How often are the wipers changed?

t is reported that 20% of accidents caused by visually impaired accidents are caused by dirty or water-stained windshields. At any given time, industry estimates suggest that 50% of vehicles in operation tend to exceed their functional life span. In general, the wipers should be tested every six months and replaced as soon as the field of view of the windshield is reduced. Car manufacturers usually recommend replacing wipers after 12 to 18 months. New wipers are such an important safety component that many European regions have laws requiring them to be replaced every 12 months.
