You MUST NOT wait or park on yellow lines during the times of operation shown on nearby time plates (or zone entry signs if in a Controlled Parking Zone) - see pages 112 and 115. Double yellow lines indicate a prohibition of waiting at any time even if there are no upright signs. You MUST NOT wait or park, or stop to set down and pick up passengers, on school entrance markings (see page 116) when upright signs indicate a prohibition of stopping.
