The National Highway Traffic Safety Administration has given five-star ratings to five minivan models, indicating that passengers have a serious injury risk of ten percent or less in frontal and side-impact collisions at 35 miles per hour.

Chrysler's Town & Country, the Grand Caravan by Dodge, Kia's Sedona, Mazda's MPV and the Nissan Quest scored best among 32 models tested.

The Chevrolet Astro van and the GMC Safari received the lowest three-star ratings.

The chance of serious injury in a real-world crash was between 21 and 35 percent.

Ford's E-150 was the only one of 13 minivans to tip over in rollover test.

NHTSA's analysts say it has nearly a 30 percent chance of rolling over.
