How can a rider improve visibility when riding in heavy traffic?

Answer: B — By wearing bright or reflective clothing

Wearing bright or reflective clothing significantly enhances a rider's visibility in heavy traffic conditions. Bright colors, such as fluorescent yellow or orange, stand out against the backdrop of vehicles and road environments, making it easier for other drivers to see the motorcyclist. Reflective materials further increase visibility at night or in low-light conditions by reflecting headlights from surrounding traffic. This practice is crucial in preventing accidents, as it draws attention to the rider and signals their presence to other road users, reducing the risk of collisions. Using hand signals while riding can aid in communication but does not inherently increase visibility to other vehicles. Riding in the center of the lane does help avoid potential hazards like road debris, but it does not enhance visibility in the same way as wearing bright clothing. Installing extra lights on the motorcycle is beneficial for increasing the visibility of the bike itself but may not be as effective as the immediate impact of bright or reflective apparel worn by the rider.
