When should you use turn signals?

• A. Use signals whenever changing lanes, merging, or turning, well before the maneuver.
• B. Use signals only when turning at intersections.
• C. Use signals after you start the maneuver.
• D. Signals are optional in light traffic.

Answer: (C)

Signaling before you act communicates your intended move to other road users, giving them time to adjust and respond. You should use turn signals whenever you plan to change lanes, merge, or turn, and do so well before you begin the maneuver. This early notice helps drivers, bicyclists, and pedestrians anticipate your actions, reducing surprises and making traffic safer. Signaling after you start the maneuver is too late to warn others, and signaling only at intersections misses chances to preview lane changes or merges. Signals aren’t optional, even in light traffic. Keep the signal on through the maneuver until it’s completed.
