At 11:45 a.m., on January 10, 1984, a G & D Auto Sales, Inc., tow truck was turning right from the company's driveway onto westbound State Route 44 in Rehoboth, Massachusetts when the rear-facing passenger car in tow, a 1981 Oldsmobile, was struck by an eastbound tractor-semitrailer operated by Branch Express Company. The 76,950-pound tractor-semitrailer continued eastbound; crossed the centerline of the damp, two-lane, two-way roadway; and struck the left front of a westbound Town of Rehoboth schoolbus carrying 15 students, ages 5 and 6. The 1979 schoolbus overturned and came to rest on its roof off the roadway. The driver of the schoolbus, and one student were killed; 12 students were injured. The driver of the tow truck was not injured.
