12 Grave Negligence Traffic Offenses Lawyer | What every at-fault driver needs to understand first
Summary
The Act on Special Cases Concerning the Settlement of Traffic Accidents (교통사고처리특례법) normally lets an at-fault driver avoid prosecution if the victim doesn't want punishment or the driver carries valid insurance (교통사고처리특례법 제3조 제2항). But for 12 specific types of grave negligence — signal violations, crosswalk accidents, drunk driving, and others — this protection does not apply, and the driver can be prosecuted even with full insurance and even if the victim forgives them (교통사고처리특례법 제3조 제2항 단서). On top of the criminal case, a separate administrative process under the Road Traffic Act can suspend or revoke your driver's license. These two tracks run independently, so a favorable outcome in one does not automatically fix the other.

12 Grave Negligence Traffic Offenses | The 12 Categories of Grave Negligence
Article 3(2) of the Act on Special Cases Concerning the Settlement of Traffic Accidents (교통사고처리특례법 제3조 제2항 단서) lists 12 specific circumstances where the usual insurance/settlement defense does not apply. If your accident falls under any of these, prosecution can proceed regardless of insurance status or the victim's wishes.
No.1-2
Signal/sign violation & center line crossing
Running a red light, ignoring a stop sign, or crossing over the center line into oncoming traffic are treated as inherently dangerous conduct. Whether the signal was actually red at the moment of impact, or whether crossing was involuntary (e.g., to avoid a sudden obstacle), is frequently disputed using black box and CCTV footage.
No.3
Speeding over the limit by 20km/h or more
Exceeding the posted speed limit by 20km/h or more at the time of the accident triggers this category. The actual speed is usually reconstructed from black box data, skid marks, or National Forensic Service analysis, and disputing the calculated speed is a common defense angle.
No.4
Improper overtaking or lane change violations
This covers overtaking in a no-passing zone or violating lane-change methods set by the Road Traffic Act. Whether the maneuver itself, rather than the other driver's sudden movement, actually caused the accident is often the central issue.
No.5
Railroad crossing violation
Passing through a railroad crossing without stopping or while the barrier is down falls here. These cases are relatively rare but carry a similar structure of dispute over whether the safety measures were clearly perceivable.
No.6
Failure to protect pedestrians at a crosswalk
Striking a pedestrian who is crossing, or beginning to cross, within a marked crosswalk is one of the most frequently prosecuted categories. Whether the pedestrian had actually entered the crosswalk, and whether the pedestrian signal was in the driver's favor, are the key facts.
No.7-8
Driving without a license & drunk/drugged driving
Driving without a valid license, or while under the influence of alcohol or drugs to the point that safe driving is impaired, both qualify. A DUI blood alcohol level also separately triggers penalties under the Road Traffic Act (도로교통법 제44조), so this often becomes a dual-track case.
No.9-10
Sidewalk intrusion & door-related injuries
Driving onto a sidewalk and injuring a pedestrian there, or causing injury by improperly opening a vehicle door while it is being boarded or alighted, are both included.
No.11-12
Failure to protect child/school zone pedestrians & failure to secure passengers
Accidents in designated child protection zones (school zones) and failure to ensure passenger safety, such as improper securing in a moving vehicle, round out the list. School zone cases can also trigger enhanced sentencing under the Act on Special Cases Concerning the Punishment of Specific Crimes (특정범죄 가중처�벌 등에 관한 법률).
Even outside these 12 categories, this doesn't mean automatic exoneration
If the accident does not fall into any of the 12 categories, the driver may still avoid prosecution when the victim does not wish to press charges or the driver carries valid insurance (교통사고처리특례법 제3조 제2항). However, in cases causing death, or where the driver fled the scene without providing aid (violation of duty under 도로교통법 제54조), prosecution can proceed regardless of these 12 categories. Each case needs to be checked against both the general rule and its exceptions.
12 Grave Negligence Traffic Offenses | How Criminal Exposure Actually Plays Out
Being charged under one of the 12 categories does not automatically mean a harsh sentence, but it does mean the case proceeds through the criminal justice system rather than being closed early. Understanding the realistic range of outcomes helps set expectations from the start.
Prosecution track: summary order vs. formal indictment
Most first-time offenders in less severe cases (e.g., minor injury from a signal violation) are processed by summary order (약식명령), which typically results in a fine without a court appearance. More serious cases — death, repeat offenses, or combination with DUI — are more likely to proceed to formal trial (정식기소), which carries the possibility of imprisonment under Article 268 of the Criminal Act (형법 제268조) for causing death or injury through negligence in the course of an occupation.
Why a written apology and settlement still matter
Even though the victim's wish for leniency cannot stop prosecution under the 12 categories, an early written settlement or expression of forgiveness from the victim remains one of the most significant sentencing factors considered by prosecutors and judges (형법 제51조, general sentencing factors). Documenting sincere efforts to compensate the victim, separate from insurance payouts, is often the single most effective thing a driver can do.
