You get 60 days to renew an expired Massachusetts driver’s licence after you return home from active duty. If you hold a licence issued by the U.S. Armed Forces in another country you can drive in Massachusetts for up to 45 days.
There is nothing to apply for. Renew your licence at a Registry of Motor Vehicles location within 60 days of returning, and carry your discharge paperwork in the meantime.
Your discharge paperwork showing your release date, and your expired Massachusetts licence.
