What is the proper way to signal to change lanes?

The correct approach to signaling a lane change involves signaling early and changing lanes slowly and smoothly. This practice is crucial for ensuring safety on the road. When you signal early, you give other drivers adequate notice of your intentions, allowing them to react appropriately, which contributes to overall traffic safety. Changing lanes slowly and smoothly also helps maintain control of the vehicle and minimize the risk of a collision.

Moving over too quickly, as suggested in one of the other options, may surprise other drivers and increase the risk of an accident. Additionally, signaling just as you begin to change lanes compromises communication with other drivers, leading to confusion and unsafe conditions. It’s essential to maintain a clear and predictable driving pattern, which is why the earlier and smoother signaling method is the best practice for lane changes.
