The police are launching a special crackdown to prevent a series of drug-impaired driving accidents.
On March 31, the National Police Agency announced that an amendment to the Road Traffic Act, which strengthens the penalties for drug-impaired driving, will go into effect on April 2. Under the revised law, anyone found driving a vehicle while under the influence of drugs to the extent that it impairs their ability to drive safely will face harsher penalties: imprisonment of up to five years or a fine of up to 20 million won, increased from the previous maximum of three years' imprisonment or a fine of up to 10 million won. Refusing to submit to drug testing will also be punished in the same way as drug-impaired driving.

This special operation will target not only nightclubs and entertainment districts but also areas near large hospitals.
Unlike drunk driving checkpoints, which detect only alcohol, drug-impaired driving checks require screening for as many as 490 different substances. Furthermore, because there are no standardized measurements, more detailed procedures such as assessing the driver’s ability to operate a vehicle are required.
If officers spot a vehicle exhibiting signs of drug-impaired driving, such as zigzag driving, they will first assess the driver’s driving behavior, appearance, speech, and attitude. If deemed necessary, the officer will ask the driver to step out of the vehicle and conduct an initial roadside assessment, which includes walking in a straight line, turning, and standing on one foot. Next, a field drug test will be administered to check for the presence of drugs. If the result is positive, the officer will request a urine or blood test. Even if the field drug test is negative, if the officer believes-based on the driver’s condition or the results of the roadside assessment-that the driver may have taken substances not detected by the field test, the officer may still request a urine or blood test.
A police official explained, "Drug-impaired driving is now subject to the same penalties as drunk driving, and refusing to be tested is also punishable. Therefore, we have strengthened the procedures for collecting objective indicators and evidence necessary for enforcement." The official added that police officers have received additional training and guidance to prevent human rights violations during the relatively complex enforcement process.
Ho Seung Kim, Director of the Traffic Bureau at the National Police Agency, stated, "We ask for your cooperation with the procedures, even if they may be inconvenient," and pledged, "We will do our utmost to ensure that no innocent citizen is harmed as a result of drug-impaired driving."
