According to the Massachusetts Division of Insurance, the insurance regulatory body for MA, if any of your children who are household members obtain a driver's license you must notify your company within 60 days of that date.

In any state, it is typical that all household drivers are listed or excluded on your policy. You must list all licensed household members and any other licensed person who will customarily operate your auto according to the MA DOI.

Some insurance companies will require you to place your teen on the license when they have received their permit while others require you to do so when they have their full driver's license so speak with your insurance company's agent to see what your insurance provider requires you to do.
