The Vermont Truck & Bus Association reminds carriers traveling on U.S. Route 4 in the state from the New Hampshire line to Vermont Route 100 that a state permit is required for combinations between 68 and 75 feet in length.  The permit is free from the state department of motor vehicles, but being caught without one will be expensive.  VTBA warns that Woodstock, Vermont, is particularly aggressive about enforcing this requirement.  See here:  http://dmv.vermont.gov/sites/dmv/files/documents/OSD-01-Excess_Length_App.pdf.
