When must turn signals be used while driving?

Using turn signals is critical for safe driving as it communicates your intentions to other road users. When changing lanes or making a turn, signaling at least 100 feet in advance is necessary because it gives other drivers adequate time to react to your actions. This distance helps to ensure the safety of both your vehicle and others on the road, as it allows for a smooth and predictable flow of traffic.

Signaling too late can lead to confusion and potential accidents, as other drivers may not have enough time to respond appropriately to your planned maneuvers. The 100-foot guideline helps promote awareness and reduces the risk of collisions. Therefore, using turn signals well in advance is an essential practice to maintain safety and courtesy on the road.
