Motorcycle and electric vehicle traffic accident how to handle

   At noon yesterday 12:00 work colleagues, riding a motorcycle home, go to a north-south road accident. This is how the story goes:

   My friends riding a motorcycle in the north and South Road along the lane on the right side go north, the other riding electric cars in the non motor vehicle lanes retrograde South right away, please note that the middle lane and non motor Lane isolation belt, the isolation belt growers of flowers and trees, at intervals of about 50 meters, there is a gap between the isolation belt. On the a gap, electric vehicles from the non motorized road turns into the driveway, and the normal running of the motorcycle collided. Accidents caused by my friend, is also riding a motorcycle, the motorcycle front fell down, causing head and facial trauma; and the other, is riding the electric car, causing a fracture of the leg on the spot. The following is the accident diagram:

Obviously, is the electric vehicles peccancy. But I heard the traffic law, motor vehicle and non motor vehicle traffic accidents, no matter what the situation, the vehicle must undertake certain responsibility. In cases like this, how the traffic police team will delineate the responsibilities? The medical expenses will be borne.
