A tanker endorsement candidate has thoroughly studied Section 8 but skips Section 9 (Hazardous Materials) because they don't plan to haul placarded loads. Is skipping Section 9 consistent with the CDL manual's own study guidance?

AAMVA CDL Manual, Section 8 introduction (p. 8-8-1)

Many liquids hauled in bulk tankers, such as fuels and chemicals, are themselves regulated as hazardous materials, so hazmat concepts like placarding and shipping papers can surface on tanker-related questions even for a driver who thinks they are only hauling non-hazmat product.
