Answer: C — To communicate upcoming turns and lane changes

Turn signals serve the crucial function of communicating a rider's intentions to other drivers on the road. By using turn signals, a motorcyclist can indicate upcoming turns, lane changes, or other maneuvers. This clear communication is essential for maintaining safety on the road, as it helps prevent accidents by ensuring that surrounding vehicles are aware of what the motorcyclist plans to do next. Proper use of turn signals allows for smoother traffic flow and enhances overall road safety, as drivers can anticipate each other's actions more accurately.
