Changes in Crash Protection With Vehicle Model Year

NASS 1993-2015 was queried for frequency of exposed vehicles with belted driver injuries separated by injury severity and vehicle model year. Vehicle model-years were aggregated by 3 model year groupings – 1985 -1994; 1995-2000; 2001-2015. These percentages of the crash exposed populations for the 3 groups were: 27%, 34% and 39%. The total exposed population was 27,347,705. The total and Mean AIS 3+ HARM for each model year grouping was calculated for each crash mode – frontal, near-side, far-side, rear and rollover. Changes in total AIS 3+ HARM distribution and Mean AIS 3+ HARM by crash mode and model year grouping were reported. The largest source of AIS 3+ HARM to belted drivers in the 2001-2015 NASS population remains the frontal crash mode. Near-side and rollover injury rates have dramatically decreased in recent model years. Frontal and far-side crash mode injury rates have decreased slightly and rear has remained relatively constant, but at a low injury rate. The data suggests that for light trucks, the near-side Mean AIS 3+ HARM has increased during the 2001-2015 model years. However, the level remains below that of passenger cars which have experienced dramatic reductions in near-side Mean AIS 3+ HARM during the same period.
