Business operators and vehicle managers reviewing documents on repeat drunk-driving violations tend to look for a single rule like "a repeat offense means X years." But the provision that aggravates criminal penalties for repeat offenses and the provision that decides who must get a conditional driver's license requiring an alcohol interlock differ in purpose and in the starting point for counting the period. Even within a single case, the violation date, the date the sentence became final, and the date of the license revocation order can all be different days.
An alcohol interlock is a device provided for in Korea's Road Traffic Act together with the conditional driver's license, and a conditional driver's license is a license issued on the condition that this device is installed. The key distinction in this article is between the 10 years for criminal repeat-offense aggravation and the 5 years for judging eligibility for a conditional license. You also need to keep separate the fact that the device installation period for a conditional license is calculated apart from the period for judging a repeat violation.
Criminal repeat-offense aggravation and the conditional license ask different questions
Article 148-2(1) of the Road Traffic Act is a penalty provision setting criminal punishment for a person who commits a violation again after an earlier one. Its structure covers a person who, while driving a motor vehicle, etc., or a tram, violated Article 44(1), (2), or (5) and was sentenced to a fine or heavier penalty, and who then commits a violation within the same scope again after that sentence became final. Riding a personal mobility device is excluded from the scope of this provision.
Article 80-2(1), on the other hand, sets out who must obtain a conditional driver's license requiring an alcohol interlock. It does not look only at the time between the earlier violation and the later one; it also considers whether the person received a license revocation order for the later violation, or whether the repeat violation was accompanied by a violation of provisions such as driving without a license. So you cannot conclude from the fact of a second violation alone that the person must get a conditional license.
The 10 years are counted from the date the sentence became final
The starting point for the 10 years in Article 148-2(1) is not the violation date of the past case but the date a sentence of a fine or heavier became final. The intake date, enforcement date, report date, or license sanction date cannot stand in for the date the sentence became final. That is why a note saying only that there was a past violation is not enough to calculate the period under this provision.
Article 44, which this provision refers to, distinguishes the prohibition on driving while intoxicated, the duty to comply with a police officer's breath test, and acts obstructing a test, such as drinking more or using certain substances in order to make testing difficult. When working out whether repeat-offense aggravation applies, you also need to check, separately from the dates, whether the past case and the later case each fall within the scope of violations the provisions set out.
The 5 years are counted from the violation date of the earlier violation
The 5 years in Article 80-2(1) are counted from the date the earlier violation was committed. When a fine or other sentence in the criminal case later became final does not change the starting point of these 5 years. The date of the license revocation order for the later violation is also not stated as the reference date for calculating the 5-year repeat-violation period.
| Question to distinguish | Starting point of the period | What to look at besides the period |
|---|---|---|
| Does criminal repeat-offense aggravation apply? | The date a sentence of a fine or heavier became final | Whether the later violation occurred within 10 years, and the scope of the violation |
| Is the person subject to a conditional driver's license? | The violation date of the earlier violation | Whether the later violation was within 5 years, and additional requirements such as license revocation |
| When does the device installation period start? | The day after the license disqualification period ends | Whether the device stays installed for a period equal to the disqualification period |
The third row of the table is there to avoid confusing "a repeat violation within 5 years" with the device installation period. Article 80-2(2) provides that the device is installed for a period equal to the license disqualification period that applies to the person subject to a conditional license, and that the installation period is calculated from the day after the disqualification period ends. In other words, the 5 years are the period that decides whether someone is subject to a conditional license; they do not mean the device is installed for 5 years.
Records with missing dates are not grounds for a determination
As a hypothetical example, consider a vehicle management record that says only "2021 drunk driving, 2025 repeat violation." The facts observable here are only records that appear to show two incidents and the years. The exact violation date of the first incident, the date a sentence of a fine or heavier became final, whether the second incident led to a license revocation order, and what other conduct was at issue at the time of the repeat violation are unknown.
The interpretation of this record is that it is insufficient to make a determination under either the 10-year or the 5-year provision. When organizing it, you can consider listing the first incident's violation date and the date the sentence became final as separate fields, and recording the second incident's violation date, whether a license revocation was ordered, and the violations applied alongside it as separate items. The completion criterion is a state in which each date can be identified as which date of which incident, and unconfirmed values are left marked as unconfirmed rather than guessed.
If there are several incidents, it is safer to put each on a separate line. An expression like "2023 drunk driving" does not tell you whether it is the violation date, the sanction date, or the date the sentence became final. Writing the nature of each date next to it, such as "first violation date," "date sentence became final," "repeat violation date," or "license revocation order date," lowers the chance that the next reviewer plugs in the reference date for the wrong system.
Within the organization, share only the information needed for driving decisions
Organizations that manage vehicle operations need to separate information needed for criminal penalty decisions from information needed for actual operations management. What dispatch or vehicle management staff need to check may be matters directly tied to driving, such as whether there is a conditional driver's license and what conditions are attached to driving. The specific circumstances of past cases or full court judgments are not always needed for vehicle management.
In particular, the provisions that apply to past cases may differ depending on when the act occurred and when the sanction was imposed. So rather than plugging the 10 years and 5 years in the current provisions straight into past cases, organize the dates of each case separately from the provisions applied at the time. Keeping the distinction that criminal repeat-offense aggravation uses the date the sentence became final while conditional license eligibility uses the violation date is the basic rule for not confusing the two systems.
