The 2018 GMC Terrain has a 24-inch windshield wiper on the driver side and a 17-inch wiper on the passenger side. Having proper windshield wipers is crucial for maintaining a clear and unobstructed view while driving. Impaired vision on the road is highly dangerous and is a significant factor in about 90% of all accidents. The primary function of a windshield wiper blade is to ensure that your vision remains unimpeded when driving. If you delay replacing worn-out wiper blades, they are likely to become ineffective. It's essential to have reliable windshield wipers, especially during harsh weather conditions like snowstorms, as that rubber strip plays a vital role in keeping the driver's line of sight clear when it is most needed.
