How far ahead should you signal before making a turn?

Answer: B — At least 30 meters

Signaling at least 30 meters before making a turn is essential for the safety of all road users. This distance gives sufficient warning to drivers and pedestrians about your intention to turn, allowing them to react appropriately. It provides enough time for vehicles following behind to adjust their speed or position, ensuring a smoother flow of traffic and reducing the risk of collisions. In urban settings or when driving at lower speeds, signaling 30 meters ahead is typically adequate, as it can effectively convey your intentions without being overly cautious. Maintaining this distance is particularly important in situations where visibility might be reduced or where other vehicles and pedestrians are nearby. A shorter distance, such as 10 meters, might not give adequate time for drivers behind you to respond, while options that suggest 50 or 100 meters could be excessive in many urban scenarios, potentially leading to confusion among drivers about your intended actions. Therefore, the 30-meter guideline strikes a good balance for effective communication on the road.
