IIHS sits in the vehicle-safety evidence lane, not the general car-shopping lane. It is most useful when you need crashworthiness ratings, headlight results, and front crash prevention details tied to specific model years, body styles, and equipment, rather than broad editorial reviews or dealer inventory. For safety-first buyers, fleet screeners, and transport reporters, that narrow scope is the value.
On first use, IIHS is usually clear if you already think in crash-test terms: small overlap, side impact, pedestrian front crash prevention, and headlight performance. The product fits when your real task is comparing safety evidence across candidate vehicles or checking a seller claim. Its boundary matters too: it will not replace pricing, recall lookup, repair cost, or long-term reliability research.