Aggravating and mitigating facts specific to your category
The specific category matters for how the case is argued. A crosswalk case turns heavily on pedestrian signal timing and the pedestrian's visibility, while a DUI case turns on the measured blood alcohol concentration and how it was obtained. Building the defense around the facts unique to your specific category, rather than treating all 12 the same, tends to produce a more accurate risk assessment.
Separately from the criminal case, the police and the Korean National Police Agency's driver's license authority run their own point-based administrative process under the Road Traffic Act. This can result in suspension or revocation of your license even before, or regardless of, how the criminal case ends.
How points accumulate for 12-category accidents
Causing injury or death, combined with the fault-finding for the specific violation (e.g., signal violation, DUI), generates points under the administrative point system established under the Road Traffic Act (도로교통법) and its enforcement rules. Reaching certain point thresholds within a set period triggers automatic suspension, and higher thresholds trigger revocation.
Filing an administrative appeal or objection (이의신청/행정심판)
A driver who disputes the suspension or revocation decision can file an objection with the police agency or pursue an administrative appeal (행정심판) before the relevant committee, and in more serious cases an administrative litigation (행정소송) challenging the disposition. These procedures have their own short deadlines, so acting quickly after receiving the notice matters.
Relief for drivers who depend on their license for work
Where license revocation would eliminate a driver's livelihood (e.g., commercial drivers, delivery workers), some relief is available through a hardship exception review process, though this depends heavily on the specific violation category — DUI cases, for example, face much stricter thresholds for relief than a simple signal violation.
12 Grave Negligence Traffic Offenses | What Insurance Does and Doesn't Cover Here
A common misconception is that having full comprehensive auto insurance eliminates all risk in a 12-category accident. Insurance affects civil compensation to the victim, but it has a much more limited effect on the criminal case once one of the 12 categories applies.
Civil compensation still proceeds through the insurer
Regardless of criminal outcome, the insurer typically handles compensation negotiations with the victim for medical expenses, lost income, and pain and suffering. This process runs on its own timeline and settlement standards, separate from the criminal case.
Why the insurance defense doesn't apply to the 12 categories
Normally, having entered into a comprehensive insurance contract that fully covers the damages allows the case to be closed without prosecution (교통사고처리특례법 제4조 제1항). But this defense is expressly excluded for the 12 categories listed in Article 3(2) (교통사고처리특례법 제4조 제1항 단서), meaning the insurance payment itself becomes largely irrelevant to whether you get prosecuted.
Recovering from a DUI or unlicensed-driving insurance exclusion
Some policies allow the insurer to seek reimbursement from the driver personally (구상권 청구) in DUI or unlicensed-driving cases, since these are often excluded from standard coverage terms. Reviewing the specific policy terms early helps the driver anticipate this separate financial exposure.
12 Grave Negligence Traffic Offenses | From the Accident Report to Case Resolution
1
Initial police investigation & accident report Police collect black box footage, CCTV, witness statements, and issue a preliminary fault assessment. What you say at this stage in your statement is frequently referenced later, so early legal input matters.
2
Referral to prosecution & charge decision The case file moves to the prosecutor's office, which decides whether to pursue summary order, formal indictment, or in rare cases non-prosecution if a statutory exception applies despite the initial 12-category flag.
3
Parallel administrative license review Independently, the police licensing division calculates points and issues a suspension/revocation notice. This can arrive before the criminal case concludes and has its own appeal deadline.
4
Settlement negotiation with the victim Whether through the insurer or directly, working toward a written settlement or statement of non-objection from the victim is pursued in parallel, since it affects sentencing even though it cannot block prosecution outright.
5
Trial or summary order outcome & license appeal decision The criminal case concludes with a fine, suspended sentence, or in more serious cases imprisonment, while the administrative appeal (if filed) proceeds on its own track toward a final decision on the license.
12 Grave Negligence Traffic Offenses | How Fees Are Typically Set
Retainer (착수금) Usually set based on whether the case is expected to proceed by summary order or full trial, and whether an administrative license appeal is being handled alongside the criminal case. A combined criminal + administrative engagement is typically priced as a package rather than two separate full fees.
Success fee (성공보수) If used, this is generally tied to concrete outcomes such as securing non-prosecution, a reduced charge, a suspended sentence instead of imprisonment, or successfully overturning a license suspension/revocation on appeal.
Administrative appeal costs (행정심판/행정소송 관련) Filing an objection or administrative appeal against a license disposition, and if necessary an administrative litigation, involves separate procedural fees and, for litigation, court filing costs distinct from the criminal defense fee.
