A D.C. appeals court threw out one driver's $100 speed-camera ticket because the camera's 1 mph margin of error left his true speed below the line — and a law firm is now asking whether the same math could help thousands of other ticketed drivers.
Investigation Only · No Class Action Filed
This article describes a real court ruling in one driver's individual traffic case and a law firm's investigation into possible broader claims. As of July 2026 no class action has been filed over the margin-of-error issue, no class has been certified, there is no settlement, and there is nothing to claim or file. This page is general information, not legal advice.
What Is This About?
A Washington, D.C. driver named in court papers as the appellant fought a single automated speed-camera ticket all the way to the District's highest court — and won. In Ricciardi v. District of Columbia, No. 24-CV-0718, the D.C. Court of Appeals reversed a lower ruling and ordered the $100 ticket dismissed. The decision, issued in May 2026, turned on a narrow but powerful point: a camera reading that carries a margin of error cannot, by itself, prove a driver's exact speed.The ruling has drawn attention well beyond one ticket. Because it rests on how D.C.'s speed cameras measure speed — and how much proof the District must offer to sustain a ticket — a local class-action firm has opened an investigation into whether other drivers were ticketed on the same shaky footing. Important to be clear up front: that is an investigation, not a filed lawsuit. The court did not strike down D.C.'s camera program, did not order refunds, and did not create any class or claims process.
How One Driver Beat a $100 Ticket
The facts were simple. An automated camera recorded the driver's vehicle at 61 mph in a 50 mph zone and the District issued a $100 ticket for driving 11 to 15 mph over the limit — a band that, for a 50 mph zone, starts at exactly 61 mph. The catch is that D.C.'s speed cameras are treated as accurate within a margin of plus or minus 1 mph. A reading of 61, then, means the vehicle's true speed was somewhere between 60 and 62 mph.That one-mile band straddles the line. If the real speed was 60, there was no violation in that ticket band at all. As the Court of Appeals put it, the evidence showed only that the driver "was traveling between 60 and 62 mph, making it just as likely that he was traveling beneath the 61 mph threshold as above it." When the proof is a coin flip, the District loses — because it carries the burden.
What the Court Actually Ruled — and What It Did Not
To sustain a traffic infraction in D.C., the District must prove its case by "clear and convincing evidence," a demanding standard well above a simple more-likely-than-not tipping point. The court held that a camera reading sitting right at the edge of a citation band, once the margin of error is applied, does not clear that bar. It reversed the decision below and sent the case back with instructions to dismiss the notice of infraction.The court also rejected the District's reading of its own regulation. The District had argued, in effect, that a camera measuring within its 1 mph margin should be treated as perfectly accurate. The court disagreed, explaining that the regulation says only that a camera is "calibrated correctly and in proper working order" so long as it measures within that range — meaning the device is fit to deploy and issue tickets, not that its reading is conclusive proof of the exact speed.
Here is what the ruling did not do. It did not find the camera broken. It did not declare D.C.'s automated-enforcement program illegal. It did not order the District to refund anyone. And it did not certify a class or open any claims process. It decided one ticket, on its facts, and the cameras remain in operation.
Could This Become a Class Action?
That is the open question the ruling has set off — and, for now, it is only a question. Within about a week of the decision, the Washington, D.C. class-action firm Migliaccio & Rathod LLP announced a "D.C. Traffic Camera Ticket Practices Investigation," inviting drivers to come forward if they were ticketed for going exactly 11 mph over despite the 1 mph margin, hit with doubled fines for late payment, or caught by stop-sign cameras that generated multiple tickets before the first notice even arrived. Local television station NBC4 Washington reported that the ruling "could trigger a class action lawsuit," quoting an attorney who said he had started looking into whether there is "a universe of drivers" in the same position.None of that is a filed case. An investigation is a firm gathering information and potential claimants to decide whether a lawsuit is viable; it does not mean a class action exists, that a court has agreed with the theory beyond the one ticket in Ricciardi, or that any money will ever change hands. We will update this page if and when an actual complaint is filed.
