South Korea Implements Mandatory Breathalysers for Habitual Drink Drivers

South Korea is set to enforce a significant policy change aimed at reducing incidents of drink driving. Starting October 24, 2026, habitual drink drivers will be required to install ignition interlock devices, commonly referred to as car breathalysers, in their vehicles. This decision follows a report from the National Police Agency (NPA) indicating that 43.3% of drink driving accidents from 2019 to 2023 involved repeat offenders. The new law mandates that individuals convicted of driving under the influence (DUI) at least twice in the past five years must have these devices installed, which measure blood alcohol concentration (BAC) through breath samples. If the BAC exceeds the legal limit, the device will prevent the vehicle from starting.

The installation of these devices is estimated to cost around three million won (approximately S$2,660). The NPA is currently discussing rental options for these devices with the Korea Road Traffic Authority. Violations of this mandate could result in fines of up to three million won or a prison sentence of up to one year, alongside potential license revocation. Additionally, attempts to bypass the system by having another person start the vehicle could lead to penalties of up to three years in prison.

The introduction of this policy is part of a broader effort to combat the high rates of repeat DUI offenses in South Korea. Between 2019 and 2023, there were 75,950 reported drink driving accidents, highlighting the urgent need for stricter measures. Recent statistics indicate that the number of repeat offenders reached 45.3% in 2024, prompting authorities to intensify punitive actions against habitual offenders. Alongside the breathalyser mandate, the government has also announced increased penalties for drug-related driving offenses, raising potential prison sentences from three to five years and fines from ten million to twenty million won, effective April 2, 2026.

The NPA has emphasized that the new regulations aim to significantly reduce drink driving incidents and enhance road safety. The agency noted, “This policy seeks to reduce drink driving cases in South Korea, a substantial number of which are repeat crimes.” Ministerial officials have expressed a commitment to enforcing these measures rigorously to restore public trust in road safety.

While the policy has been largely supported as a necessary step towards improving public safety, some critics have raised concerns about the financial burden of installing breathalysers on habitual offenders. There are also apprehensions regarding the potential for misuse of the devices and the implications for personal privacy. Critics argue that the focus should also include broader educational campaigns about responsible drinking and driving.

As the implementation date approaches, the NPA and the Korea Road Traffic Authority will finalize the logistics for device installation and rental options. Continuous monitoring and evaluation of the policy's effectiveness will be essential to ensure that it meets its objectives of reducing drink driving incidents and enhancing overall road safety in South Korea.
