A car accident earlier tonight on the Kennedy Expressway left three motorcyclists and another person injured. This car accident occurred in downtown Chicago and seems to have been a chain reaction in which three motorcycles struck each other and then one hit a car. Luckily traffic was moving slowly and all the motorcyclists were wearing helmets so no one was fatally injured. All of the motorcycle drivers as well as the driver of the car involved in the car accident were taken to local hospitals for treatment of their personal injuries.
