How far in advance should you signal before turning?

Answer: B — At least 5 seconds before the turn

Signaling at least 5 seconds before making a turn is essential for ensuring safety and proper communication with other road users. This timing allows ample opportunity for approaching vehicles, cyclists, and pedestrians to interpret your intent and adjust their behavior accordingly. The 5-second rule provides enough notice for drivers and others on the road to react appropriately, helping to prevent accidents and promote smooth traffic flow. This duration is generally considered a good balance between giving sufficient warning and not signaling too early, which could cause confusion regarding your actual intended maneuver. The intent behind signaling is to promote awareness and predictability on the road, making it crucial for effective road safety. By adhering to this practice, drivers contribute to a safer driving environment for everyone.
