Child Safety Seat
The agency was careful to note that it did not evaluate crash protection, but rather only proper belt position, crucial for proper child protection. Standard three-point seatbelts are designed for adult-sized frames, making it easy for children to slide beneath belts, get pinned in soft and vulnerable areas during a crash, or become entangled in the belts (rather than restrained) during rapid deceleration.
Some vehicles, like safety-oriented Volvos, offer integrated booster seats as a factory option on vehicles like the V70 Wagon. Integrated booster seats were not covered in the IIHS' test.
IIHS did give its seal of approval to 15 booster seats, with 10 receiving the organization's "best bet" rating, and five earning a "good bet" stamp of approval.
