Mom can't drive anymore and needs to convert their license to a state ID License was just renewed 2 years ago Any advice on what she needs to do?

Surrender her license and obtain a RI state ID.

We can switch her license over to an ID. You can do that at any DMV office. You may also consider whether to apply at that time for a handicapped placard you can use when driving her to doctor's appointments, etc. That form is here: http://www.dmv.ri.gov/documents/forms/disability/DisabilityParkingPlacard.pdf

Surrender license at dmv and get a State ID
