unless it’s a holiday (like Thanksgiving or Christmas level) getting from Fall River to Boston at 7am is probably a 2 hour drive minimum. Around 6am the traffic starts around the Bridgewater area on 24N it loosens up a little up by Avon then can be complete gridlock until you get to the Tip O’Neil tunnel. I would definitely recommend the train, she would probably need to go to Middleboro to catch the train or Bridgewater… I don’t think the CR is running further south yet.
