Except on state highways or state-controlled highways it shall be unlawful for any person to operate a commercial vehicle with a gross weight in excess of 10,000 pounds in any residence district; provided, however, that this prohibition shall not apply to such a vehicle when it is making a delivery from a state or state-controlled highway and returning to it by the most direct route possible, and in the event that this restriction results in any undue hardship or unfair competition, the Chief of Police shall have the power to authorize the issuance of special permits from time to time as deemed necessary for the protection of the rights of any individual.
