How to Fight a Speed 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. §21-809(b)(4)(i) requires every speed monitoring system to undergo an annual calibration check by an independent laboratory. Under §21-809(a)(3)(ii)(6), a violation recorded by a speed monitoring system with an expired calibration certificate is expressly defined as an 'erroneous violation.' The program administrator must void an erroneous violation upon request (§21-809(b)(1)(x)(2)(B)).

MD Transportation Art. §21-809(a)(3)(ii)(6) (expired calibration = erroneous violation); §21-809(b)(4)(i)–(ii) (annual calibration + certificate required); §21-809(b)(1)(x)(2)(B) (administrator must void erroneous violations).

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. §21-809(d)(4) requires that a speed camera citation 'shall be mailed no later than 2 weeks after the alleged violation if the vehicle is registered in this State, and 30 days after the alleged violation if the vehicle is registered in another state.' Late mailing is a procedural defect the court 'may consider' under the catchall in §21-809(f)(1)(iii).
