In which of the following situations is performing a U-turn specifically prohibited?

Question

DentroTest · Accepted Answer

General Traffic Regulations state that U-turns are prohibited in tunnels, underpasses, and road sections marked with the 'Tunnel' sign (S-5). This rule exists for critical safety reasons: visibility in tunnels is often reduced (due to lighting changes), and space is confined, so blocking the lane to maneuver could cause serious accidents. While U-turns are also prohibited where visibility is insufficient, broken lines alone do not prohibit them (if visibility is good), and a prohibition on overtaking does not always imply a prohibition on U-turns if vertical signage explicitly allows it.
