Drunk Driving Offense | Requesting a Formal Trial of the Drunk Driving Summary Order and Obtaining an Acquittal
This is the story of a client who sought assistance, saying that he had received a summary order imposing a fine for the offense of drunk driving. The client was able to obtain a judgment of acquittal with the assistance of a drunk driving attorney.
1. The Client Who Received a Summary Order for the Drunk Driving Offense
This is the story of a client who sought the assistance of a drunk driving specialist attorney, stating that he had received a summary order for a fine for the crime of drunk driving.
The client stated that on the day of the incident, after finishing work, he had a light drink and then tried to sleep in his car.
He then woke up and drove in order to return home, and he was measured at a blood alcohol concentration of 0.03% by police conducting a drunk driving crackdown, making him subject to punishment for the crime of drunk driving.
After being referred to the prosecutors, the client was indicted by summary indictment, and the court accepted this and issued a summary order for a fine.
Stating that there were points he found unjust, the client came to this firm and asked whether requesting a formal trial against the summary order could lead to an acquittal.

2. Explanation of the Drunk Driving Offense
🔗A drunk driving offense refers to the act of operating a car, motorcycle, bicycle, or similar vehicle while intoxicated, in violation of the Road Traffic Act.
Because the law provides that the mere fact of driving while intoxicated is punishable, a person is subject to punishment even if no traffic accident results.
Under the current Road Traffic Act, a blood alcohol concentration of 0.03% or higher is regarded as a drunk driving offense, and the administrative disposition (license suspension or revocation) and the level of criminal punishment vary depending on the reading.
Under the Road Traffic Act, an intoxicated state means a state in which normal driving is difficult, and this standard is assessed comprehensively, considering not only the blood alcohol concentration but also the judgment of the police, the condition of the driver, and similar factors.
▪ Types of drunk driving
Drunk driving accident: personal injury or property damage occurs
Fleeing after drunk driving (so-called hit-and-run)
Habitual drunk driving: aggravated punishment when detected two or more times
Penalties for the Drunk Driving Offense
The level of punishment for the crime of drunk driving is classified according to blood alcohol concentration as follows.
| Blood Alcohol Concentration | Level of Punishment |
| 0.03% or more but less than 0.08% | Imprisonment for up to 1 year or a fine of up to 5 million won |
| 0.08% or more but less than 0.2% | Imprisonment for not less than 1 year but not more than 2 years, or a fine of not less than 5 million won but not more than 10 million won |
| 0.2% or more | Imprisonment for not less than 2 years but not more than 5 years, or a fine of not less than 10 million won but not more than 20 million won |
| Refusal of a breathalyzer test | Imprisonment for not less than 1 year but not more than 5 years, or a fine of not less than 5 million won but not more than 20 million won |
If a person commits the crime of drunk driving two or more times within 10 years, the level of punishment becomes higher, so caution is required.
3. The Attorney Who Took On the Drunk Driving Offense Response
This firm’s attorney responded as follows in order to obtain an acquittal for the client in a drunk driving offense.
The Possibility of Being in the Rising Phase of Blood Alcohol Concentration
The attorney argued that the possibility could not be excluded that, up to the time the client drove and the time the blood alcohol concentration was measured, the blood alcohol concentration had been in its rising phase.
Although there are individual differences, blood alcohol concentration is known to reach its peak between 30 and 90 minutes after drinking, and thereafter to decrease by an average of about 0.015% per hour.
The attorney emphasized that, during the time between the client's final drinking and the breath test, the client's blood alcohol concentration is presumed to have still been rising.
The attorney therefore argued that, because the blood alcohol concentration of 0.03% measured for the client exceeded the punishment threshold of 0.03% by only 0.003%, it cannot be conclusively determined that the client's blood alcohol concentration at the actual time of driving exceeded the punishment threshold.
In a Criminal Trial, a Conviction Requires Proof Beyond a Reasonable Doubt
According to Supreme Court Decision 2010Do5852, rendered on September 9, 2010, and other precedents, a finding of guilt in a criminal trial must be based on evidence with probative value sufficient to give the judge a conviction that the charged facts are true beyond a reasonable doubt.
If there is no evidence to form such a degree of conviction, then even if suspicion of guilt arises, the matter must be decided in favor of the defendant.
Citing this precedent, the attorney argued that the blood alcohol concentration measured at the time of the client's incident alone was insufficient to find that the charged fact that the client had driven while intoxicated had been proven beyond a reasonable doubt.
