• Abstract:
  This report evaluates the effectiveness of electronic stability control (ESC) in mitigating single-vehicle, first-event rollover crashes. NHTSA mandated ESC standard equipment in certain light vehicles manufactured on or after September 1, 2011, by Federal Motor Vehicle Safety Standard (FMVSS) No.126, Electronic stability control systems. The study used National Automotive Sampling System (NASS) General Estimate System (GES) data from 2013 to 2015 to compare outcomes for similar vehicles with and without ESC. This research estimated a logistic regression model that found that a vehicle with ESC is 51.6 percent less likely on average to be in a single-vehicle, first-event rollover crash than a vehicle without ESC if all other variables remain fixed. Considering effectiveness, we saw an overall first-event, single-vehicle rollover crash relative risk reduction of 47.7 percent on the grouping of vehicles with ESC and vehicles without ESC, accounting for the effect of passenger vehicle body type and travel speed. The reduction is statistically significant at alpha level 0.05. These conclusions align with prior evaluations of ESC that found a reduction in first-event rollover crashes due to the technology.
