Evaluation of FMVSS No. 301, Fuel System Integrity, as Upgraded in 2005 to 2009

National Highway Traffic Safety Administration (NHTSA) issued a final rule to upgrade Federal Motor Vehicle Safety Standard (FMVSS) No. 301, Fuel System Integrity, on December 1, 2003, to amend the prior standards in rear and side impacts. By increasing the impact speeds and using a moving deformable barrier, the amended test conditions are more comparable with real-world crashes than the prior standards. The rear impact upgrade phased in during model years 2007 to 2009, whereas the new side impact test went into effect in model year 2005. The analysis of the rear impact upgrade shows a statistically significant reduction in post-crash fires ranging from 50 to 60 percent. In addition, the rear impact upgrade would reduce 35 percent of the fatalities caused by rear impact fires. NHTSA believes that the rear impact upgrade will save an estimated 23 lives per year, if all vehicles meet the rear impact upgrade. However, the data do not currently show that the side impact upgrade resulted in a statistically significant reduction in side impact fires. The statistical analysis does not show any significant affiliated effect of the rear impact upgrade on frontal impact fires and first-event-rollover fires. The statistical inference of the rear impact upgrade should not apply to other crash modes.
