The August 10, 2011 Federal Register contained NHTSA’s updated statistical analysis on its existing Safety Standard 126, Electronic Stability Control Systems. The report’s title is: Crash Prevention Effectiveness in Light-Vehicle Electronic Stability Control: An Update of the 2007 NHTSA Evaluation.  The Notice stated:

“Statistical analyses based on data for calendar years 1997 to 2009 from the Fatality Analysis Reporting System (FARS) and the General Estimates System (GES) of the National Automotive Sampling System (NASS) estimate the long-term effectiveness of electronic stability control (ESC) for passenger cars and LTVs (light trucks and vans). Safety Standard 126 establishes standards for electronic stability control systems manufactured for use in light vehicles. This report is an update of a previous NHTSA analysis of ESC effectiveness (72 FR 41582) published in 2007.”

“The principal findings are that ESC was associated with a six percent decrease in the likelihood that a vehicle would be involved in any police reported crash and an 18 percent reduction in the probability that a vehicle would be involved in a fatal crash. For passenger cars, the reductions are 5 percent and 23 percent, respectively; for LTVs, 7 percent and 20 percent. Each of these reductions is statistically significant except for the 5 percent overall effect in cars.”
