As snow began to accumulate Sunday morning, the Massachusetts Department of Transportation lowered the speed limit on the Massachusetts Turnpike in the Berkshires and Western Massachusetts.

The speed limit was lowered to 40 miles per hour in both eastbound and westbound lanes from the New York State line to mile marker 59 in Ludlow, according to the MassDOT post on social media.

In addition, trucks with tandem trailers and those with special permits were also barred from that section of the turnpike.

In a separate post, MassDOT said it had 1,671 pieces of equipment patrolling, spreading, and plowing. All districts have entered snow and ice operations.
