One of the main causes for traffic accidents in our country is drunk-driving. Legislators build the legal framework of traffic order by both Criminal Code and Act Governing the Punishment of Violation of Road Traffic Regulations. Also, to prevent the possible loopholes of drunk-driving regulations, legislators would continually cumulate penalty for those refuse to accept alcohol concentration test. This article aims to clarify the constitutionality of the revocation of all types of driver's licenses for simply refusing alcohol concentration test in accordance with Act Governing the Punishment of Violation of Road Traffic Regulations. First, the Judicial Yuan Interpretation No. 699 will be reviewed. Then, various types of fundamental rights that could be violated would be discussed, including the freedom of movement, the right to life and work and the right to equality. By comparing with the Behavior of drunk-driving and refusing alcohol concentration test, the personal observation and reflection about this Theme would also be presented. After examining, the regulations in Act Governing the Punishment of Violation of Road Traffic Regulations cannot match the principle of proportionality of Article 23 in the Constitution, therefore, there's a serious concern for disproportionately limitation for relevant fundamental rights, which should not be neglected.
