Helmet use is associated with a decrease in intracranial hemorrhage following all-terrain vehicle crashes.

Background: With the recent increase in size and horsepower of all-terrain vehicles (ATVs), it is imperative that preventable injuries be identified to protect the large population using ATVs. Currently, many states have no laws regulating ATV or helmet use. By identifying preventable injuries, the legislature can design appropriate laws to protect both children and adults.
