What is the function of turn signals on a motorcycle?

The function of turn signals on a motorcycle is to indicate lane changes and turns. This is crucial for safety on the roadway, as it communicates the rider's intentions to other drivers and pedestrians. By using turn signals, a motorcyclist can clearly signify that they are about to change lanes or make a turn, allowing others to anticipate their actions. This helps to prevent accidents and promotes safe riding habits by ensuring that everyone on the road is aware of the motorcyclist's movements.

In contrast, the other options highlight functions that are not the primary purpose of turn signals. For instance, turn signals do not indicate braking, illuminate the road, or signify when the engine is running. Understanding the specific function of turn signals reinforces the importance of using them correctly as part of safe riding practices.
