In Massachusetts, the “Right Turn on Red” rule allows drivers to make a right turn at a red light after coming to a complete stop, provided there is no sign explicitly prohibiting the maneuver. However, the rule has nuances and local variations that are important to understand, particularly in light of recent updates and municipal decisions.
Statewide Rule
Under Massachusetts General Laws, Section 8 of Chapter 89, drivers facing a steady red signal may turn right after stopping at the intersection, as long as they yield to pedestrians and other traffic proceeding as directed by the signal. This rule applies unless a sign is posted prohibiting such turns. Municipalities and state highway authorities have the authority to restrict right turns on red at specific intersections by installing “No Turn on Red” signs.
Local Variations
While the statewide rule permits right turns on red by default, cities and towns can impose stricter regulations. For example:
- Cambridge: In May 2024, Cambridge banned all right turns on red at every intersection in the city as part of its “Vision Zero” plan to enhance pedestrian and cyclist safety. Previously, this restriction applied to 80% of intersections in Cambridge, but additional signage was installed to extend the ban citywide.
- Boston: The City of Boston’s traffic regulations specify that drivers must obey all traffic control devices, including signs prohibiting right turns on red. These restrictions are implemented at intersections where safety concerns for pedestrians or traffic flow warrant such measures.
Reasons for Restrictions
The decision to prohibit right turns on red often stems from safety concerns. Studies have shown that allowing right turns on red increases risks for pedestrians and cyclists because drivers tend to focus on gaps in vehicular traffic rather than checking for pedestrians crossing the street. Sightline issues and traffic flow considerations also play a role in determining whether a “No Turn on Red” sign is necessary at a particular intersection.
Exceptions
Massachusetts law prohibits turning right on a steady red arrow signal unless another signal explicitly permits it. This distinction is important as some drivers mistakenly treat red arrows as equivalent to circular red signals when making right turns.
Historical Context
Massachusetts was the last state in the U.S. to legalize right turns on red in 1980, following federal pressure during the 1970s energy crisis. Even then, about 90% of intersections were equipped with “No Turn on Red” signs due to safety concerns. Today, local authorities retain significant discretion over where such turns are allowed.
While Massachusetts generally permits right turns on red, local municipalities like Cambridge have begun implementing stricter bans to prioritize pedestrian safety. Drivers should remain vigilant for “No Turn on Red” signs and familiarize themselves with specific rules in their area to avoid violations.
