South Korea Blood Alcohol Content (BAC) Legal Framework
Last Updated: 2025
Legal Framework Under Korean Traffic Law
Road Traffic Act (도로교통법)
Article 44 of the Road Traffic Act establishes universal 0.03% BAC limit for all drivers, making Korea one of the world's strictest jurisdictions. The Act was strengthened in 2018 following public demand for zero-tolerance drunk driving policies after high-profile fatal accidents.
Universal 0.03% Standard
Unlike most countries, Korea applies a single 0.03% BAC limit to all drivers regardless of age, experience, or vehicle type. This represents the world's most stringent drunk driving standard.
Three-Strike Rule (3진 아웃제)
Drivers with three DUI convictions face permanent license revocation with no possibility of reinstatement, implemented as part of Korea's "three strikes and you're out" policy.
Mandatory Vehicle Forfeiture
Repeat offenders (second conviction within 5 years) face mandatory vehicle confiscation and destruction, regardless of vehicle ownership or value.
Refusal Testing Penalties
Refusing breathalyzer tests results in automatic license suspension for 1 year and prosecution under obstruction of justice charges.

Important Information for Drivers in South Korea
Zero Tolerance Enforcement
Korea's 0.03% limit means approximately one standard drink can exceed the legal limit. Police conduct widespread random checkpoints, especially during holidays and weekends. Mobile testing units operate 24/7 in entertainment districts.
Social Stigma and Career Impact
DUI convictions carry severe social stigma in Korean society. Many employers, especially chaebols (large corporations), conduct background checks and may terminate employees with DUI records. Government positions and teaching jobs become permanently unavailable.
Three-Strike Permanent Ban
The "3진 아웃" (three strikes out) policy permanently revokes driving privileges after three DUI convictions. There is no reinstatement process, making this one of the world's harshest repeat offender policies.
Vehicle Forfeiture Program
Second-time offenders within 5 years face mandatory vehicle confiscation regardless of ownership. Vehicles are typically destroyed or auctioned, with proceeds going to traffic safety programs.
Insurance and Financial Consequences
DUI convictions void comprehensive insurance coverage and increase premiums by 200-300%. Some insurers refuse coverage entirely. Victims can pursue unlimited personal liability claims.
Public Transportation Alternative Programs
Korea offers extensive late-night public transportation and government-subsidized substitute driver services (대리운전) to prevent drunk driving. Many smartphone apps connect users with designated drivers.
Rehabilitation and Education Requirements
All DUI offenders must complete intensive 40-hour alcohol education programs and undergo psychological evaluation. Repeat offenders require certified addiction treatment before license consideration.
Digital Record and Monitoring
DUI convictions are recorded in the national digital database accessible by employers, landlords, and government agencies. High-risk drivers may be subject to electronic monitoring and mandatory check-ins.
