In no case shall there be a lapse in the loading or unloading of materials in excess of thirty (30) minutes except when so marked by appropriate signs. This permitted lapse in loading and unloading operations is for the sole purpose of accumulating loads, signing of material receipts and incidental necessary activities.

The above exceptions do not permit double parking.
