How is liability determined in a high-speed rear-end collision?

[ElliotAnn]

High-speed rear-end collision liability is determined as follows: 1. If the rear vehicle collides with the front vehicle in motion, the rear vehicle bears full responsibility; 2. If the front vehicle lacks taillights at night, the front vehicle bears secondary responsibility while the rear vehicle bears primary responsibility; 3. If the front vehicle stops on the road without activating hazard warning lights or setting up warning signs as required, the front vehicle bears secondary responsibility while the rear vehicle bears primary responsibility; 4. If the front vehicle stops on the road with properly activated hazard warning lights and warning signs, the rear vehicle bears full responsibility. The Road Traffic Safety Law of the People's Republic of China stipulates: When a motor vehicle breaks down or is involved in an accident on the road, obstructing traffic and being difficult to move, hazard warning lights must be activated and warning signs set up 50 to 100 meters behind the vehicle, with position lights and rear lights also turned on at night.
