When should a driver use their turn signal?

Using a turn signal is essential for ensuring safe and effective communication with other road users. The correct answer is that drivers should signal before making turns or lane changes. This practice allows other drivers, cyclists, and pedestrians to anticipate an upcoming maneuver, reducing the likelihood of confusion or accidents.

Signaling before executing a turn or lane change provides vital information about your intentions on the road. For instance, when you approach an intersection and plan to turn left or right, activating your turn signal alerts others to your action well in advance, enabling them to adjust their behavior accordingly. Similarly, when changing lanes, signaling gives other drivers notice that you intend to shift your position, which can help prevent collisions.

The importance of using turn signals applies universally, regardless of traffic conditions or the type of maneuver being performed. While other scenarios, such as crossing intersections or driving in heavy traffic, are relevant to consider, they don't negate the necessity of using signals when turns or lane changes are about to happen. Thus, making signaling a consistent practice contributes to overall road safety.
