When must you signal your intent to turn?

Answer: B — At least 100 feet before the turn

In Illinois, you must signal your intent to turn at least 100 feet before making the turn. This distance is designed to give other road users ample time to react to your actions, thereby enhancing safety for everyone on the road. By signaling well in advance, you provide clear communication about your intentions, which can help prevent misunderstandings or collisions. This practice is particularly important in busy areas where other vehicles, pedestrians, or cyclists may be present. Signaling at the proper distance ensures that those around you can safely adjust their speed or direction in response to your upcoming maneuver.
