[Ground of recognition] Facts without dispute, Gap evidence Nos. 1 through 5, Gap evidence No. 1 and the purport of the whole pleadings

2. According to the facts of the above recognition and each of the above evidence, it is reasonable to view that the accident in this case was caused by the principal mistake of the driver of the Defendant vehicle driving in the central line.

However, in a case where the Plaintiff’s driver, who is also a driver of the instant parking lot, honded by a bend, closely displayed the front door while driving the instant parking lot, it appears that the occurrence of the instant accident or the expansion of damage could have been avoided. In light of the developments leading up to the occurrence of the instant accident, the width and shape of the passage of the instant parking lot, and the degree and degree of the damage to each of the instant vehicles, it is reasonable to view that the fault ratio of the Plaintiff’s driver and the Defendant’s driver is 10:90.

Therefore, the Defendant, who is the insurer of the Plaintiff’s vehicle, insurance money for KRW 966,60,60 (=1,074,000 x 90%) and KRW 751,800, which is the amount cited in the judgment of the first instance court, out of the insurance money paid by the Plaintiff due to the instant accident.
