Oklahoma teens' car reportedly made "rolling stop" before crash that killed 6, NTSB says

A small four-seat car carrying six Oklahoma teenagers reportedly failed to come to a full stop before entering an intersection where it was hit by a large truck, killing all of the teens, the National Transportation Safety Board said Thursday.

"Witnesses reported the (vehicle) made a 'rolling stop' at the stop sign and entered (the intersection)," where it was struck Tuesday by a truck that was hauling rocks, according to a statement from NTSB spokesperson Peter Knudson.

The southbound semitrailer struck the left front of the eastbound vehicle carrying the girls and both vehicles departed the roadway, according to the NTSB.
