In Norway, yellow lines are used to separate traffic moving in opposite directions and on the left shoulders of paved roads, and white lines are used to separate traffic moving in the same direction, and on the right shoulders of paved roads. On roads narrower than , the centerline is removed, and the shoulder lines are broken. Short, broken lines means passing is allowed, long, broken lines means passing is allowed but dangerous, and a double yellow line means passing is forbidden. Roads with speed limits below that indicate that passing is allowed but dangerous have a very short yellow line instead of a long one. On motorways, the left shoulder is a yellow line, like in the US. Most other European countries use white lines for all these types of lines.
