Police stopped a disqualified driver at Lismore on Saturday in a car carrying three drunk adults in the back and three children lying on a mattress.
The arrest was part of Operation Tortoise, targeting dangerous driving throughout the state.
The operation and holiday double-demerit period has now ended, with traffic on the Pacific Highway largely returning to normal.
The Transport Management Centre reports that traffic on the highway is back to pre-holiday conditions, with Ballina the last remaining pinch point to be removed from its system at 8.25pm last night.
Yesterday, traffic jams occurred at Ballina (up to 5km), Bulahdelah (around 10km), Tweed Heads (3km) and Hexham (2km).
