Cal. Code Regs. tit. 21, § 2110
(a) General requirements and responsibilities:
(b) Installation and maintenance. The Department shall be solely responsible at its discretion for furnishing, installing, and maintaining all Specific Informational Panels and Supplemental Directional Panels.
Each Qualified Motorist Service Business upon notification of approval of its application shall arrange to have its individual Business Sign fabricated.
The Department shall be solely responsible for the installation and removal of all Business Signs fastened to Motorist Services Informational Panels. Under no circumstances will anyone other than employees of the Department or the Department's contractors and agents be permitted to enter within the highway right-of-way for the installation, maintenance, or removal of any panel or sign.
The Department shall not be responsible for lost, stolen, defaced, deteriorated, damaged, or destroyed business signs regardless of the cause. The applicant shall be responsible for delivering to the location designated by the Department a replacement or renovated sign to the Department to replace any sign which is lost, stolen, defaced, damaged, or destroyed or which is in a deteriorated condition.
(c) Specifications. Each Business Sign placed on a Specific Informational Panel shall be 48 inches wide by 36 inches high. Each Business Sign placed on a Supplemental Directional Panel shall be 18 inches wide by 12 inches high. It is required that a single aluminum sheet of 0.050 inches, or thicker, be used for each business sign.
It is intended that when symbols, logos, or trademarks are used, they cover as much of the rectangular area as possible, consistent with their design.
The messages, background, and borders on all Business Signs shall be fully reflectorized. The signs for a Specific Informational Panel shall have a three-quarter ( ¾ ) inch white border and the signs for a Supplemental Directional Panel shall have a three-eights ( ⅜ ) inch white border, except that when commercial symbols, logos, or trademarks are used, the border may be omitted. They shall have only the full business name shown on the business license and the application/permit as a white, reflectorized message on a blue background except that business signs composed of nationally, regionally, or locally known commercial symbols, logos, or trademarks shall be used when applicable. If a commercial symbol, logo, or trademark is available and it does not contain any word, symbol, or trademark which the Department determines to be offensive to good taste and decency or misinformative to the traveling public, it shall be used in preference to any other form of business identification and shall be reproduced with the colors, general shape, and design consistent with customary use and with any On-Site Signs. Any integral legend shall be proportional to the size customarily used on a said symbol, logo, or trademark. Regardless of whether a symbol, logo, or trademark or the name of the business is used, the display shall be centered both vertically and horizontally on the Business Sign.
The principal legend on all Business Signs should be at least 10 inches in height on signs to be fastened on the Specific Informational Panels and at least four (4) inches in height on signs to be fastened on the Supplemental Directional Panels.
