The design of motor cycle helmets has been changing over the years and at the present time there are two basic types in popular use: "full-face" and "jet" helmets. Both helmet types give good protection to the brain, but, one would think, different degrees of facial protection. A special study of traffic crashes has indicated that full-face helmets provide significantly greater protection against facial injury than do jet helmets. The study also indicated that the wearers of full-face helmets have no greater risk of involvement in road traffic crashes than do the wearers of jet helemts. It is suggested that the use of full-face helmets should be encouraged and consideration given to the revision of helmet standards to require the provision of facial protection.
多年来，摩托车头盔的设计一直在变化，目前流行使用的有两种基本类型：“全脸”头盔和“喷气式”头盔。这两种头盔都能很好地保护大脑，但人们会认为它们对面部的保护程度不同。一项关于交通事故的专项研究表明，全脸头盔在防止面部受伤方面比喷气式头盔提供的保护要大得多。该研究还表明，佩戴全脸头盔的人卷入道路交通事故的风险并不比佩戴喷气式头盔的人高。建议鼓励使用全脸头盔，并考虑修订头盔标准，要求提供面部保护。
