Under what condition must shaded lenses be worn?

• A. During nighttime driving
• B. After sunrise and before sundown
• C. Only on weekends
• D. While operating buses only

Answer: (B)

Shaded lenses must be worn after sunrise and before sundown to protect the eyes from harmful ultraviolet (UV) rays and bright sunlight that can impair vision while driving. This is particularly important in the context of operating vehicles, including buses. The use of shaded lenses helps enhance visibility and comfort by reducing glare from the sun, which can be particularly problematic during peak sunlight hours. Wearing shaded lenses during this time ensures that drivers can maintain a clear line of sight and react appropriately to their surroundings, enhancing safety for both the driver and passengers. Proper eye protection is a key aspect of traffic safety awareness, which is why it's mandated during these hours.
