Goodwill is a nonprofit organization that operates thrift stores to support various charitable initiatives. While Goodwill accepts a wide range of items, including clothing, furniture, and household goods, their acceptance policy can vary by location. Therefore, it's best to contact your local Goodwill store directly to inquire about their specific guidelines regarding motorcycle helmets. They will be able to provide you with the most accurate information on whether or not they accept motorcycle helmets as donations.
