For a lane to be considered reversible, it must be set up and marked as such (double dashed lines on each side of the lane). In reversible lanes, traffic in one direction or the other may be regulated by lane traffic lights or other means.
Drivers travelling in a reversible lane must have at least their low-beam or dipped headlights switched on both day and night, and must not encroach on the lane to the left of the reversible lane.
