When must you use your turn signal?

Answer: B — Anytime you plan to turn or change lanes

Using a turn signal is a critical component of safe driving as it communicates your intentions to other road users. Anytime you plan to turn or change lanes, signaling in advance allows others to anticipate your actions, helping to prevent collisions. The law requires drivers to signal their intentions to ensure the safety of all road users, not just when other vehicles are nearby. This practice should be followed regardless of conditions such as weather or time of day. By signaling consistently, you contribute to a predictable driving environment, which enhances overall traffic safety.
