How long should you signal before changing lanes?

When changing lanes, it is important to signal for a sufficient distance to inform other drivers of your intention. Signaling at least 100 feet before making a lane change allows other drivers adequate time to react. This distance is standard in many states, including Georgia, to ensure safety on the road by increasing visibility and reducing the risk of accidents. A signal informs other drivers, which is essential for maintaining safe traffic flow.

Options that suggest shorter distances, such as 50 feet, may not provide enough warning for other drivers, while longer distances might be excessive in certain situations. Thus, 100 feet strikes a balance, ensuring effective communication without causing unnecessary delays in traffic.
