The division basis of traffic accident responsibility is mainly as follows:
1. Whether the party violates the regulations
2. Whether there is a causal relationship between violations and accidents
3. What is the role of violations in the accident.
If there is a violation, and there is a causal relationship between the behavior and the accident, then the accident liability should be assessed according to the role of the violation in the accident. Accident liability is divided into full liability, primary liability, equal liability and secondary liability.
