Start your engines! Summer is here, and the longer, warmer days bring plenty of opportunity for off-road recreational vehicles. As the popularity of off-highway vehicles (OHVs) has risen to an all-time high, so too have deaths and injuries. Despite warnings from manufacturers, federal agencies, and consumer and safety advocates that OHVs (often referred to as ATVs) are unsafe on roadways, they’re showing up there more often, partly because of relaxed state and local laws. The result? About 65% of fatal OHV crashes occur on public or private roads. Before you strap on a helmet and turn the key, you should know the risks associated with these powerful vehicles.
