When must you use turn signals while driving?

Using turn signals when changing lanes or turning is crucial for ensuring safe driving practices. Turn signals communicate your intentions to other road users, including drivers, cyclists, and pedestrians. This practice fosters predictability on the road, which is essential for preventing misunderstandings that could lead to accidents.

When you change lanes, activating your turn signal alerts drivers behind and beside you that you are about to shift your vehicle's position. Similarly, when preparing to turn, signaling in advance gives others time to react appropriately, helping maintain overall traffic flow and reducing the risk of collisions.

While other scenarios, such as driving near other vehicles or during nighttime, might necessitate cautious driving, the requirement to use turn signals specifically during lane changes and turns is a fundamental rule of road safety that applies consistently, regardless of the driving conditions or surroundings.
