abstract="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.",
