(3) Carrier Name. The name of the motor carrier operating the school bus shall be displayed below the windows on both sides of the bus in letters not less than 4 inches nor more than 6 inches in height. As an alternative, a sign showing the name of the school in letters 4 to 6 inches in height and the name of the district or contractor 2 to 6 inches in height is permitted. Carrier names or lettering styles which constitute a registered trademark may include a registered trademark symbol displayed in close proximity to the carrier name. Addresses, telephone numbers, stripes, slogans, or graphic designs other than the lettering style of the carrier name shall not be considered part of the carrier name and are prohibited. Extremely ornate lettering styles which substantially reduce the legibility of the required sign from a distance of 50 feet shall not be used.
(4) Bus Number. The bus number assigned by the company or school shall be displayed in characters at least 4 inches in height in one of the following manners:
(A) On all four corners of the bus body.

The carrier identification number assigned by the department shall be displayed in characters two inches in height on both sides of the bus, centered not less than two inches nor more than 24 inches below the carrier name. The display shall consist of the letters CA followed by the digits assigned to the carrier. A space may be inserted between the letters CA and the digits.
(A) School buses may display the carrier's valid operating authority or identification number assigned by the Interstate Commerce Commission, the California Public Utilities Commission, or the United States Department of Transportation, in the manner specified above for carrier identification numbers, instead of the carrier identification number assigned by the department.
(B) Carrier identification numbers assigned by the department or identification numbers assigned by the Public Utilities Commission and displayed on school buses prior to September 1, 1989, may continue to be displayed irrespective of the size and location requirements of subsection (b)(5) of this section.
(6) Emergency Exit. A sign reading "EMERGENCY EXIT" in upper case letters 2 inches in height shall be on the exterior of the bus on or above each emergency exit. Exterior emergency exit signs may have a white background if located above the emergency exit in the white area of school buses with white roofs. A sign reading "EMERGENCY EXIT" in upper case letters at least 2 inches in height shall be on the interior of the bus on or above each emergency exit.

Interior emergency exit signs may be backlighted if no glaring light is projected into the driver's eyes either directly or by reflection from any surface forward or to either side of the driver.
(A) For exterior or interior emergency exit signs, the words "EMERGENCY DOOR" in upper case letters may be used to identify floor-level emergency doors instead of the words "EMERGENCY EXIT".
(B) Roof emergency exits shall be identified as described in subsection (b)(6) for other emergency exits, except that emergency exit signs for roof exits need not meet the size and color requirements of that subsection if they are clearly identified as emergency exits on the interior and exterior of the emergency exit assembly as supplied by its manufacturer.
(C) School buses manufactured prior to January 1, 1992 may have emergency exit signs applied as decals on the window glass of the emergency exit. If this option is exercised, the emergency exit decals shall meet the size and wording requirements of this subsection, but need not meet the color requirements.
(7) Stop Signal Arm. School buses manufactured on or after September 1, 1992, shall be equipped with at least one stop signal arm.
