Memorial Day weekend is among the deadliest times for all-terrain vehicle riders, with 27 fatalities recorded over the holiday last year, the U.S. Consumer Product Safety Commission warns.

ATV-related deaths from March to April spike an average of 30 percent for children younger than 16 and 88 percent for adults, according to the CPSC. From 2003 to 2005, ATV-related deaths climbed each month during the spring and into the summer, peaking in July, when an average of 23 children and 87 adults were killed.

More than 10,000 people have died in ATV crashes since the 1980s, FairWarning reported in March. More than 2,500 deaths and hundreds of thousands of injuries involved kids under 16.
