BOSTON (CBS) – Gov. Deval Patrick declared a state of emergency in Massachusetts Friday afternoon for the blizzard that could bring up to 3 feet of snow.

He also announced he has signed an executive order to ban all travel on all roads in the state starting at 4 p.m. Friday.

There are some exceptions to the ban, including emergency workers, those who work in hospitals and media, and others required to be at their jobs.

The governor said rapid snowfall of 2-3 inches per hour will make for, “extremely dangerous conditions,” and will “make safe travel nearly impossible.”

This is the first time that a Massachusetts governor has issued an executive order like this since the Blizzard of 1978.

But back then it was put in place after the storm.

Patrick did not say when this ban would be lifted.

If you don’t have an exemption and you’re caught on the road, the penalty could be as steep as a $500 fine or, at worst, a year in jail.

At a news conference at the MEMA bunker in Framingham, Patrick told reporters it’s not about the punishment, they simply need the roads clear during the blizzard.

“Essentially we want everyone off the road,” MEMA spokesman Peter Judge told WBZ-TV’s Jon Keller. “We’re talking common sense here.”

Public transportation will not be an option either. The MBTA is shutting down at 3:30 p.m.

Here is the full text of Governor Patrick’s executive order:
