When must you signal?

You answered correctly. You must signal before pulling out to overtake or pass, and also before returning to your lane after overtaking. This is required to inform other road users about your intentions and ensure safety. However, signaling is not required when going straight ahead off a priority road that bends sharply, unless you are actually changing direction. Always use your turn signal to clearly indicate any lateral movement or lane change on the road. This helps prevent misunderstandings and potential accidents.
