"ARLINGTON, VA — More states are allowing a relatively new breed of vehicle on public roads, but crash tests by the Insurance Institute for Highway Safety show why the mix of low-speed vehicles (LSVs) or minitrucks and regular traffic is a deadly combination. LSVs are designed for tooling around residential neighborhoods, and minitrucks are for hauling cargo off-road. While these vehicles have a lot of appeal as a way to reduce emissions and cut fuel use, they don't have to meet the basic safety standards that cars and pickups do, and they aren't designed to protect their occupants in crashes.
"By allowing LSVs and minitrucks on more and more kinds of roads, states are carving out exceptions to 40 years of auto safety regulations that save lives," says David Zuby, the Institute's chief research officer. "It's a troubling trend that flies in the face of the work insurers, automakers, and the federal government have done to reduce crash risk."
Practically every state allows LSVs, also called neighborhood electric vehicles, on certain roads, mostly with 35 mph or lower speed limits. Eight years ago just over a dozen states permitted them. Now 46 do. The National Highway Traffic Safety Administration (NHTSA) defines appropriate performance and safety standards but has no say in where LSVs are driven. The same goes for minitrucks, which are legal to operate on some roads in 16 states, even though they weren't designed to meet US safety or emission standards. The trend to grant minitrucks access to regular roads began in 2007 and is growing at a quick pace."
