What is the minimum quantity of gasoline transported on a vehicle requiring hazardous material placards?

It's determined by weight. Gasoline is Hazard Class 3, which requires placards to be displayed if more than 1,000 lbs. of it is being transported. One gallon of petrol weighs between 5.8 and 6.5 lbs, so you'd be looking at 153 to gallons (roughly) before placards had to be displayed.
