Full Breakdown

The devices are restricted to rear-facing images only, the ordinance bars any "frontal view photograph" and any rear photo "above the bottom of the rear window", and at least one image must clearly show the plate. L. Chapter 90C, Sections 2 and 3. Mailing deadlines differ by registration: 14 days for Massachusetts-registered vehicles, 21 days for out-of-state vehicles, both exclusive of Sundays and holidays.

An owner may pay the scheduled assessment to close the case, or request a hearing before a District Court Clerk-Magistrate within 20 days by mailing back the citation with a signed request and, if disputing liability, a signed affidavit naming the actual operator and any witnesses. L. Chapter 90, Section 20E. " Nonpayment after 30 days lets the Registry withhold or suspend the owner's license or registration until the fine, assessment and late fees are paid.

Violations & Fines

A red-light violation captured by the system is a civil infraction, not a criminal offense, carrying the maximum scheduled assessment for the violation, which can rise up to 33% if left unpaid past 30 days. Registered owners who don't pay, don't appear for a requested hearing, or lose at hearing face non-renewal or suspension of their driver's license and vehicle registration by the Registry of Motor Vehicles.

Frequently Asked Questions

Is Boston's red-light camera fine a criminal charge?
No. Subsection 7-7.4(E)(3) states a penalty imposed for a violation "shall not be deemed a criminal conviction." It's a civil assessment against the registered owner of the vehicle, resolved through the Registry of Motor Vehicles and a District Court civil hearing process rather than a criminal court.
How long do I have to contest a Boston red-light camera ticket?
20 days from the mailing of the citation. You request a hearing by signing the back of the citation and mailing it to the registrar, or appearing in person; if you're disputing liability rather than just requesting a hearing, you must also submit a signed affidavit identifying the actual operator and any witnesses.
What happens if I don't pay a Boston red-light camera fine?
After 30 days from the mailing of the notice, the registrar can refuse to issue or renew, or can suspend, your license to drive and your vehicle registration until the fine, assessment and any late fees are paid in full, per Subsection 7-7.4(D)(8).
Can I be fined if someone else was driving my car?
You can dispute liability by submitting a signed affidavit within 20 days naming the actual operator and any supporting witnesses. The ordinance also exempts owners when the violation involved a rental or leased vehicle whose company complied with M.G.L. Chapter 90, Section 20E.
