Hazmat road accidents in the U.S. have more than doubled in the past decade

It was the costliest hazardous materials spill on a highway in Massachusetts in the past decade. 

It happened on a dry, clear, sunny day just after 2 o'clock in Revere Beach, just north of Boston, on April 17, 2020. 

A Department of Transportation report shows a tractor trailer hauling gasoline mixed with ethyl alcohol took a roundabout much too fast and flipped over. The crash spilled the big rig's entire load, nearly 10,000 gallons of liquid in all, onto Highway 1A and into a nearby saltwater marsh.
