2018 Kia K900 crash-test ratings

NHTSA 5-Star Safety Ratings for the tested versions. More stars mean a lower chance of serious injury in that type of crash. Rollover risk is NHTSA's estimated chance of rolling over in a single-vehicle crash.

Tested vehicle	Overall	Frontal	Side	Rollover	Rollover risk	Forward collision warning
