Is it allowed to make a U-turn over double white lines?

[StNolan]

U-turns are not allowed over double white lines. Any solid line prohibits U-turns, but some areas that indeed require U-turns are marked with 'U-turn signs'. Beyond these designated areas, U-turns are not permitted. Restrictions on U-turns: 1. Vehicles are not allowed to make U-turns at locations with no U-turn or no left-turn signs and markings, as well as at railway crossings, pedestrian crossings, bridges, sharp curves, steep slopes, tunnels, or any sections of the road where it is prone to danger. 2. Vehicles can make U-turns at locations without no U-turn or no left-turn signs and markings, but they must not obstruct the normal passage of other vehicles and pedestrians.
