How to Fight a Red-Light Camera Ticket in Maryland (2026)

Both statutes expressly recognize this defense. Under §21-202.1(g)(1)(iv), the District Court may consider 'evidence that the person named in the citation was not operating the vehicle at the time of the violation.' Under §21-809(f)(1)(ii), the same defense applies. For speed camera citations, the owner must provide the court a letter, sworn to or affirmed and mailed by certified mail, return receipt requested. For RLC citations, the owner must provide the name and current address of the actual driver.

Both statutes expressly recognize the stolen-vehicle/plates defense. Under §21-202.1(g)(1)(ii), the District Court may consider that the motor vehicle or registration plates were stolen before the violation and were not under the owner's control. Under §21-809(f)(1)(i), the identical defense applies. The owner must prove this by submitting proof that a police report was filed about the stolen vehicle or plates 'in a timely manner.' The report must predate the violation.

Maryland Transportation Art. §21-202.1(b)(1) requires the agency to ensure the yellow interval is set in accordance with regulations adopted by the State Highway Administration consistent with FHWA standards. §21-202.1(b)(2) expressly bars the agency from issuing a citation at a traffic control signal that does not comply with those timing requirements. This is a statutory prohibition on citation issuance, not a discretionary argument.

For speed cameras, §21-809(a)(3)(ii)(1) expressly defines 'a recorded image of a registration plate that does not match the registration plate issued for the motor vehicle in the recorded image' as an erroneous violation, triggering the mandatory administrative review and voiding obligation. For RLC, the same argument applies under the catchall defense in §21-202.1(g)(1)(v).

§21-809(a)(3)(ii)(1) (plate mismatch = erroneous violation, mandatory void on admin review); §21-202.1(g)(1)(v) (RLC catchall — any evidence the court deems pertinent); §21-809(b)(1)(x)(2)(B) (administrator must void erroneous violations). Source: mgaleg.maryland.gov

Maryland Transportation Art. §21-202.1(g)(1)(iii) expressly permits the District Court to consider the defense 'that under §21-201 of this subtitle, this section is unenforceable against the owner because at the time and place of the alleged violation, the traffic control signal was not in proper position and legible enough to be seen by an ordinarily observant individual.' This is an express statutory defense codified directly in the red-light camera enforcement statute.
