Based on the concept and theory of liability without fault, this article discusses the 76th statute in the Law of On-road Traffic Safety, which says that the liability without fault gauge will be applicable if there is an accident between motor vehicle and a non-motor vehicle or pedestrians. It also elaborates the significance of the principle of applying the liability without fault in traffic accident cases. It means that besides intentionally, the non-motor vehicle driver or pedestrians don`t have to pay the loss of the side of motor vehicle, even though there is a severe mistake by non-motor vehicle driver or pedestrians. This conclusion disaffirms that the damaged motor vehicle may claim for compensation to the non-motor vehicle driver or pedestrians.
