Stop Line
Overview
A stop line (정지선) is a traffic safety facility marked on the road surface to indicate the position where vehicles must stop before complying with traffic signals, directions, or temporary-stop obligations under the Road Traffic Act. It is not merely a marking on the ground; it serves as a legal baseline for determining whether a driver has fulfilled the duty to stop and as key evidence in enforcement against signal violations and for pedestrian protection at crosswalks. It is installed at intersections, crosswalks, railroad crossings, school zones, and other locations, and the applicable regulations and level of penalties vary depending on its position and form.
Main Details
Definition and Marking Method
A stop line is generally a white solid line about 45 cm wide, drawn transversely across the full width of the lane. At intersections with traffic signals, it is installed immediately before the crosswalk; at intersections without signals or at temporary-stop points, it is installed immediately before entering the intersection. In sections requiring special caution, such as school zones, yellow stop lines or colored guide lines on the road surface are installed together to improve visibility. Where necessary, the word STOP or a temporary-stop sign (red octagonal sign) is installed alongside the stop line.
Purpose and Function
First, it provides a physical standard by which compliance with signals can be objectively judged. Second, it secures a safe distance between pedestrians intending to enter the crosswalk and vehicles. Third, it prevents intersection blocking (gridlocking, in which a vehicle enters an intersection and then stops), thereby reducing congestion of the entire intersection. Fourth, it induces mandatory stopping at locations with high accident risk, such as railroad crossings and school zones.
Classification by Type
- Stop line at signalized intersection: The position at which a vehicle must stop when the traffic light is red. If a vehicle stops after crossing the stop line, it is treated as a signal violation.
- Stop line before a crosswalk: A stop line for pedestrian protection; vehicles must stop when pedestrians are crossing or are about to cross.
- Temporary-stop line: A point at an intersection without signals or on a road with a stop sign where a vehicle must come to a temporary stop and then proceed slowly.
- Stop line before a railroad crossing: A duty to stop before entering the crossing and to check left and right is imposed.
- Stop line in a school zone: Often marked in yellow and operated together with time-specific traffic restrictions and slow-driving regulations.
- Roundabout yield line: A yield marking in the form of an inverted triangle, distinct from a stop line, indicating the duty of entering vehicles to yield.
Related Laws and Penalties
The Road Traffic Act stipulates the duty to obey signals and directions, intersection traffic methods, and the duty to protect pedestrians, and crossing the stop line is interpreted as a violation of these provisions. For signal violations (including crossing the stop line), a fine of 60,000 won and 15 penalty points are imposed for passenger cars, and if an accident occurs, criminal liability and civil liability for damages may also arise. Intersection blocking and failure to comply with the stop line before a crosswalk are also subject to enforcement, and recently, cases detected through unmanned enforcement equipment and CCTV image analysis have increased. Meanwhile, whether a vehicle stopped just before the stop line or crossed it is judged by comprehensively considering recorded footage and the circumstances at the scene, so drivers are required to practice defensive driving that takes into account the distance to the vehicle ahead and the remaining signal time.
Misconceptions and Precautions
A stop line is not a line at which one may stop after crossing it, but a line that must not be crossed. Therefore, stopping after crossing the stop line and then reversing is not recommended because it may rather increase the risk of an accident. In addition, when entering recklessly on a yellow signal, whether a signal violation has occurred is judged based on the moment of passing the stop line, so sufficient deceleration is necessary before entering an intersection.
Recent Trends
With the amendment to the Road Traffic Act that took effect on January 22, 2023, the duty to come to a temporary stop at the stop line and before a crosswalk when turning right was clarified, and as enforcement began in earnest after a guidance period, the meaning of the stop line drew attention again. In 2024–2025, unmanned enforcement based on smart intersections and AI image analysis expanded, increasing the accuracy of detecting stop-line violations, and facilities that enhance visibility, such as road-surface traffic signals and luminous stop lines, are being disseminated mainly by local governments. In the field of autonomous driving, work is underway to standardize and load stop-line coordinates and attribute information into high-precision road maps, and in school zones and senior protection zones, safety facilities combining yellow stop lines and speed enforcement equipment are increasing. At the same time, with policies expanding pedestrian-priority roads and roundabouts, the need for driver education on the functional distinction between stop lines and yield lines is growing.
