Fatal accidents typically occur when the vehicle rolls over. In the United States, statistics released by the Consumer Product Safety Commission CPSC show that in 2005, there were an estimated 136,700 injuries associated with ATVs treated in US hospital emergency rooms. In 2004, the latest year for which estimates are available, 767 people died in ATV associated incidents. According to statistics released by CPSC, the risk of injury in 2005 was 171. 5 injuries per 10,000 four wheel ATVs in use. The risk of death in 2004 was 1. 1 deaths per 10,000 four wheelers in use. Focus has shifted to machine size balanced with the usage of ATVs categorized by age ranges and engine displacements—in line with the consent decrees. ATVs are mandated to bear a label from the manufacturer stating that the use of machines greater than 90 cc by riders under the age of 12 is prohibited. This is a 'manufacturer/CPSC recommendation' and not necessarily state law. According to The New York Times on September 2, 2007, the Consumer Product Safety Commission met in March 2005 to discuss the dangers of ATVs.
