IIHS Announces New Whiplash Prevention Test
New IIHS Whiplash Test Shows Many Small SUVs Still Fall Short
Rear-end crashes are a fact of life in the Washington, D.C. region. Stop-and-go commutes, sudden braking, and tight following distances create the exact conditions where neck injuries happen most often. That is why a new safety update from the Insurance Institute for Highway Safety matters for everyday drivers, not just safety engineers, and why it is also on the radar for a Maryland car accident lawyer handling rear-end collision claims tied to whiplash and other neck injuries.
The Insurance Institute for Highway Safety has launched a new seat and head restraint evaluation focused on neck sprains and strains. Those injuries are not rare outliers. IIHS President David Harkey noted that neck sprains and strains are the most frequently reported injuries in U.S. auto insurance claims, and the new test is designed to push automakers to do better in the kinds of rear impacts that cause them.
What IIHS Changed And Why It Matters
IIHS used to run a different head restraint evaluation, but it stopped that test in 2022 because automakers had improved designs to the point where nearly every vehicle earned a good rating. That progress helped, but it did not solve the real-world problem. Insurance data still showed meaningful differences in whiplash claim rates across models, even when the older test could not separate the best designs from the merely adequate ones.
To build a better test, IIHS tested seats from 36 late-model vehicles at three impact speeds, then looked for correlations between the dummy measurements and higher injury claim rates using insurance data supplied by the IIHS-affiliated Highway Loss Data Institute. The resulting evaluation uses two separate acceleration pulses to simulate rear impacts at 20 mph and 30 mph.
That change matters because many rear-end crashes occur at speeds that don't look dramatic on a police report but still cause a sharp, whipping motion in the neck. Rear-end crashes are also extremely common nationwide. A National Highway Traffic Safety Administration (NHTSA) vehicle safety research note has estimated that they account for more than 29% of all crashes.
How 18 Popular Small SUVs Performed
The first round of whiplash test results focused on 18 small SUVs, mostly model-year 2025, with one 2024–25 model included. Many ratings extend into the 2026 model year. Only four earned a good rating.
Before the list, one point is worth noting. This evaluation is narrowly focused on rear-impact neck injury prevention. A vehicle can perform well in many other crash categories and still lag here, which is exactly why IIHS created a more discriminating test.
- Good: Audi Q3; Hyundai Ioniq 5; Subaru Forester; Toyota RAV4.
- Acceptable: Buick Encore GX; Chevrolet Equinox; Honda CR-V; Jeep Compass; Kia Sportage; Mercedes-Benz GLB-Class; Mitsubishi Outlander; Volkswagen Taos; Volvo XC40.
- Marginal: BMW X1; Nissan Rogue.
- Poor: Ford Bronco Sport; Hyundai Tucson; Mazda CX-50.
For drivers and families, the practical takeaway is simple. Seats and head restraints still vary a lot across vehicles that otherwise look similar on paper. This new rating makes those differences harder to ignore.
Why Whiplash Claims Get Minimized So Often
Whiplash is frequently framed as a minor “soft tissue” injury, but it can derail daily life. Neck pain can limit sleep, work, childcare, exercise, and the ability to drive without discomfort. Symptoms also do not always appear immediately after a crash. Medical resources commonly note that whiplash symptoms can develop over time after the incident rather than all at once at the scene.
That delay is one reason insurers may argue that a person is “fine” because they walked away, declined an ambulance, or finished the drive home. Another reason is that rear-end crashes sometimes involve modest visible vehicle damage, even when the vehicle's body experienced a sharp acceleration change.
The new IIHS test is a reminder that injury risk is closely tied to seat and restraint design, not just the size of the dent in a bumper.
Practical Steps That Can Reduce Neck Injury Risk
Modern vehicle safety is not only about airbags. Basic seat setup still matters.
- Head Restraint Height: Set the restraint high enough that the top aligns near the top of the head, placing the thickest part behind the head around ear level.
- Head Restraint Distance: Keep the gap between the head and the restraint as small as comfort allows, since larger gaps allow more head travel before contact.
- Upright Seating: Avoid reclining too far, as posture affects how the head and neck move during a rear impact.
These steps do not “prevent” all whiplash injuries, but they can reduce how violently the head snaps in the first critical fraction of a second.
Timing Matters In DC, Maryland, And Virginia Injury Claims
Rear-end crash injury claims often become a fight over records, timelines, and credibility. That is where early documentation tends to matter, especially in jurisdictions where insurers look for any alleged mistake to deny payment.
Deadlines also matter. General personal injury limitation periods in the region commonly include three years in the District of Columbia, three years in Maryland, and two years in Virginia. However, exceptions can apply depending on the facts.
