IIHS Crash Tests Saved 48,352 Lives and $538 Billion Since 1995

The Insurance Institute for Highway Safety credited its crash tests with saving 48,352 lives and $538 billion in societal costs on June 24, 2026, capping 30 years of the testing program that rewrote how vehicles are built. Auto insurers funded that research with roughly $600 million over the same period, a return of nearly 900 times that traces back to the injury claims safer vehicles never produced.

How IIHS Counted the Lives Saved

IIHS researchers measured the gap between vehicles rated good and those rated acceptable, marginal, or poor across five crashworthiness tests, then calculated the deaths that would have occurred had the share of good-rated vehicles never climbed. That math produced 48,352 lives saved between 1999 and 2024, according to the study led by IIHS statistician Amy Schumacher. Schumacher's team valued each life using the U.S. Department of Transportation's value of a statistical life, the figure regulators apply when they weigh a safety rule against the deaths it prevents.

That valuation leaves out medical bills, lost wages, and property damage, so the real economic impact runs higher than the headline $538 billion. Set against the $600 million that member insurers paid IIHS over those years, the testing program returned close to 900 times its cost.

"It feels strange to talk about the monetary value of a person's life, even to researchers," said Amy Schumacher, IIHS statistician and lead author. "But it's a useful way to weigh the cost-effectiveness of different interventions."

Crash Test	Lives Saved (1999-2024)	Introduced	Share of Total
Front (moderate + small overlap)	28,697	1995-2017	59%
Side impact	18,224	2003	38%
Roof strength	1,432	2009-2022	3%

Estimates compare real-world fatality rates of good-rated vehicles against acceptable, marginal, and poor ones across five tests, covering 1999 to 2024. The dollar value uses the U.S. DOT value of a statistical life and excludes medical bills and lost wages.

A 1996 Blazer Meets Its 2026 Twin

To dramatize three decades of progress, IIHS crashed a 1996 Chevrolet Blazer into a 2026 Blazer at just under 40 mph each in a head-to-head version of its moderate overlap front test. The 2026 model's cabin stayed intact, and every injury reading on the crash dummy landed in the minimal-risk range except a slightly elevated number for the right lower leg. Inside the 1996 Blazer, the occupant compartment collapsed, driving the dashboard and steering column into the dummy's lap as the airbag struck its chin.

That 1996 Blazer had earned a poor rating in IIHS testing, a grade that covers models built from 1995 to 2004. Chevrolet rebuilt the Blazer in 2019, and current versions earn good ratings. The last time IIHS staged a demonstration like this, a 1959 Chevrolet Bel Air crumpled against a 2009 Malibu, killing the myth that older cars were built like tanks.

What This Means for Your Insurance

IIHS exists because crashes cost insurers money, and 48,352 fewer deaths line up with millions of injury claims that were never filed. The Highway Loss Data Institute, the IIHS sister organization, collects loss data from carriers writing more than 85% of U.S. private-passenger policies, then publishes injury and collision results by make and model. Insurers read those tables when they price a vehicle, which is why two similar SUVs can carry very different premiums.

HLDI data found that bundling modern crash-avoidance features cut some property-damage claims by up to 39%, with rear automatic emergency braking ranking as the single most effective feature. The vehicle you drive also sits among the rating factors carriers use to set your premium, alongside your ZIP code, driving record, and credit. A model that fails a crash test can cost its owners more, as Jeep Wrangler drivers learned before the 2026 redesign fixed the problem.

GEICO's restraint-device discount trims up to 23% off the medical-payments or personal-injury-protection portion of a policy for cars with airbags and passive restraints, though it applies only to those medical coverages and varies by state. Stacking safety, anti-theft, and bundling discounts can cut a full premium by up to 40% at major carriers.

Why Insurers Pay for the Crash Tests

IIHS Chief Operating Officer Joe Nolan tied the 48,352 saved lives straight back to the insurers who pay for the research.

Few vehicles aced these tests when IIHS rolled them out, yet nearly every new model earned a good rating before each evaluation was retired or toughened. The moderate overlap front test debuted in 1995 and added back-seat protection in 2022. IIHS combined its driver- and passenger-side small overlap tests into one rating in 2024 and retired the roof-strength evaluation in 2022 after federal rules matched its standard.

What You Should Do Now

What Comes Next

IIHS keeps raising the bar, so a good rating in 2026 reflects a far tougher test than a 2015 model passed. The institute added a tougher whiplash test in 2026 and now scores crash avoidance and headlights on top of the original crashworthiness battery, leaving only 63 vehicles with a Top Safety Pick or Top Safety Pick+ award this year. Anyone shopping a used car should match the model year against the rating, because a Blazer built in 2003 and one built in 2026 share a name and almost nothing about their crash results.
