(A) All commercial vehicles exceeding 5,000 pounds in gross weight shall be restricted at all times to those streets specified by resolution; provided, however, that such vehicles may be operated thereon for the purpose of delivering or picking up materials or merchandise and then only by entering such street at the intersection nearest the destination of the vehicle and proceeding thereon no further than the nearest intersection thereafter. The provisions of this section do not apply to local public passenger bus operations.
(B) Except on state highways or state-controlled highways, it shall be unlawful for any commercial vehicle with a gross weight in excess of 10,000 pounds to be operated in any residence district between the hours of 5:30 p.m. and 7:00 a.m.; provided, however, that, in the event that these restrictions result in an undue hardship or unfair competition, the Board of Public Works and Safety 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 individuals.
