In Massachusetts although the Registry of Motor Vehicles mails license renewal forms, you are obligated to renew your driver’s license before the expiration date and to inform the RMV and the U.S. Post Office of any address change.

According to the RMV your Massachusetts driver’s license is valid for 5 years unless it is your first license, which expires on your fifth birthday after the date of issue. You may renew your license up to 1 year before the expiration date. If your license expired more than 4 years ago, you may be required to take a written test and road test.

From the information we could find it appears that the penalty for driving with an expired license is a fine. To be certain though what your penalties will be, if you were ticketed for this law violation, check with the court listed on the citation or the RMV.
