True or false: Dirty headlights can reduce visibility up to 90%.

Dirty headlights can significantly reduce visibility while driving, and it has been noted that their effectiveness can diminish drastically as grime, dirt, and residue build up on the lenses. When headlights are obscured, the light output is decreased, making it difficult for drivers to see clearly at night or in poor weather conditions. This reduction in visibility can indeed be as much as 90%, impacting both the driver's ability to see the road and other drivers' ability to see the vehicle.

Maintaining clean headlights is crucial for optimal driving conditions. Headlights that are not functioning at full capacity can lead to dangerous situations, especially at times when visibility is already compromised, such as during rain, fog, or night driving. Regular cleaning of headlights as part of vehicle maintenance can help ensure they provide the necessary brightness for safe operation. This understanding highlights the importance of vehicle upkeep for safety on the road.
