of drivers to communicate their actions to others on the road. This proactive approach fosters awareness and reduces the risk of collisions, making it a fundamental aspect of safe driving.
