Wipers are essential components of vehicles, designed to keep the windshield clear of rain, snow, and debris. They consist of a rubber blade attached to a metal arm that moves back and forth across the glass. This movement helps maintain visibility for drivers, ensuring safety during adverse weather conditions. In addition to cars, wipers are also found on other vehicles like buses and trucks, as well as on machinery such as tractors and construction equipment. Some modern vehicles even feature advanced wiper systems that automatically adjust their speed based on the amount of rain detected, enhancing convenience for drivers.
