Electronic stability control technology (ESC) is saving an increasing number of lives each year, according to a three-year study by the U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA). The NHTSA study estimates that ESC saved 2,202 lives from 2008 to 2010 alone. Electronic stability control was mandated on all light-duty trucks and passenger vehicles under a federal safety regulation issued in 2007. The requirement was phased in over the years covered by the study and applies to all new light vehicles manufactured on or after Sept. 1, 2011.
