When should a motorcyclist use their turn signals?

Answer: B — Before every turn or lane change

A motorcyclist should use their turn signals before every turn or lane change to communicate their intentions to other road users. This practice enhances safety by ensuring that drivers, pedestrians, and other motorcyclists are aware of the rider's movements, helping to prevent accidents. Proper signaling is a critical part of defensive driving, as it provides clear and consistent communication, thus reducing confusion on the road. Relying only on traffic conditions, as suggested by other options, can lead to dangerous situations. Not using signals at intersections or only when a rider feels it is necessary can create misunderstandings with other road users, further increasing the risk of accidents. Therefore, consistent use of turn signals acts as a proactive measure to maintain safety and predictability in traffic.
