What is the minimum visibility requirement for the rear window?

The minimum visibility requirement for the rear window is designed to ensure that drivers can safely operate their vehicles by having a clear line of sight behind them. The requirement for visibility up to 200 feet ensures that when a driver looks through the rear window, they can see other vehicles and obstacles from a sufficient distance, which is critical for safe reversing and merging maneuvers.

A clear rear view contributes significantly to overall vehicle safety, as it helps in avoiding accidents caused by unseen objects or vehicles approaching from behind. This visibility standard is an important aspect of vehicle inspections to confirm that the rear window is not obstructed or excessively tinted beyond legal limits. By setting the requirement at 200 feet, it provides a standard that reinforces safety for both the driver and other road users, ensuring that visibility is ample enough to plan and react appropriately to the driving environment.

The other options suggest insufficient visibility distances, which could compromise safe driving. Hence, the requirement of 200 feet is the minimum standard established to ensure adequate visibility through the rear window.
