Which sections of road prohibit U-turns?

[TravisLynn]

During vehicle operation, the following road sections do not permit U-turns: 1. No-left-turn intersections: Intersections marked with no-left-turn signs prohibit left turns. 2. Crosswalk areas: Some roads have pedestrian crossings. Although these areas typically lack explicit no-U-turn signage, they are legally equivalent to sidewalks where U-turns are prohibited. 3. Leftmost lane with straight-only arrow: Near intersections, lane arrows guide drivers in lane selection. If the leftmost lane displays only a straight arrow, U-turns are prohibited even in the absence of specific no-U-turn signage.
