On a road with reversible (variable) lanes whose direction is set by traffic lights, what is the "centerline" under the Road Traffic Act?
The centerline is the line separating the directions of traffic, but there is a proviso that where reversible lanes are installed it is determined by the direction indicated by the traffic light (Article 2, subparagraph 5 of the Road Traffic Act). Check the color (yellow or white), the type (solid or dashed) and the position (leftmost or rightmost) together.
Answer: ②
Explanation
Under the proviso of Article 2, item 5 of the Road Traffic Act, where reversible lanes are installed, the centerline is the yellow dashed line at the far left of the direction of travel indicated by the traffic light. Because the direction changes by time of day, the position of the centerline also changes with the signal. Reversible lanes still have a centerline, so using any lane freely is wrong.
