‘How long do I have to sue in Massachuetts for injuries from a car accident?’
Generally, you have three years from the date of the accident to bring a lawsuit in Massachusetts for injuries sustained in an auto accident. There are exceptions however, such as a two year statute of limitations for claims stemming from accidents involving MBTA vehicles.
Also, if you live in Massachusetts and your auto accident was in a different state, then that state's laws apply. Not all states have a three year statute of limitations like Massachusetts does.
