Legal basis: In the Criminal Law of People's Republic of China (PRC), a driver who drives a motor vehicle under the influence of alcohol constitutes a crime of dangerous driving. According to the law, he can be detained for less than six months and fined, and the punishment for causing personal injury or death will be even heavier. The duty of a lawyer is to provide materials and opinions on whether a criminal suspect or defendant is innocent, light or relieved of criminal responsibility according to facts and laws, and to safeguard the litigation rights and other legitimate rights and interests of the criminal suspect or defendant.
