Which statement about signaling when preparing to change lanes is correct?

• A. Turn on your turn signal as soon as possible without creating confusion
• B. Use the turn signal only after starting to move
• C. Turn signals are optional in all driving situations
• D. Use the horn instead of a turn signal to indicate lane changes

Answer: (A)

Signaling early when preparing to change lanes is essential because it communicates your intent to other drivers, giving them time to slow down or adjust position and making the merge predictable. Turn on your turn signal as soon as you decide to move, before you begin the lane change, so the traffic around you has a warning and can respond safely. If you wait until you start moving to signal, drivers behind you may not see your intent in time, increasing the chance of a close call. Signaling is not optional; using a turn signal is the proper, legal way to indicate a lane change. The horn is not a substitute for a signal—the horn is for emergencies or to warn of immediate danger and can startle others. So use the signal early, keep it on until you have completed the lane change, and cancel it after you are safely in the new lane.
