Preliminary reports indicate that one of the vehicles overturned after a Mazda and a Honda Accord traveling on I-95 North collided near I-895 by the Baltimore-Howard County line, said Sergeant Anthony Riley of the Maryland State Police.

The driver and passenger of the Accord were transported by ground to shock trauma for injuries, said Riley. The driver of the Mazda was not injured, reported police.

The cause of the incident is unknown at this time, said Riley, who noted that officials are still investigating.
