In Massachusetts, as of 2025, drivers are generally permitted to make a right turn at a red light after coming to a complete stop, unless otherwise indicated by signage. This rule is codified in state law and remains consistent with longstanding practice.
Key requirements:
- Complete Stop: You must come to a full stop at the red light, as close as practicable to the crosswalk or intersection entrance.
- Yielding: Before turning, you must yield the right-of-way to pedestrians and any other vehicles proceeding through the intersection as directed by the traffic signal.
- Signage: If a sign is posted stating “No Turn on Red,” you must obey the sign and are prohibited from making the turn.
- Left on Red: On a one-way street, you may also turn left onto another one-way street after stopping, unless prohibited by signage.
Local Authority to Restrict Right on Red
Cities and towns in Massachusetts have the authority to restrict right turns on red at specific intersections. These restrictions are implemented by posting clear “No Turn on Red” signs. The restriction is only enforceable when such signage is present.
Example:
- Cambridge: As of 2024, Cambridge has banned right turns on red at all signalized intersections, posting signs at every affected location as part of its Vision Zero safety initiative.
Common Reasons for Restrictions
Local officials may prohibit right turns on red for reasons including:
- Pedestrian Safety: High foot traffic areas where drivers may overlook crossing pedestrians.
- Traffic Flow: To prevent traffic from backing up into intersections or to coordinate with nearby signals.
- Limited Visibility: Poor sight lines making it unsafe to turn on red.
Penalties for Violations
If you turn right on red where it is prohibited by signage, you may be fined not less than $35.
Summary Table: Right Turn on Red in Massachusetts (2025)

Massachusetts allows right turns on red after a complete stop and yielding, except where signs prohibit it.
Local jurisdictions can—and do—enact stricter rules, so always look for posted signs, especially in cities like Cambridge where right on red is banned at all signals. Violating these rules can result in fines and enforcement is ongoing.
