A. Whenever any street or highway has been divided into separate roadways by leaving an intervening space or by a physical barrier or clearly indicated dividing sections so constructed as to impede vehicular traffic, every vehicle shall be driven only upon the right-hand roadway, unless directed or permitted by official traffic-control devices to use another roadway.
B. No vehicle shall be driven over, across or within any dividing space, barrier or section, except through an opening in the physical barrier or dividing section or space or at a crossover or intersection as established, and then only if the movement is not specifically prohibited by official signs and markings. However, this subsection does not prohibit a left turn across a median island formed by standard pavement markings or other mountable or traversable devices when the movement can be made in safety and without interfering with, impeding, or endangering other traffic lawfully using the highway as required in section 10.2.102 of this chapter. (1968 Code §6-10-1; Ord. 75-86; Ord. 88-151; Ord. 90-81; Ord. 01-42)
