Cover of Motorcycle Helmet Effectiveness Revisited -- Technical Report

Cover illustration of an aerial view of a motorcycle skidding in the middle of the road

Six captions on the right side of the illustration starting from the bottom:

• Rear brake locks – Skid starts (59 foot skid mark)
• Rear end moves to right – Steering correction begins “into” skid
• Steering reaches “stop” – Skid now cannot be compensated for
• HIGHSIDE – Both motorcycle and rider fly through the air
• Rider hits ground after flying over motorcycle which is still in the air – Rider begins immediate rolling action
• Rider comes to rest – Unconscious

Four captions on the left side of the illustration starting from the bottom:

• Motorcycle hits ground on right side after flight
• Second bounce – Motorcycle upside down – Misses rider who is still rolling
• Third bounce – Left side
• Motorcycle flips – Stops ONE FOOT short of rider

Underneath the illustration are three logos. From left to right, they are: U.S. Department of Transportation National Highway Traffic Safety Administration logo, NCSA National Center for Statistics & Analysis of the National Highway Traffic Safety Administration logo, and NHTSA People Saving People, www.nhtsa.dot.gov logo
