2. The parties' assertion

A. The Plaintiff’s assertion that the instant accident occurred due to the Defendant’s violation of the duty of safe driving by the driver of the Defendant vehicle, is reasonable to deem that the negligence of the Defendant vehicle is 30%, and thus, the Plaintiff’s claim for the payment of KRW 165,828 (52,760 x 0.3) as the amount of reimbursement.

B. The instant accident alleged by the Defendant is 100% of the negligence of the Plaintiff’s vehicle, since the Plaintiff’s vehicle driven along the road for one-way traffic and left-hand turn at the intersection and the Defendant’s vehicle that entered the road was shocked.

Therefore, the defendant does not have the obligation to pay the indemnity to the plaintiff.

3. Determination

A. According to the above facts of the negligence ratio, the accident in this case was caused by the negligence committed by the Plaintiff’s vehicle driving along the lane on which one-way traffic mark is marked, and by negligence not examining whether the Defendant’s vehicle has a vehicle at the intersection and to turn to the left. However, the driver of the Defendant’s vehicle who normally turn to the left at the intersection is the one-way road in violation of the one-way traffic direction under Article 5 of the Road Traffic Act.
