What feature of an approved helmet helps the wearer while riding?

The correct feature of an approved helmet that benefits the wearer while riding is its design that allows for adequate peripheral vision. This is essential for safe riding since motorcyclists must constantly scan their surroundings for potential hazards, other vehicles, pedestrians, and changes in road conditions. An approved helmet is constructed to provide the necessary visibility without compromising safety, allowing riders to look to the side and maintain awareness of what's happening around them.

While other features like audio awareness or decreased wind resistance might seem relevant, they do not directly address the critical aspect of visual awareness that is crucial for a motorcyclist's safety. Enhancing night vision is not a property of conventional helmets, and their primary function focuses on protection and ensuring that the rider can have a broad field of vision.
