本文对道路交通事故预防的提前识险定理进行了补充，一是补充了提前识险定理的含义。二是从事故发生的原因出发，分析了道路交通安全(即事故)的特点与事故危险的本质来源，在对本质来源的事故危险程度进行分类的基础上，提出了提前识险定理的3个原则。三是分析了我国目前不足的事故危险来源，在对不足来源的事故危险程度进行分类的基础上，又提出了提前识险定理的3个原则。四是指出提出原则(共6个)的目的，既是为了还原道路交通安全的本来面目，更是为了对道路交通事故预防提供真实理念。
This thesis complements the hazard anticipation principle of road traffic accident prevention. Firstly, the definition of hazard anticipation principle is supplemented. Secondly, the origin of characteristics and hazardous nature of road traffic accident on the basis of the reasons of accidents is analyzed. On the basis of classifying the accident original hazard levels, this thesis proposes three principles of hazard anticipation principle. Thirdly, another three principles of hazard anticipation principle are put forward according to the analysis of our national inadequate accident hazard origin based on the classification of these accidents hazard levels. Fourthly, the goal of these six principles is pointed out, which not only can restore the true features of road traffic accidents but also provides the true theory for road traffic accident prevention.
