I caused a DUI traffic accident and injured someone.

To get straight to the conclusion, if you cause a DUI traffic accident and injure someone while driving under the influence of alcohol, you may receive both criminal punishment and driver's license sanctions simultaneously.

If you injure a person while driving in a state where normal driving is difficult due to alcohol or drugs, the Act on the Aggravated Punishment, etc. of Specific Crimes applies, and the sentence becomes higher.

This may result in imprisonment for 1 to 15 years or a fine between 10 million and 30 million won under Article 5-11(1) of the Act on the Aggravated Punishment, etc. of Specific Crimes.

In addition, if you fail to take necessary measures after the DUI traffic accident or violate driver's license-related laws, your driver's license may be revoked and you may be subject to a certain period of license acquisition restriction.

Therefore, in this DUI traffic accident case, since it is judged not as simple negligence but as an accident involving drunk driving, both criminal disadvantages and administrative sanctions are highly likely to apply.
