In case of accidents caused by driving other people's cars, the case can be considered as follows: 1. If the main body responsible for the traffic accident is the direct responsible person, the owner shall assume supplementary responsibility under corresponding circumstances. 2. If the borrower has the driving qualification, the owner is not at fault, and the borrower shall bear the responsibility. 3. If it is lent to a person without driving qualification to drive, the owner himself has illegal and fault liability and should bear the corresponding legal consequences. What needs to be clear is that if someone else's car is involved in an accident, the owner should also be responsible for the relevant incident.
