Cal. Code Regs. tit. 8, § 1590
(a) Private Roadways and Off-Highway Conditions.
(2) On private roads used for two-way traffic, arrangements shall be such that vehicles travel on the right side as much as possible. Signs shall be posted to clearly indicate variations from this system. Where practicable, separate haulage roads shall be provided between loaded and empty units. Haulage roads shall be wide enough to allow for safe passage. Safe distances between moving units shall be maintained.
Note: Left hand traffic patterns are permitted provided that vehicle operators are advised of the pattern and job site conditions warrant that the procedure is safe.
(4) Where a hazard exists to employees because of traffic or haulage conditions, a system of traffic controls shall be required so as to abate the hazard. (See Section 1598(b)).
Note: Nothing in this subsection shall preclude the use of additional signs that are not included in the Manual referenced in Section 1598(b). Examples: “Haul Road,” “Left Hand Pattern,” “Scraper Crossing,” etc.
(c) Equipment Control.
