Red light cameras in Massachusetts are not legal, and no city or town currently issues automated red light tickets. State law requires a police officer to personally observe or be informed of a violation and sign the citation, so a ticket generated by a camera and mailed to the registered owner has no legal footing here. Several bills would change that, but none has been enacted.
Why the Law Blocks Automated Red Light Tickets
The obstacle is Chapter 90C of the General Laws, which sets the procedure for every motor vehicle citation in the state. It requires a police officer to record the violation on a citation, sign it, and give the driver a copy.1General Court of Massachusetts. Massachusetts General Laws Chapter 90C Section 2 – Citations and Citation Books There is no alternative pathway for a computer system to produce a valid ticket on its own.
Section 3 reinforces the point. When an officer “observes or has brought to the officer’s attention” a civil motor vehicle infraction, the officer decides whether to warn or cite the driver.2General Court of Massachusetts. Massachusetts General Laws Chapter 90C Section 3 – Issuance of Citations That leaves room for someone to report a violation to an officer, but the officer still makes the call and issues the ticket personally. An automated system that photographs a car, reads the plate, and mails a fine to the owner has no place in that framework.
No statute explicitly bans red light cameras. The citation system was simply built around a human officer standing between an alleged violation and a penalty, and until the legislature creates a parallel process for camera enforcement, any camera-generated ticket would lack legal authority.
What the Cameras at Intersections Actually Do
The devices mounted near traffic signals are not watching for red light runners. Most are video detection sensors that help manage signal timing. Instead of relying on pressure plates buried under the road, they detect whether vehicles are waiting at an intersection and adjust the lights accordingly. When fewer cars are present on a side street, the main road stays green longer; when a queue builds, the sensor triggers a change sooner. The data is processed locally for traffic engineering.
Another device you may spot is an emergency vehicle preemption sensor, sometimes called Opticom after a common brand. These receivers detect signals from approaching ambulances and fire trucks and override the normal cycle to give emergency vehicles a green. The hardware is built to receive a specific optical or radio pulse and cannot photograph plates or drivers.
Neither system captures the high-resolution images of plates a red light camera program would require.
How Red Light Tickets Work in Massachusetts Today
Without cameras, red light enforcement depends on a police officer observing the violation or having it reported. If you are cited, you receive a traffic ticket under the standard Chapter 90C process.2General Court of Massachusetts. Massachusetts General Laws Chapter 90C Section 3 – Issuance of Citations Running a red light is a civil motor vehicle infraction with a scheduled fine. You can pay the fine, request a hearing at a district court, or appeal an unfavorable result.
Insurance consequences matter here. The Safe Driver Insurance Plan adjusts premiums based on your driving record, and a minor traffic violation adds two surcharge points that can increase premiums across four coverages, including bodily injury, personal injury protection, property damage, and collision. There is one meaningful break: your first minor traffic violation in a five-year window carries zero surcharge points, so a single red light ticket after years of clean driving would not affect your rates.3Massachusetts Registry of Motor Vehicles.

Legislation That Could Change This
Multiple bills in the current session would create a legal framework for automated enforcement. Senate Bill 2344 would let municipalities use both red light cameras and speed cameras, capping fines at $150 per violation.4General Court of Massachusetts. Massachusetts Senate Bill 2344 – An Act Relative to Traffic Regulation Using Road Safety Cameras House Bill 3660 takes a narrower approach, targeting speed cameras in highway work zones for drivers going 15 or more mph over the limit. House Bill 3905 would permit speed cameras in school zones in Salem.
Governor Healey’s fiscal year 2026 budget went further, proposing a new Chapter 90L called the Automated Road Safety Enforcement Program. Under that proposal, speed camera fines would follow a two-year lookback: a warning for the first offense, $25 for a second or later violation, and $100 if the driver was going 25 or more mph over the limit.5Massachusetts Governor’s Budget. Section 56 Speed Camera Enforcement
A common thread across these proposals is that camera-generated violations would stay off your driving record and would not trigger insurance surcharges. The Governor’s budget specifies that a speed camera violation would not count as a moving violation for Safe Driver Insurance Plan purposes.5Massachusetts Governor’s Budget. Section 56 Speed Camera Enforcement None of these bills has been enacted as of this writing.
The One Automated Exception: School Bus Stop-Arm Cameras
Massachusetts authorized one narrow form of automated camera enforcement in 2024: stop-arm cameras on school buses. These systems record vehicles that illegally pass a stopped school bus while its red lights are flashing.6National Conference of State Legislatures. State School Bus Stop-Arm Camera Laws Buses with the cameras must display signage, and a local officer reviews the footage before deciding whether to issue a citation to the registered owner.
The law treats these violations as non-criminal. A stop-arm camera ticket does not count as a moving violation, though it is noted on the owner’s driving record. Recordings that do not show a violation must be destroyed within 30 days, and footage tied to a violation must be destroyed within one year of the case’s final resolution. This program is structurally separate from any proposed red light camera system and applies only to passing a stopped school bus.
