Governor Deval Patrick D-Mass just announced that he had signed an executive order banning all vehicles on the highways after 4:00 p.m. in advance of a blizzard expected to hit the state this evening.

“Signed an Executive Order banning vehicles on the road effective at 4pm today,” the Governor warned on Twitter after explaining the ban during a press conference. Patrick said that there were exemptions for emergency vehicles and workers.

The last vehicle ban in Massachusetts was reportedly in 1978.

The penalty for breaking the ban is up to one year imprisonment and a $500 fine.
