Company logos or symbols shall be at least how many inches in diameter when not accompanied by approved lettering?

The requirement for company logos or symbols to be at least 18 inches in diameter when not accompanied by approved lettering ensures clear visibility and recognition. Adequate size allows for easy identification from a distance, which is particularly important in restricted areas such as at LAX where security and quick recognition of vehicles are critical.

Logos and symbols that are too small may not be discernible, leading to confusion and potential security risks. Thus, establishing a minimum size like 18 inches balances visibility needs with operational efficiency without creating unnecessary visual clutter. This standard helps maintain an orderly environment while ensuring that authorized personnel can quickly identify vehicles or equipment associated with specific companies.
