Slick road conditions were likely the cause of a collision between a motor scooter and a car tonight that has left the motor scooter riders in the hospital, Ann Arbor Police Lt. Angella Abrams said.

Around 8 p.m. tonight, a motor scooter carrying two people and a Dodge Intrepid collided at the intersection of Packard Street and East University, she said.

Two motor scooter passengers, who were wearing helmets at the time of the collision, were injured and are being treated at the University of Michigan Hospital. The injuries are not believed to be life threatening, Abrams said. The driver of the Intrepid was not injured.

“We suspect it was weather-related,” she said. “It was dark out and it had just started raining.”
