What should riders do to make it easier for others to recognize them?

Wearing bright colors and reflective materials significantly enhances a rider's visibility to other road users. These types of clothing or gear reflect light, especially in low-light conditions or at night, making it much easier for drivers and pedestrians to notice the rider from a distance. Bright colors stand out against many backgrounds, which is crucial for safety on the road.

In contrast, while riding slowly in crowded areas can be helpful for the safety of the rider and others, it does not necessarily improve visibility. Using a loud horn can alert nearby vehicles or pedestrians but does not make the rider more visible; rather, it only serves as an auditory warning. Staying in the left lane may not be relevant to visibility and might not even be an option in many situations, as lane choice should be determined by traffic conditions and regulations rather than solely for visibility purposes. Therefore, utilizing bright colors and reflective materials is the most effective strategy for increasing a rider's visibility and recognition on the road.
