Massachusetts License Plate Display Law — 2025 Guide
Massachusetts has unique mounting rules — drivers must display all plates issued to them.
The Law at a Glance
Recent Changes
Massachusetts is unique: drivers must display ALL plates issued. Pre-1986 green-on-white commercial plates were single-rear-only; current 'Spirit of America' base requires both. About 900,000 drivers still had green-on-white plates in 2017.
State-Specific Notes
Massachusetts is a conditional two-plate state based on the plate base type.
