Tucson, AZ Mobility & Curb Rules: Red-Light Cameras (2026)

Section 20-2 defines civil traffic violations for Chapter 20, but carries two paragraphs added by Proposition 201, approved at a special election on November 3, 2015: it is expressly not a violation if the evidence was gathered through automatic photo red light cameras or automatic photo speed cameras of the kind a private contractor operated for the city in 2012, and the city is barred from using or contracting for that technology, or any traffic-control technology that lacks a human, on-site eyewitness able to testify in court.

That second clause is broader than just cameras, it forecloses any automated enforcement system, present or future, that can't produce a live witness. The ban followed Tucson's earlier red-light and speed camera program, which the 2012 contractor reference points back to; Prop 201 was a citizen initiative that wrote the prohibition directly into the traffic code rather than leaving it to a council vote that could be reversed. The editor's note attached to § 20-2 confirms the amendment's origin as ballot Proposition No. 201. Because the ban sits inside the civil-violation definition itself, camera-based citations for red-light or speed violations are not just unenforceable in practice, the code affirmatively states they are not violations, cutting off any argument that a citation could survive court review.

General civil sanctions elsewhere in the chapter (up to $500 under § 20-3) apply only to violations proven the ordinary way, through an officer who can testify.
