What is the condition that exterior mirrors should be in?

Exterior mirrors are crucial for safe driving as they provide the driver with visibility of the areas surrounding the vehicle. For mirrors to perform their function effectively, they must be in a state that ensures maximum visibility. When the mirrors are clean, clear, and unbroken, they allow the driver to see approaching vehicles, pedestrians, and other hazards without obstruction. This clarity is essential for making accurate judgments about lane changes, merging, and general awareness of the driving environment.

In contrast, fogged and dirty mirrors would significantly reduce visibility, making it difficult to see clearly what is behind and beside the vehicle. Slightly cracked mirrors may distort the view or create blind spots, which can lead to dangerous driving situations. Missing mirrors altogether would leave the driver without critical visual information, which is vital for road safety. Therefore, the condition of being clean, clear, and unbroken is not just a recommendation but a safety requirement for drivers to ensure they are fully aware of their surroundings while on the road.
