How to Fight a Speed Camera Ticket in Marshalltown, IA (2026)
Marshalltown operates Iowa's smallest surviving fixed-camera ATE program: a single fixed speed camera at the 1600 block of Lincoln Way, eastbound, operated by vendor Sensys Gatso ('Gatso'). Marshalltown submitted 9 camera locations to the Iowa DOT and received a permit for only 1 — an 89% denial rate. The 2 fixed camera applications at S 12th Avenue were denied ('not least restrictive means' for SB; 'not necessary' for NB). The 6 mobile applications were denied as 'not using system prior to 1/1/2024' (Marshalltown attempted to add new mobile capacity but lacked pre-January-2024 operating history at those locations). Marshalltown launched its camera program in spring 2023 with vendor Gatso performing initial video review; Marshalltown Police officers conduct a second review before any citation is issued. Iowa Code Chapter 321P does not authorize red-light cameras in Iowa.

Step 1 — Confirm the citation location is the 1600 Block Lincoln Way (EB) — the only location with a valid Iowa DOT permit as of October 1, 2024. If the citation lists any other Marshalltown location (including S 12th Avenue NB or SB, E Olive Street, W Olive Street, E South Street, Marion Street, W Main Street, or E Southridge Road) and the violation date is on or after October 1, 2024, route immediately to the Iowa ia-no-dot-permit defense under §321P.6(3). Step 2 — Review the enforcement photograph (Iowa Code §321P.9(2) rear-only requirement). Step 3 — Contest per the instructions on your citation; use the Marshall County District Court address (17 East Main Street, Marshalltown, IA 50158) if district court is the applicable forum. Iowa Code §321P.7(2)(a) gives you the statutory right to submit evidence that you were not the driver. Step 4 — All six Iowa defenses from the Iowa state page apply, including the calibration defense (Gatso performs monthly calibrations; records are public under Iowa Code §321P.2(2)(a) and Chapter 22).

Who operates Marshalltown's speed camera and how does it work?

How do I know if my Marshalltown speed camera ticket is from a valid location?
Only the 1600 Block Lincoln Way (EB) fixed camera holds a valid Iowa DOT permit as of October 1, 2024. If your citation lists 2400 Block S 12th Avenue (NB or SB), or any of the six Olive Street, South Street, Marion Street, West Main Street, or Southridge Road mobile positions — and the violation date is on or after October 1, 2024 — the citation was issued without a valid DOT permit and may be void under Iowa Code §321P.6(3).
How do I contest a Marshalltown speed camera ticket?
