(A) When the streets in question are appropriately sign-posted no vehicle of any kind or nature whatsoever (other than passenger buses) shall be operated or moved upon or over any of the streets hereinafter in Section 10.28.030 designated without a permit as provided in this section, when the total weight of vehicle and load exceeds four and one-half tons.

(B) This section shall not apply to, and shall not prohibit any commercial vehicle as defined by the California Vehicle Code having a loaded weight in excess of the limit prescribed in this chapter from using any such streets by direct route from a street the use of which is not restricted as to such vehicles for the purpose of delivering or loading for transportation goods, warns or merchandise without such permit.

(C) The traffic engineer may, by written permit, authorize the operation of a vehicle or vehicles upon any of the streets hereinafter in Section 10.28.030 set forth, when the total weight of such vehicle or vehicles exceeds the maximum weight prescribed in this section, if, in the judgment of the traffic engineer, streets upon which such vehicle is to be operated can safely withstand the additional weight for a limited operation. Such permit shall be granted upon such conditions and upon depositing such bond as the traffic engineer, may, in his discretion, require.
