A jury ruled that the design of a sport utility vehicle made by Isuzu Motors Ltd. did not cause the death of a teenager killed in a rollover crash.

Jeremy Bass, 16, was on a field trip with several classmates when the 1992 Rodeo he was driving flipped over after he swerved to avoid a stopped car in the November 1993 accident.His mother, Judith Cartrette, sued for $7 million, saying that the Rodeo was prone to roll when making turns at high speeds, the doors could open and the seat belts could unfasten in an accident.

The jury decided Friday that a combination of speed, inexperience and lack of a safety belt led to the death.

Cartrette's attorneys said she will appeal.
