Which statement about lane installation standards and lane numbering is NOT correct?
💡 Hint
Lanes are numbered starting from the centerline side, and for one-way roads, which have no centerline, a separate rule sets which side lane 1 starts from (Article 16 of the Enforcement Rule). Also check the lane widths of 3 meters and 275 centimeters and the places where lanes may not be installed (Article 15).
Answer: ③
Explanation
Under Article 16(3) of the Enforcement Rule, lanes are numbered from the one next to the centerline, and on a one-way road from the left side, so numbering from the right is wrong. Article 15 of the Rule sets lane width at 3 meters or more (275 centimeters or more when unavoidable) and prohibits lanes on crosswalks, intersections and railroad crossings.
