These lanes are called “reversible lanes” and are usually marked by double-dashed yellow lines.\n\nBefore you start driving in them, check to see which lanes you can use at that time. There may be signs posted by the side of the road or overhead.\n\nSpecial lights are often used. A green arrow means you can use the lane beneath it; a red “X” means you cannot. A flashing yellow “X” means the lane is only for turning. A steady yellow “X” means the use of the lane is changing and you should move out of it as soon as it is safe to do so.",{"slug":16,"title":17,"free":18},"signals-signs-and-pavement-markings","Signals, Signs and Pavement Markings",true,{"slug":20,"title":21},"signals","Signals",1794237725448]
