In professional terminology, rearview mirrors are usually referred to as "rearview mirror" or "rear-view mirror", which are their most standard English expressions. Additionally, they may also be called "side mirror" (for side-view mirrors), "backup mirror" (for reversing mirrors), or "driving mirror" depending on their specific types and functions. Technically, rearview mirrors constitute a critical component of a vehicle's safety system, primarily categorized into interior rearview mirrors and exterior rearview mirrors. Modern vehicles commonly feature intelligent rearview mirrors equipped with functionalities such as power adjustment, heating and defogging, and automatic anti-glare. Some premium models even incorporate electronic rearview mirror technology, replacing conventional mirrors with camera-display systems. For daily maintenance, it is advisable to routinely inspect the adjustment angle and cleanliness of the mirrors to ensure clear visibility of road conditions within approximately 200 meters behind the vehicle-a vital requirement for manoeuvres like lane changes and reversing. Additionally, drivers should remain mindful of blind spots associated with exterior rearview mirrors and may consider installing wide-angle auxiliary mirrors when necessary.
