What is the allowable height for a vehicle's windshield wipers?

Windshield wipers are essential for maintaining a clear line of sight for the driver during inclement weather, which is crucial for safety on the road. The requirement that wipers must adequately clear the driver's view emphasizes the importance of functionality over a specific height threshold. This focuses on ensuring that the wipers operate effectively to remove rain, snow, or debris from the windshield, thereby providing optimal visibility.

While there may not be a specific measurement in terms of height that is mandated for wipers, the critical factor is that they must perform their intended function of clearing the driver's view without obstruction. This reflects a practical approach to vehicle safety standards, prioritizing real-world performance over rigid specifications that don’t necessarily guarantee adequate visibility.
