Car safety ratings evaluate a vehicle’s crash protection and accident avoidance capabilities through standardized tests. Organizations like the NHTSA (5-star scale) and IIHS (Top Safety Pick+) assess factors like crashworthiness, pedestrian detection, and rollover resistance. High ratings indicate advanced safety tech (e.g., automatic emergency braking) and structural integrity. These ratings guide consumers toward vehicles with proven protective features, reducing injury risks by up to 50% in severe collisions.

Who sets car safety ratings?
Primary agencies include the NHTSA (U.S. government) and IIHS (non-profit). NHTSA uses frontal/side crash tests and rollover resistance metrics, while IIHS evaluates crash avoidance tech and roof strength. Both assign ratings via star systems or awards like Top Safety Pick+.
NHTSA’s New Car Assessment Program (NCAP) tests vehicles at 35 mph for frontal crashes and 38.5 mph for side impacts. IIHS, however, conducts tougher moderate overlap front tests at 40 mph. Pro Tip: Always cross-check NHTSA and IIHS ratings—a 5-star NHTSA car might lack IIHS’s Top Safety Pick+ due to poor headlight performance. For example, the 2023 Honda Accord earned 5 stars from NHTSA but missed IIHS’s highest award because of marginal child seat anchor usability.
How are safety ratings tested?
Ratings derive from crash simulations, avoidance tech trials, and structural analyses. NHTSA conducts frontal, side, and rollover tests, while IIHS adds roof strength and pedestrian detection evaluations. Sensors measure dummy injury risks, and vehicles must maintain survival space.
Beyond basic crash tests, IIHS uses a 25% small overlap front test mimicking collisions with poles or trees. This test stresses a car’s ability to redirect crash energy away from occupants. Pro Tip: Prioritize vehicles with Good ratings in IIHS’s driver-side small overlap test—it’s 20% deadlier than moderate overlaps. For instance, the Subaru Outback aced this test due to its reinforced floor structure, while some trucks scored Poor. Why does roof strength matter? Strong roofs reduce crush intrusion during rollovers, which account for 30% of crash deaths.
| Test Type | Speed | Key Metric |
|---|---|---|
| Frontal (NHTSA) | 35 mph | Head/chest injury risk |
| Side (IIHS) | 31 mph | Pelvis/thorax forces |
| Small Overlap (IIHS) | 40 mph | Footwell integrity |
Why are safety ratings important for buyers?
High ratings correlate with 40–50% lower fatality risks in severe crashes. They also influence insurance premiums and resale value. Vehicles with Top Safety Pick+ often cost 3–5% less to insure annually compared to poorly rated models.
In practical terms, a 5-star NHTSA-rated SUV reduces spinal injury risks by 37% in rollovers versus a 3-star counterpart. Pro Tip: Focus on vehicles with advanced driver-assistance systems (ADAS)—they cut rear-end collisions by 50%. For example, the Toyota RAV4’s automatic braking helped it secure a 2023 Top Safety Pick+, whereas the Nissan Kicks lost points for lacking pedestrian detection. But what if your budget is tight? Opt for older Top Safety Pick winners—they still outperform non-rated models.

FAQs
Not always—models like the Mazda CX-5 offer top safety ratings at mid-range prices. However, advanced ADAS tech can add $1,500–$3,000.
Can a 10-year-old car have updated safety ratings?
No, ratings apply only to the tested model year. Retroactive updates don’t occur, though older Top Safety Picks remain safer than unrated vehicles.
Do safety ratings affect insurance?
Yes, many insurers offer 5–15% discounts for IIHS Top Safety Pick+ models due to lower claim frequencies.
