Texas traffic — public records
Texas public records run on the Public Information Act (Tex. Gov't Code ch. 552 — text loaded in the corpus), not Florida's chapter 119. A records request is a letter to the governmental body, not a filing with the court. Here is what defendants commonly request and why; whether any of it helps your case is a legal judgment.
Radar/LIDAR calibration & maintenance logs
The device's certification and last-calibration records — commonly requested to test the speed reading.
Officer certification & training records
The issuing officer's device-operation certification.
Bodycam / dashcam footage (+ retention policy)
The stop on video; ask about retention so it is not overwritten (a preserve-pending request).
CAD / dispatch records
The computer-aided-dispatch log for the stop.
Signal-timing / sign work orders
For a signal or sign-based citation, the maintenance and timing records.
The complaint / charging instrument
The document that actually charges the offense in the justice/municipal court.
Read the Act itself: Gov't Code § 552.001 (the public-policy statement). A request does not stop any deadline — verify your dates with the court.
