内容摘要：我国刑法规制交通肇事逃逸，其主要目的是为了用法律的手段以保证行为人对被害人的及时救助，从而避免肇事行为引起更大的不必要的社会危害以及个人人身、财产的损失。交通肇事逃逸的前提条件是行为人主观上明知自己已经发生交通事故，只有当行为人主观上已经认识到发生交通事故的情况下，才能谈得上“逃逸”。重处逃逸行为就是为了最大程度地保护法益。刑法具有制裁手段的严厉性特征，由于交通肇事罪是一种过失犯罪，因此刑法规定了较轻的法定刑，但一旦行为人在肇事后逃逸的，他的主观状态就从过失肇事转化为故意离弃被害人，这种主观恶性已经不是交通肇事罪的基本法定刑所能规制的了，因此，需要采取更为严厉的处罚方法，才能保证罪行相适应。处理交通肇事后的逃逸行为要在法律明文规定的构成要件和法定刑的限度内，正确适用法定刑，从而达到有效遏制交通肇事后逃逸的发生以及形成良好的社会秩序和交通环境的目的。

Abstract: The main purpose of punishing hit-and-run in the Criminal Law is to use legal methods to ensure the actor's timely salvation to the victim, and then avoid greater unnecessary social harms, personal and property losses. The precondition of traffic escapes is that the actor is aware of having had the traffic accident, for only when the actor subjectively has realized the traffic accident, the "escape" can be said. Severe punishment on the escape behavior is to maximally protect the legal interest. The criminal law has a characteristic of tough sanctions. For the traffic accident crime is a kind of criminal negligence, the criminal law has the lighter legally-prescribed punishment. However, once the actor ran after the accident, the subject state of him has transformed from the negligence to the intention to desert the victim. The subjective vicious state is not within the basic legally-prescribed punishment and more severe methods should be adopted to suit punishment to crime. We should apply correctly within the constitutive requirements of the law and the limitation of legally-prescribed punishment when dealing with traffic accident escapes, so as to achieve an effective control of the traffic escape and create good social order and traffic environment.
