Which of the following is a safety feature recommended for motorcycle riders?

Wearing a reflective vest is a highly recommended safety feature for motorcycle riders because it significantly enhances visibility. Motorcycles can sometimes be less noticeable on the road compared to larger vehicles, especially in low-light conditions or adverse weather. A reflective vest reflects light from headlights and streetlights, making the rider more visible to other motorists. This is essential for preventing accidents and ensuring the safety of the rider.

The other choices, while they represent different approaches to riding, either lack protective qualities or actively compromise safety. Wearing jeans and sneakers does not provide adequate protection in the event of a fall. Using headphones while riding can distract from hearing important sounds on the road, such as sirens or honking horns, and cycling without any protective gear completely disregards the necessary safety equipment that can mitigate injuries in an accident.
