A transportation barrier is a natural barrier like mountains, rivers, oceans, etc that blocks or slows the way of transportation.
Two sets of solid double yellow lines spaced 2 feet or more apart are considered a barrier. Do not drive on or over this barrier, make a left turn, or a U-turn across it, except at designated openings (see diagram). Solid white lines mark traffic lanes going in the same direction, such as one-way streets. Broken white lines separate traffic lanes on roads with two or more lanes in the same direction. Double white lines are two solid white lines that indicate a lane barrier between a regular use and a preferential use lane, such as a  carpool/HOV.
