My question involves an injury-based situation that occurred in the state of: MA.

If driving on a four-lane highway that is without a barrier, but is facing heavy traffic, it is not uncommon that there will be a school bus coming in the opposite direction. If you stop as the school bus stops three lanes away, as the law requires, but are about to be rear-ended by a car that doesn't see the school bus(the school buses can be incredibly difficult to see across a four lane highway that's lacking a barrier,) are you legally required to absorb the hit of the car behind you, or is accident evasion a defense to passing a school bus that's three lanes away in the opposite direction?
