Page 22 - The studies evaluated showed that most motorcycle riders wore helmets in those states with universal helmet laws. In states with no law or limited laws, roughly half of all the riders wore helmets. Studies of the impact of helmet laws showed substantially lower fatality rates when universal laws were in effect, with most of the results falling in a range of 20 to 40 percent lower.

Page 17 - Although the studies evaluated differed in the specific questions addressed and the methodologies used, they were consistent in pointing to a safety benefit from helmet use. The studies that compared helmeted with nonhelmeted accident victims all found that helmeted riders had lower fatality rates. Rates ranged from 28 to 73 percent lower, depending on how researchers defined their study population. Studies that addressed injury severity showed that surviving helmeted...

Page 3 - GAO reported that when universal helmet laws have been in effect, fatality rates have generally been 20 to 40 percent lower than during periods before enactment or after repeal.
Page 59 - Severe injuries increased from 8.1 to 11 percent of involved riders, serious injuries from 2.3 to 3.7 percent, nonfatal critical injuries from 0.4 to 1.9 percent, and fatalities from 1.4 to 2.3 percent. Among injured riders, injury severity increased significantly after the helmet law was repealed. Fatalities increased from 2.6 percent in 1976 to 3.7 percent in 1977 and 4.9 percent in 1978. Severe injuries increased from 14.3 percent in 1976 to 17.8 percent in...
Page 2 - In 1990, over 3,000 motorcycle riders were killed in traffic accidents in the United States. The National Highway Traffic Safety Administration (NHTSA) has reported that about 55 percent were not wearing protective helmets.

Principal Findings What levels of helmet use are associated with universal helmet laws and limited helmet laws? The observational surveys found helmet use after reenactment ranging from 90 percent in New Orleans to 100 percent in Baton Rouge. Overall, 96 percent of the 1,465 riders observed were wearing helmets.