Disbursements (실비) Costs such as obtaining accident reconstruction reports, expert opinions on speed or signal timing, and copies of the case file are billed separately as they are incurred.

12 Grave Negligence Traffic Offenses | Self-Check Before Your Consultation
1️⃣ Does your accident actually fall under one of the 12 categories?
Was the traffic signal or stop sign clearly in effect at the moment of the accident, based on black box or CCTV footage?
Was the pedestrian already inside the marked crosswalk boundary, or just approaching it?
Was your measured speed at the time of impact actually 20km/h or more above the posted limit?
Did the accident occur within a designated child protection zone (school zone) during restricted hours?
Was there any drug or alcohol influence, and if so, how was the measurement taken and recorded?
2️⃣ Criminal case status check
Have you already given a statement to police, and do you remember exactly what you said?
Has the case been referred to the prosecutor's office yet, or is it still under police investigation?
Have you received any written notice of summary order, or a summons for questioning or trial?
Have you attempted to contact the victim, and if so, is there any written record of that contact?
3️⃣ License / administrative status check
Have you received a notice of license suspension or revocation from the police licensing division?
Do you know the exact deadline stated on that notice for filing an objection or appeal?
Does your job or livelihood depend directly on holding a valid driver's license?
Have prior violations added points to your license within the relevant look-back period?
4️⃣ Insurance and civil compensation check
Does your insurance policy exclude coverage for DUI or unlicensed driving, and have you reviewed those exclusion clauses?
Has your insurer already opened a claim with the victim, and do you know the current settlement status?
Have you been notified of a possible indemnity claim (구상권) from your own insurer?
Frequently Asked Questions
Q. I have full comprehensive insurance — can I still be prosecuted?
A. Yes. For the 12 categories listed under the Act on Special Cases Concerning the Settlement of Traffic Accidents (교통사고처리특례법 제3조 제2항 단서), having full insurance coverage does not prevent prosecution, unlike ordinary traffic accidents. The insurance defense under Article 4 is expressly excluded for these categories (교통사고처리특례법 제4조 제1항 단서).
Q. The victim already said they won't press charges — does that end the case?
A. Not automatically, if the accident falls under one of the 12 categories. Because these are prosecuted independently of the victim's wishes (교통사고처리특례법 제3조 제2항 단서), the case can still proceed, though the victim's statement is a meaningful factor in sentencing.
Q. Will I definitely go to prison for a crosswalk accident?
A. Not necessarily. Many first-time, minor-injury cases are resolved through summary order (약식명령) resulting in a fine, without a court appearance. Whether the case proceeds to formal trial with the possibility of imprisonment under Article 268 of the Criminal Act (형법 제268조) depends on the severity of injury, prior record, and case-specific facts.
Q. Can my license be suspended even if the prosecutor decides not to charge me?
A. Yes, because the criminal and administrative processes are separate. The police licensing division applies its own point system under the Road Traffic Act (도로교통법), so a favorable outcome in the criminal case does not automatically stop or reverse a license suspension or revocation.
Q. How do I appeal a license suspension or revocation?
A. You can file an objection with the police agency, or pursue an administrative appeal (행정심판) before the relevant committee, and if necessary an administrative litigation (행정소송) challenging the disposition. These have their own filing deadlines stated on the notice you receive, separate from any criminal case deadlines.
Q. What counts as speeding under the 12 categories — any amount over the limit?
A. No. This specific category requires driving at least 20km/h over the posted speed limit at the time of the accident. Lower amounts of speeding may still be considered as a general fault factor, but they do not by themselves trigger the 12-category exclusion.
Q. Does a hit-and-run count as one of the 12 categories?
A. Fleeing the scene without providing aid is generally treated as a separate, more serious violation under the Road Traffic Act's duty-to-render-aid provision (도로교통법 제54조) rather than one of the 12 listed categories itself, and it can trigger prosecution and enhanced penalties independently of whether the underlying accident falls into one of the 12 categories.
Q. Is a school zone (child protection zone) accident always treated more harshly?
A. Accidents in designated child protection zones causing injury to a child are subject to this category and can also trigger enhanced sentencing under the Act on Special Cases Concerning the Punishment of Specific Crimes (특정범죄 가중처벌 등에 관한 법률), which is generally handled more strictly than a similar accident outside such a zone.
Q. If I was driving without a license because it had expired, does that count?
A. Whether an expired or suspended license is treated the same as never having held one can depend on the specific circumstances, such as how long it had been expired and whether renewal notices were given. This is a fact-specific issue worth reviewing with counsel rather than assuming either outcome.
Q. Can settlement with the victim after the fact still help even though it can't stop prosecution?
A. Yes. A documented settlement or the victim's written statement of forgiveness remains one of the strongest mitigating factors considered at sentencing, even in 12-category cases where it cannot prevent the case from being prosecuted in the first place.
