What is a requirement for the glass used in windows?

The requirement for glass used in windows being that it must be constructed of good material and be clear is essential for several reasons. Firstly, good quality glass ensures durability and strength, which are crucial for safety and longevity in various weather conditions. Clear glass provides the necessary visibility for drivers to see clearly through the windows. This is particularly important for ensuring safe navigation and awareness of surroundings while driving.

Using good quality, clear materials allows for a clearer view, reducing visual obstructions and potential hazards on the road. This not only enhances the aesthetic aspect of the vehicle but also plays a critical role in the functionality of the driver's field of vision. In contrast, options that suggest tinting, opacity, or that glass should shatter easily do not meet the safety and visibility requirements essential for road use.
