Using your turn signals is only optional when:

• A. None of the above.
• B. Changing lanes when no one is around.
• C. Returning to your lane after passing another vehicle.
• D. Merging into the flow of traffic under 25 mph.

Answer: (A)

Signaling is a key safety communication that tells other drivers your intended move. In CDL practice, you must use your turn signal before any lane change, before merging, and before returning to a lane after passing. There are no exceptions here—none of these scenarios make signaling optional. Even when the road seems empty, signaling helps others anticipate your actions and prevents surprises that could cause a crash. So there are no valid times when you can skip signaling in these maneuvers. Always signal ahead of the maneuver and keep your signal clear and active long enough for others to notice.
