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

Signaling at least 100 feet before making a turn is advisable because it provides sufficient notice to other drivers and pedestrians of your intended action. This distance is particularly important in urban settings where traffic can be more congested, allowing other road users to adjust their behavior accordingly and enhancing overall safety. By signaling early, you create a clearer communication of your intentions, which helps in reducing the likelihood of accidents. This timing allows drivers behind you to understand that you are planning to slow down or change lanes, thereby improving the flow of traffic and minimizing confusion.
