Whenever traffic is controlled by pavement markings, such markings shall be white in color.
When a broken line is used for a center or lane line, such a line is a guideline and may not be crossed by vehicular traffic, unless such movement can be made with safety.
When traffic cones are used by proper authority to temporarily control the flow of traffic in lanes other than designated by the permanent pavement markings, the lines designated by the cones shall have the same regulatory effect as the permanent markings.
