When should a driver signal their intention to turn?

A driver should signal their intention to turn at least 100 feet before making the turn to ensure that other road users are aware of their intentions. This early indication is crucial for safety, as it provides enough time for other drivers, cyclists, and pedestrians to react accordingly. Signaling well ahead of the turn helps maintain smooth traffic flow, reduces confusion, and minimizes the risk of accidents.

While other situations like changing lanes also require signaling, the focus of this question is specifically on turning. The requirement to signal only when arriving at the junction does not allow sufficient time for other road users to adjust their actions, which could lead to dangerous situations. Similarly, signaling only if there is traffic behind the vehicle neglects the importance of informing all road users of the driver’s intentions, regardless of their position.
