Airport vehicular traffic signs conform to the standards set by the:

• A. Federal Motor Vehicle Code
• B. Los Angeles Municipal Code
• C. International Traffic Sign Code
• D. California Vehicle Code, i.e., Stop, Yield, etc. In addition, special signs may be posted to alert drivers to special conditions.

Answer: (D)

Signs on airport roadways are governed by the California Vehicle Code because it defines the standard signs—like Stop and Yield—and the actions drivers must take. The federal rules focus on vehicle safety standards rather than everyday traffic signs, and international sign codes aren’t used in the U.S. City-specific codes apply to city streets, not internal airport roads. Airports can add signs for special conditions, but they operate within the California Vehicle Code framework.
