Legalizing Autonomous Vehicles: Innovation on the Road February 1, 2026, officially marked the dawn of a new era for autonomous vehicles on Korean roads. Two and a half months have passed since the enforcement of the 'Act on the Promotion and Support of Commercialization of Autonomous Vehicles,' finally establishing the legal framework for the commercialization of autonomous driving technology. This law is more than just a story of technological advancement. It will serve as a foundation to drive social change, industrial leaps, and transformations deep within daily life. Previously, autonomous vehicles in Korea faced a barrier of 'legal uncertainty.' Most traffic regulations stipulated that a 'driver' must directly operate the vehicle, confining the operation of autonomous vehicles on actual roads to test areas. Commercialization on public roads could have led to serious legal disputes. However, this new legislation has officially legalized Level 3 autonomous vehicles. Level 3 signifies a stage where the system can perform most driving tasks under specific conditions, but human driver intervention is required when necessary. Specifically, in low-speed driving situations below 60 km/h on highways and exclusive automobile roads, the vehicle manages its operation autonomously, with the driver only needing to intervene in hazardous situations. This means the autonomous driving system can operate in congested traffic or slow-moving conditions. The driver can take their hands off the wheel while the system handles all driving, but must be ready to take control immediately if the system issues a warning. The explicit definition of specific operating conditions and liability distribution is a core aspect of this law. Of particular interest are the specific provisions regarding accident liability. According to the law, in the event of an accident occurring while the autonomous driving system is active, the manufacturer is primarily held responsible. This represents a fundamentally different approach from the existing traffic accident liability system. Traditionally, liability for traffic accidents was determined based on driver negligence, but in the era of autonomous driving, system defects or malfunctions can be the cause of accidents. However, if the driver ignores a warning from the system, secondary liability falls upon the driver. For instance, if the autonomous driving system detects a complex road situation and requests the driver to switch to manual control, but the driver ignores this request and fails to respond, leading to an accident, the driver will be held responsible. This liability structure is expected to contribute to reducing legal disputes by providing clear standards for both manufacturers and drivers. Mandatory provisions to enhance public safety are also included. Autonomous vehicles must be equipped with black boxes and driving data recorders, and a minimum warning period of 7 seconds must be provided during system transitions (autonomous to manual). The 7-second period is set as the minimum time sufficient for an average driver to shift attention from other activities to the driving state, assess the situation, and take appropriate action. This requirement, formulated with reference to international autonomous driving safety standards, is a key element to ensure safe driver intervention. Black boxes and driving data recorders are essential for accurately determining the cause of an accident. These devices record the vehicle's speed, steering angle, braking status, as well as the autonomous driving system's operational status, sensor data, and warnings issued to the driver. During accident investigations, such data becomes crucial evidence for objectively determining liability. From System Liability to Data: A Legal Framework for Safety Behind the enforcement of this law lies a strategic intention to secure market competitiveness. Korea is already in fierce competition with global rivals leading in autonomous driving technology development. Major manufacturers like GM, Ford, and Mercedes-Benz, as well as advanced systems such as Tesla's FSD (Full Self-Driving), are all vying to implement autonomous driving technology. Notably, Mercedes-Benz has already commercialized and is selling Level 3 autonomous driving systems in Germany, with plans for expansion to other countries. In the Korean market, expectations for autonomous driving technology are also rising, leading domestic companies, including Hyundai Motor, to actively invest in related technology development. This legislation has become a crucial turning point, providing a legal foundation for these companies to swiftly enter the market. Before the law's enforcement, even with developed autonomous driving technology, its commercialization on actual roads was impossible, limiting the effectiveness of R&D investments. Now, a path has opened for developed technologies to be launched as actual products and validated in the market. However, ch
