When should you use your turn signals?

• A. Only when turning into a driveway.
• B. Well before the maneuver, including lane changes, merging, or turning.
• C. Only after you have begun the maneuver.
• D. Signals are optional in light traffic.

Answer: (B)

Signaling early communicates your intentions to other drivers, giving them time to react and adjust their speed or position. The best practice is to activate your turn signal well before you begin any maneuver that changes your path—whether you’re turning, changing lanes, or merging. This forewarning helps prevent surprise moves that can lead to collisions. Keep the signal on for the entire maneuver and for a moment after you’ve completed it, and cancel it once you’re back in your lane or have finished turning. This isn’t optional in light traffic; using signals consistently reduces risk for everyone on the road. The other options miss the important idea of forewarning and timing: signals should not be used only after you’ve started, only when turning into a driveway, or not used at all in light traffic.
