The first steps of this lesson
Step 1: The Five Curb Colors
The 2026 California MUTCD, Section 3B.18, quotes California Vehicle Code (CVC) Section 21458: red indicates no stopping, standing or parking whether the vehicle is attended or unattended, except that a bus may stop in a red zone marked as a bus loading zone. Yellow indicates stopping only to load or unload passengers or freight for the time specified by local ordinance. White indicates loading or unloading of passengers, or depositing mail in an adjacent mailbox. Green indicates time limit parking, and blue indicates parking limited exclusively to the vehicles of disabled persons and disabled veterans.
Step 2: How Curb Markings Are Used
Section 3B.18 states that in California curb markings are not used to delineate traffic; they are mainly used for parking regulation, and parking regulations must be covered by ordinance or order of the authority having jurisdiction. Where curb markings are used without signs, the Guidance paragraph says a legible word marking such as "No Parking" should be placed on the curb. That section is written for streets and highways, so on a private lot follow the plans and what the fire code official requires. Section 3A.03 adds that blue markings supplement white markings for accessible parking spaces.
