What is the minimum visibility distance for the front lamp on a bicycle?

The minimum visibility distance for the front lamp on a bicycle is specified as 500 feet. This requirement is intended to ensure that cyclists can be seen by motorists from a significant distance, enhancing safety on the road, especially in low-light conditions. A front lamp with a visibility range of 500 feet allows drivers approaching from behind or the opposite direction to detect the presence of a cyclist well in advance, which is crucial for preventing accidents.

Other options suggest shorter visibility distances, which, while better than having no light at all, would not provide the same level of safety. Adequate visibility is essential for both the cyclist's safety and the awareness of drivers, making the 500-foot requirement particularly important in promoting a safer biking environment.
