How far in advance should you signal before making a turn?

Signaling at least 100 feet before making a turn is essential for safety and communication with other drivers on the road. This allows ample time for other vehicles and pedestrians to be aware of your intentions, reducing the risk of accidents. The distance gives drivers following you enough time to react appropriately if needed, either by slowing down or preparing to pass.

In urban areas or near intersections, this 100-foot signal distance is typically effective because it ensures that your intentions are clear, allowing other road users to anticipate your movements. It's important to establish a routine of signaling early to maintain safe driving practices and promote predictability on the road.

The other distances mentioned, like 50 feet or 200 feet, may not provide enough notice for others or could be excessive based on the driving environment, respectively. Signaling only at the intersection might lead to confusion and potential hazards, as it doesn't adequately inform other road users in advance of your actions.
