In MA you can get special electric vehicle plates. The plates are a no additional cost option when registering the car and is available for pure electrics or hybrids. My dealer did not get EV plates so I just got them for the cost and aggravation of plate swapping at the DMV. As far as I know it does not give you any privileges whatsoever, the idea is that emergency personel will know immediately they are dealing with an EV and not an ICE car and can proceed appropriately.
A cool number too specially since 5 is our lucky number
