The association and its leadership had to contend with a tidal wave of regulatory changes from the federal government, economic challenges, and more organizational changes designed to strengthen NTTC. Economic issues facing the tank truck sector included the steep drop in oil prices that idled drilling rigs across the United States. Tank truck fleets serving the oilfield suffered with the rest of the service sector.
