How to distinguish responsibility when a car is rear-ended by a motorcycle?

If the car has no other illegal acts, the motorcycle is fully responsible. Judging from your problem, the rear-end chaser is fully responsible. However, there are exceptions to rear-end collision, for example, the lane change of the front car is not completed (the body is still riding the marking line), which is the main responsibility of the front car.

Then if the driver in front of the vehicle is involved in driving under the influence of drugs, drunk driving, driving without a license and other laws to severely crack down on and prohibit driving, it will also lead the driver in front of the vehicle to bear certain responsibilities.

Spiritual compensation, no legal responsibility.

If the driver's license provided is true and legal, and there is no illegal behavior while driving, a warning or a fine of 20-200 yuan will be given, and the motor vehicle will be returned in time.

The driver's license provided is true and legal, but if there is any illegal act while driving, it will be punished according to the illegal situation and the driver's license that is not carried with you, and the motor vehicle will be returned in time.
