What is the proper way to use turn signals when changing lanes?

Using turn signals properly is crucial for safe driving, particularly when changing lanes. Signaling at least 100 feet before changing lanes provides other drivers with ample notice of your intentions. This distance allows them to react appropriately, reducing the risk of accidents caused by sudden lane changes.

In most driving situations, particularly in a commercial driver's context, it's important to ensure that other road users are aware of your movements well in advance. This distance is typically considered sufficient for others to recognize that you intend to change lanes, making it a standard practice in safe driving.

While shorter distances like 50 feet may seem appropriate, they do not provide enough warning for other drivers, especially in faster-moving lanes or heavy traffic. It is also essential to realize that failing to signal or signaling too late can lead to confusion and potential collisions. Therefore, signaling at least 100 feet before a lane change is the recommended and safest practice.
