Tulsa Police believe the driver of a Ford Taurus ran a red light when the car was hit by an eastbound propane delivery truck at 15th and Yale Thursday morning.
The impact caused the northbound Taurus to hit a Honda and a Dodge Durango waiting to go north at about 8:30 a.m.
EMSA took three people to the hospital after the four vehicle crash. Officers said all three appeared to have suffered non-life threatening injuries.
The collision blocked the intersection for about an hour while police investigated.
