State police have assigned extra patrols over the Thanksgiving weekend in an effort to combat drunken and aggressive driving.

From midnight on Wednesday to 4:45 Thursday evening, state police made 723 arrests for speeding, 40 seat belt arrests and 1,431 arrests for moving violations that included using a cellphone while driving, making an unsafe lane change, failure to use a turn signal and following too close.
