Massachusetts off-road-vehicle law significantly reduces injuries, hospitalisations in children

The 2010 Massachusetts law restricting the use of off-road vehicles (ORVs) to those age 14 and older led to significant reductions in both emergency department (ED) visits and hospital admissions resulting from ORV injuries in the following three years.

A study by investigators at Massachusetts General Hospital (MGH), comparing injury rates before and after the law's enactment, has been released online prior to publication in the October issue of Pediatrics.

"No other legislation to date has restrictions as tight as those in Massachusetts," says lead and corresponding author Michael Flaherty, DO, of the Division of Pediatric Critical Care Medicine at MassGeneral Hospital for Children (MGHfC). "Most other laws have focused on education, training, helmet requirements and prohibiting ORV riding on public lands. This is the first law of its kind, which makes our results particularly important for the design of future legislation."

The investigators note that, over the past three decades, there have been more than 3,000 ORV-related pediatric fatalities in the US - half in 12- to 15-year olds. Between 2001 and 2010, there were more than 350,000 emergency department visits for those under 15.

Enacted in 2010,"Sean's Law" - named for Sean Kearney, an 8-year-old who died after an ORV he was riding overturned on him -- banned ORV operation by anyone under the age of 14 on public or private land.

Previously children as young as 10 could operate an ORV under certain circumstances. Under the new law, the only exception to the 14-and-older rule was under the direct supervision of an adult on a parent's land in preparation for or while participating in an approved event.

In addition to requiring education and training classes, along with adult supervision, for those 14 to 17, the law also limited the ORVs they could operate to those with engines of 90 cc or smaller. Existing regulations requiring helmet use and outlawing operating under the influence were maintained, and penalties for parents allowing underage children to operate ORVs were increased.

For their comparison of ORV-related pediatric ED visits and hospital admissions for the nine years before and three years after enactment of Sean's law, the investigators analyzed data covering four age categories - ages 9 and under, 10 to 13, 14 to 17, and for purposes of comparison, adults ages 25 to 34. Data reflecting rates of ORV-related ED visits and hospital admissions per total population of each age group were provided by the Massachusetts Department of Public Health.

Even among those ages 9 and under, who would have been prohibited from operating an ORV before the law's implementation, the rate of ORV-related ED visits dropped by 33 percent after 2010. Among those 10 to 13, ED visits dropped 50 percent, and for those 14 to 17, the decrease was 39 per cent.

During the same time period there was no significant change in ORV-related ED visits for the comparison group of 25- to 34-year olds. The rate of hospitalisations for all those 17 and under dropped 41 percent after the law's implementation, while the 25-to-34-year comparison group had a drop of 26 per cent.

Senior author Peter Masiakos, MS. MD, MGHfC Department of Pediatric Surgery, says, "For over 20 years, medical and surgical organizations -- including the American Academy of Pediatrics, American Association of Orthopedic Surgeons and the American College of Surgeons - have been calling attention to the grave risks of ATV riding for children and have urged state and federal governments to take more aggressive action to curb the avoidable deaths and injuries associated with ATV crashes. The results of our study indicate that comprehensive laws that include age restrictions can in fact decrease the numbers of pediatric injuries that result from ATV crashes."

Flaherty cautions, "While our results suggest that age restrictions can work, 14- to 17-year-old riders still have the highest age-based rate of ORV injuries in Massachusetts. Professional societies, including the American Academy of Pediatrics, still recommend restricting ORV use to those 16 and older. We have more room to go in strengthening our state law. Our results suggest the tighter age restrictions may be even more beneficial."
