Why should you replace a scratched helmet visor?

Your answer correctly identified both crucial reasons for replacing a scratched helmet visor: restricted vision and increased glare. According to German traffic regulations, it is essential to maintain clear visibility while riding to ensure safety. A scratched visor can obstruct the rider's view and make it difficult to see other vehicles, road signs, or hazards. Additionally, scratches can cause increased glare from sunlight, further impairing vision and reaction time.

The third option, regarding the visor becoming more misted up, also plays a significant role in safety. If the visor is compromised, it may not handle moisture well, leading to fogging that can further restrict visibility. Although your answer included the key points, recognizing all three reasons provides a more comprehensive understanding of the importance of wearing an undamaged helmet visor while riding.
