The rearview mirror is a flat mirror installed inside a vehicle, typically positioned at the centre above the windshield. Its primary function is to enable the driver to observe rear traffic conditions without turning their head, making it one of the core components of passive safety systems. Some models also incorporate automatic anti-glare or digital display functionalities. Modern rearview mirror designs must comply with international safety standards such as UN ECE R46 to ensure parameters like mirror curvature and field of vision meet road safety requirements. Certain high-end models integrate rearview cameras to form 360-degree surround-view systems, though traditional optical rearview mirrors remain standard equipment for vehicles sold in Malaysia. Correctly adjusting the rearview mirror angle can eliminate approximately 30% of rear blind zones. It is best to position the mirror so that a slight portion of the vehicle's own rear fender is just visible-an optimized solution balancing maximum visibility and spatial orientation.
