The purpose of a rear wiper on a vehicle is to provide visibility and maintain a clear rear window in situations where it may become obstructed or dirty. While the primary purpose of the front windshield wipers is to clear the front windshield from rain, snow, or other debris, the rear wiper serves a similar function for the rear window.
Rain and Wet Conditions: In wet weather, rain can accumulate on the rear window, impairing visibility for the driver. The rear wiper helps clear away the water, allowing the driver to see clearly through the rear window.
Snow and Ice: In snowy or icy conditions, the rear window can become covered in snow or frost, making it difficult to see. The rear wiper can remove the snow or ice, improving visibility and safety.
Dirt and Dust: The rear window can also become dirty or covered in dust, particularly during off-road driving or in dusty environments. The rear wiper can help remove these particles, allowing for better visibility.
Backup and Reversing: When reversing a vehicle, especially in tight spaces or while parking, having a clear view through the rear window is crucial. The rear wiper ensures that the window remains clean and unobstructed, aiding in safe maneuvering.
Safety: Maintaining good visibility is essential for overall driving safety. A clear rear window helps the driver monitor traffic conditions behind the vehicle and be aware of any potential hazards or obstacles.
It's worth noting that not all vehicles come equipped with rear wipers. Smaller cars or certain vehicle models may not have them, as rear visibility might be considered sufficient without one. However, in situations where visibility can be compromised, the rear wiper becomes a valuable feature.
