Massive pileup in Michigan blamed on bad weather

"DETROIT – Michigan officials on Friday briefly evacuated the area of a fatal pileup of 150 vehicles on an icy interstate, including a trailer transporting formic acid and another one carrying fireworks, which both caught on fire.

A three-mile area around the crash in southern Michigan, about 10 miles east of Kalamazoo, was ordered evacuated out of caution because formic acid is a hazardous material, state police said.

But it was lifted because the formic acid had burned off, Michigan State Police spokesman Lt. Rick Pazder told Reuters.

Icy conditions and low visibility contributed to the crash that happened some 10 miles east of Kalamazoo on Interstate 94, near the border of Kalamazoo and Calhoun Counties."
