California Codes, Business and Professions Code - BPC, Division 3 — Professions and Vocations Generally, Chapter 2 — Advertisers, Article 1 — General Provisions, Section 5216.3
“Main-traveled way” is the traveled way of a highway on which through traffic is carried. In the case of a divided highway, the traveled way of each of the separate roadways for traffic in opposite directions is a main-traveled way. Main-traveled way does not include facilities such as frontage roads, ramps, auxiliary lanes, parking areas, or shoulders.
Notes
Defines “main-traveled way” as the part of a highway carrying through traffic and, on divided highways, each separate roadway carrying traffic in opposite directions. The term excludes frontage roads, ramps, auxiliary lanes, parking areas, and shoulders, so those facilities are not part of the main-traveled way under this definition.
