The Massachusetts Department of Transportation implemented a travel ban for large trucks on interstate highways for Saturday because of the severe winter weather forecast, according to a MassDOT tweet. The travel ban is in effect today from 6 a.m. through midnight “for tractor-trailer trucks, tandems and special permit haulers,” MassDOT said. “MassDOT urges all of these large truck drivers to plan accordingly and to stay off the roads to allow MassDOT crews to work,” the department said. During a Friday briefing, Gov. Charlie Baker urged all residents across the state “to avoid nonessential travel” ahead of the winter storm. “We are actively monitoring this weekend’s winter storm, and we are urging residents to stay home and to allow crews to safely treat and clear roadways,” Baker said. “MassDOT has 2561 pieces of equipment currently deployed statewide in snow & ice operations,” a tweet said.
