What is the purpose of a motorcycle's mirrors?

The primary purpose of a motorcycle's mirrors is to provide the rider with a view of the traffic behind them. This is crucial for safe riding, as it allows the motorcyclist to be aware of their surroundings, particularly vehicles approaching from behind, which can help in making informed decisions when changing lanes or merging into traffic. Being able to see what is happening behind is an essential aspect of safe riding, as it significantly reduces the risk of accidents caused by a lack of situational awareness.

While mirrors may contribute to the aesthetic of a motorcycle, they play a much more critical role in ensuring safety and control, which is their primary function. Monitoring tire pressure or assisting with navigation are not functions that mirrors perform; these tasks require different tools or instruments. Therefore, the ability to see traffic approaching from behind is the key reason mirrors are a vital feature on motorcycles.
