In Massachusetts insurance companies due take into account the 3 Quarters of the way rule. Basically if a vehicle is already 3 quarters of the way through the intersection the drive of that vehicle generally has a good argument against fault. Typically if an individual is hit in the rear section of their vehicle while traveling through an intersection.
The right of way rule applies when a vehicle is closely approaching the intersection and it would be hazardous or cause and accident to enter into the intersection, but if a driver having so yielded or stopped and no other vehicle is entering the intersection the driver may proceed and the drivers of all other vehicles approaching the intersection shall yield the right-of-way to the vehicle proceeding.
Insurance companies don't usually fight vigorously against moderate claims. I was smart and hired a lawyer
