217. Reversible lane
A reversible lane is a traffic lane whose permitted direction of travel can be changed at different times to provide additional capacity in the direction with the greatest traffic demand. It is commonly used on roads where traffic flows strongly in one direction during certain periods and in the opposite direction at other times.
Reversible lanes are normally controlled by overhead lane signals, traffic lights, signs or movable barriers. Drivers must enter the lane only when the signals indicate that travel in their direction is permitted.

Why are reversible lanes used?
They allow road authorities to increase capacity in the busiest direction without permanently adding another traffic lane.
