3. The 12 Categories of Gross Negligence | Legal Liability

Criminal, civil, and administrative legal liability for the 12 categories of gross negligence

An accident involving the 12 categories of gross negligence is a serious legal matter in which criminal punishment, administrative disposition, and civil liability for the driver's conduct may arise at the same time.

Each liability structure is distinguished as follows.

Criminal Punishment

Even for a vehicle covered by comprehensive insurance, where the driver causes a traffic accident through a violation of the law falling within the 12 categories of gross negligence, the special case exempting criminal punishment does not apply.

Accordingly, it should be noted that criminal punishment is possible regardless of whether there is a settlement with the victim.

In the case of the 12 categories of gross negligence, criminal punishment is imposed under Article 3 of the Act on Special Cases concerning the Settlement of Traffic Accidents.

Act on Special Cases concerning the Settlement of Traffic Accidents, Article 3 (Special Cases on Punishment)Imprisonment without labor for not more than 5 years or a fine of not more than 20 million won

Administrative Disposition

An accident involving one of the 12 categories of gross negligence also meets the criteria for an administrative disposition of a license under the Road Traffic Act, so a suspension or revocation of the driver's license may be imposed.

When a driver's license is revoked, a disqualification period is imposed during which the license cannot be reacquired, and the length of that period depends on the underlying ground.

Only after this disqualification period has elapsed can the reacquisition procedures, such as applying for the license examination, proceed.

In addition, after the disqualification period has passed, the driver must complete the mandatory special traffic safety education before the driver's license can be acquired.

▶ Disqualification Period

Driving without a license1 year from the date of violation, but 5 years from the date of violation if casualties occurred and no measures were taken
Drunk driving (DUI)5 years from the date of license revocation

Civil Liability for Damages

Civil liability for damages arises with respect to the physical and property loss sustained by the victim, and such loss is generally handled through comprehensive insurance.

In the case of an accident involving one of the 12 categories of gross negligence, however, the driver may bear a portion of the burden personally, for example when the insurer makes a reimbursement claim against the driver for the amount it paid to the victim.

4. 12 Categories of Gross Negligence | Response Methods

Daeryun methods for responding to accidents involving the 12 categories of gross negligence

When a traffic accident falls within one of the 12 categories of gross negligence, the possibility of criminal punishment becomes substantially higher than in a simple negligence accident, so it is important to take the following step-by-step measures promptly.

Preservation of the Accident Scene and Reporting

Immediately after the accident, the driver should report the matter to the police at once and preserve evidence by capturing photographs or video of the scene, including dashcam footage, the condition of the vehicle damage, and the location of the victim.

If the victim is injured, rescue measures and a 119 emergency report must be carried out without omission, and these measures may also affect the level of criminal punishment imposed later.

Criminal Settlement with the Victim

In the case of an accident involving one of the 12 categories of gross negligence, it is difficult to avoid punishment without a criminal settlement, even if the driver is covered by comprehensive insurance.

For this reason, it is advisable to make active efforts toward a settlement through smooth communication with the victim's side, and it is prudent to obtain professional advice on the legal effect and formal requirements of the settlement agreement prepared at that time.

Points to Note During Police Questioning and Statements

At the investigation stage before the police or the prosecution, the driver should clearly state the circumstances of the driving conduct, the situation at the time, and whether the duty of care was fulfilled, and it can be helpful to prepare and submit a written statement or opinion if necessary.

Because an unfavorable statement can inadvertently aggravate criminal liability, obtaining the assistance of counsel from the early stage of the investigation is recommended.

Organizing Sentencing Factors and Preparing Mitigating Materials

In preparation for the possibility that the matter proceeds to trial, it is advisable to organize sentencing materials, including the circumstances at the time of the accident, efforts to remedy the harm, the driver's living circumstances, whether the driver is a first-time offender, and a letter of reflection.

In particular, a settlement with the victim, community service, and financial hardship resulting from license suspension are key factors that may be reflected in a decision on reduction of sentence or a suspended sentence.

5. 12 Categories of Gross Negligence | Procedures You Can Handle on Your Own

Immediately after a traffic accident, there are certain procedures, up to a certain level, that you can handle on your own.


For example, obtaining a traffic accident confirmation certificate, submitting a medical certificate, and reporting the accident to the insurer are steps that a driver can carry out relatively easily.

▶ How to Obtain a Traffic Accident Confirmation Certificate

You can apply through Government24, the National Police Agency Traffic Civil Affairs 24, or the Police Civil Affairs Portal, where you must enter the date the accident occurred and then complete identity verification.

Offline, you can visit the competent police station with your identification.

Confirming the accident report number in advance can speed up issuance.

When Assistance Is Needed

When an accident falls within one of the 12 categories of gross negligence, the situation changes considerably.
