California Codes, Business and Professions Code - BPC, Division 3 — Professions and Vocations Generally, Chapter 2 — Advertisers, Article 1 — General Provisions, Section 5222
“660 feet from the edge of the right-of-way” means 660 feet measured from the edge of the right-of-way horizontally along a line normal or perpendicular to the centerline of the highway.
Notes
Defines 660 feet from the edge of the right-of-way as a horizontal measurement starting at that edge and running along a line normal or perpendicular to the highway centerline. The statutory distance is therefore measured perpendicular to the centerline rather than along the highway.
