What the exam asks about this sign

The exam asks what is compulsory in a road tunnel: dipped headlights on, enough distance (also in a queue), no U-turns or reversing, and in a breakdown put the vehicle as far to the side as possible and walk out of the tunnel. Trap: candidates pick only 'side lights', but dipped headlights are compulsory.
