Which statement about the installation of lanes and driving in them is correct?
Where lanes exist, you must follow them, and passing through a no-lane-change section or driving a vehicle wider than the lane is subject to specific exceptions or permission requirements (Article 14 of the Road Traffic Act). Also recall what a reversible lane uses to indicate its direction of travel.
Answer: ④
Explanation
Article 14(1) of the Road Traffic Act allows reversible lanes, whose direction is shown by traffic lights, on roads where traffic in each direction differs clearly by time of day. Where lanes exist you must follow them (para. 2), and where lane changes are prohibited by signs you may not change lanes unless road damage or construction creates an obstacle (para. 5). A vehicle wider than the lane needs a permit from the police station chief with jurisdiction over its departure point (para. 3).
