Whenever the Board shall determine that the interests of the national defense or public safety require that any overload be moved at a time or in a manner not permitted by the express provisions of the article, it may endorse upon the permit an express exemption from any such particular provisions, which exemption shall be effective as to any overload moved under that permit. The Board may attach such conditions to any such exception as it may deem reasonable to be required for public safety or the protection of property, including a requirement of fair indemnity on behalf of the City, members of the public, or both. (Amended by Ord. No. 145,625, Eff. 4/6/74.)
