Which two statements about the installation of lanes are correct? Select TWO
As a rule a lane must be at least 3 meters wide, and only when unavoidable may it be narrowed to 275 centimeters or more (Article 15 of the Enforcement Rule of the Road Traffic Act). Also check what is used to mark lanes, and what is provided for pedestrians on roads with no separate sidewalk.
Answer: ②, ③
Explanation
Lanes are indicated with the road markings in Annex 6 of the Enforcement Rule, and when lanes are installed on a road without separate sidewalks, roadside areas must be provided on both sides so pedestrians can walk safely (Enforcement Rule of the Road Traffic Act Article 15(1), (4)). Lanes must in principle be at least 3 meters wide, and only when unavoidable may they be 275 centimeters or more. Lanes can be installed on roads without separate sidewalks, so the last option is wrong.
