Whenever any street or highway has been divided into two roadways by leaving an intervening space or by a physical barrier or clearly indicated dividing section so constructed as to impede vehicular traffic, every vehicle shall be driven only upon the right-hand roadway and no vehicle shall be driven over, across, or within any such dividing space, barrier, or section, except through an opening in such physical barrier or dividing section or space or at a crossover or intersection established by public authority.
