What is a requirement for vehicle wipers?

A vehicle's wipers must have all functioning properly to ensure optimal visibility for the driver. This requirement is critical for safety, as effective windshield wipers are essential for clearing rain, snow, and debris from the windshield, allowing the driver to maintain clear visibility during adverse weather conditions. If any wiper is malfunctioning, it can create blind spots or obstructed views, significantly increasing the risk of accidents.

While having at least one working wiper might seem sufficient, the requirement goes further to ensure all wipers effectively contribute to overall vehicle safety. Maintaining all wipers in good working condition addresses various environmental factors that might affect driving, leading to safer travel experiences.
