Ongoing lanes are limited in that automobiles turning from a aspect Avenue might not cross above the double white line to enter the continual lane, and no lane variations are permitted to the continuous lane from an adjacent lane or from the continuous lane to an adjacent lane until eventually the double white line is passed.
