How many feet before making a turn is a driver required to signal?

Drivers in Pennsylvania are required to signal their intentions to turn at least 100 feet before making the actual turn. This distance ensures that other drivers and pedestrians are given sufficient notice of the driver's intent to change direction, enhancing safety on the road. Signaling early allows other road users to react appropriately—whether that means slowing down, stopping, or adjusting their own movements—contributing to the overall flow of traffic and reducing the likelihood of collisions. By following this guideline, drivers demonstrate responsible and safe driving behavior, making the roads safer for everyone.
