You should regularly check your helmet visor. Why should you replace it if it is scratched?

You answered correctly because a scratched helmet visor can impair your vision and cause glare, especially in low-light or nighttime conditions. This is important for safety, as clear and unobstructed vision is essential when riding. If the visor is scratched, it can distort light and reflections, leading to distraction or partial blindness, making it harder to see the road, other vehicles, or obstacles. The rule emphasizes replacing the visor to maintain optimal visibility and prevent being dazzled, ensuring your safety while riding. The third option is incorrect because identification of your face is not the primary purpose of the visor; safety and clear vision are the key reasons.
