Added reparation benefits (or ARBs) coverage is additional no-fault benefits above and beyond the basic $10,000. The first $10,000 of no-fault benefits are known as basic reparation benefits (BRBs). You can buy added reparation benefits in units of $10,000 up to $40,000 or up to the amount of your liablity coverage over the minimum of $25,000, whichever is less. ARBs are a good way to provide full insurance for injuries covered by a car accident or wreck.
Remember that "no-fault" benefits are sometimes referred to as BRB (short for Basic Reparation Benefits) or PIP benefits (short for Personal Injury Protection benefits).
