Approximately 750 persons are injured.
Approximately 30 persons die.
Approximately 82% of persons killed are not wearing helmets.
Approximately 70% of non-helmeted persons die from head injuries, compared to 36% for helmeted persons.
A study of motorcycle crash injuries conducted in Oklahoma in 1994 found helmets were 60-75% effective in reducing moderate, severe and fatal head injuries.
Non-helmeted riders compared to helmeted riders were:
2½-5 times more likely to suffer a fatal head injury.
1½ times more likely to require hospitalization and associated medical costs were higher.
Two times more likely to suffer a nonfatal head injury.
Spinal cord injuries did not differ by helmet status; neck injuries were somewhat lower among helmeted persons vs non-helmeted persons (7% vs 10%, respectively).
Acute hospital charges in 1994 were more than $4.5 million.
Non-helmeted persons accounted for 72% of those costs.
Insurance paid for 40% of medical costs; the majority of the remaining two-thirds was paid by government or left unpaid.
The total societal costs, including medical and emergency costs, productivity losses, insurance expenses, legal and court costs, etc., in 1994 were estimated at $48 million (using 1994 dollars).
The economic savings of a universal motorcycle helmet law in Oklahoma were estimated at more than $6 million a year.
