What makes Arizona different
The instrument that actually resolves most Arizona citations is the Supreme Court Defensive Driving Program. One eligible civil citation can be dismissed every twelve months by completing an approved course — dismissed, not reduced, so no conviction is entered, no points are assessed, and nothing reaches the record for an insurer to find. For a routine citation it is usually a cleaner outcome than contesting.
The third thing worth knowing is that photo radar is a different animal. Arizona uses automated enforcement extensively, and a photo citation has to be served properly to be enforceable, which gives it a procedural life of its own that an officer-issued citation does not have.