Who Could Be Affected?
The drivers most directly in the ruling's path are those ticketed at the very bottom of a citation band — the classic "exactly 11 over" reading — where the margin of error can push the true speed below the threshold. On NBC4, an attorney characterized the "11 to 15 over" category as roughly 1.9 million tickets a year out of about 3.5 million total D.C. camera tickets annually; those are an on-air estimate, not an official DMV figure, but they give a sense of the potential scale. Whether a broader group of drivers has any collective remedy is exactly what the investigation aims to test. No class has been certified, and being in that category does not by itself entitle anyone to anything.What Can D.C. Drivers Do Now?
There is nothing to file and no refund to claim. What the ruling does give drivers is an argument. If you have an open, unpaid D.C. speed-camera ticket — particularly one issued at the low edge of a band, where the 1 mph margin could put your true speed below the cited threshold — you can point to the decision when you contest it through traffic adjudication. That is a defense to a live ticket, decided case by case; it is not an automatic dismissal, and it does not reach back to tickets you have already paid.If you have already paid a ticket, whether that money can ever be recovered is unresolved and is one of the things the law-firm investigation is examining.

A Separate, Older D.C. Camera Case — Don't Confuse Them
The Ricciardi margin-of-error ruling is distinct from an earlier, unrelated D.C. camera dispute that sometimes appears in the same news coverage. A 2020 class action, Matthews v. District of Columbia, challenged a single high-revenue speed camera on Interstate 295, arguing the District improperly lowered the limit through a work zone that allegedly did not exist and doubled fines as a result. That case rests on a different theory — improper work-zone signage and fines, not the accuracy margin — and predates the Ricciardi decision by years. The two should not be treated as the same case.Frequently Asked Questions
What did the DC speed camera ruling actually decide?
In Ricciardi v. District of Columbia, the D.C. Court of Appeals reversed a lower ruling and ordered a single $100 speed-camera ticket dismissed. The driver was recorded at 61 mph in a 50 mph zone, but D.C.'s cameras carry a plus-or-minus 1 mph margin of error, so the true speed was somewhere between 60 and 62 mph. Because the ticket threshold began at 61 mph, the court held the District had not proven by clear and convincing evidence that the driver was actually at or above 61. The ruling decided one man's ticket on its facts. It did not strike down the speed-camera program, order any refunds, or certify any class.
Is there a class action lawsuit over DC speed camera tickets?
Not yet. As of July 2026 no class action has been filed over the margin-of-error issue. A D.C. class-action firm has opened an investigation and is asking affected drivers to come forward, and local news has reported that the ruling could prompt a class action. An investigation is not a lawsuit, no class has been certified, and there is nothing to file or claim at this time.
Can I get a refund on a DC speed camera ticket I already paid?
There is no refund program. The ruling did not order the District to return money to anyone, and whether already-paid tickets can be recovered is an open question that the law-firm investigation is examining. There is no mechanism to claim a refund right now.
How can I use the ruling to fight a DC speed camera ticket?
The ruling is most relevant to an open, unpaid ticket, especially one issued at the very bottom of a citation band, such as a reading exactly at the threshold where the plus-or-minus 1 mph margin could put the true speed below the line. A driver contesting such a ticket can point to the decision to argue the District cannot meet its clear-and-convincing burden. It is not an automatic win, each case is decided on its own facts through traffic adjudication, and it does not apply to tickets you have already paid. If you want legal advice, consult an attorney licensed in D.C.
Does the ruling mean DC speed cameras are inaccurate or illegal?
No. The court did not find the camera defective or the program unlawful. It held only that a camera reading within a plus-or-minus 1 mph margin proves the speed falls within a range, not that the exact number is infallible. Where that range straddles the ticket threshold, the District may not be able to prove the violation to the required standard. The cameras remain in operation.
