What is the basic rule for using turn signals in California?

• A. Signals are optional
• B. Turn signals must be used only at intersections with traffic lights
• C. Use turn signals for all turns and lane changes, and cancel when the maneuver is complete.
• D. Use only for right turns

Answer: (C)

Communicating your intended movement to other road users is essential for safety. You should use turn signals for every turn and for every lane change, and you must keep the signal on for the entire maneuver and cancel it once you’ve completed the action. This helps other drivers and riders anticipate what you’re about to do, reducing surprises and the chance of a collision. In California, signaling clearly and consistently is expected for all turns and lane changes, not just some of them or only in certain locations. If your signals aren’t working, you should use hand signals as a backup to convey your intent.
