California banned speed cameras for decades, then wrote the safeguards into the statute: no licence points, no facial recognition, no vendor paid per ticket. The 72 percent drop in speeding is self-measured.

California outlawed automated speed enforcement for decades. A 2023 state law let six cities try it, and San Francisco went first: warnings from March 2025, citations from 5 August 2025, at 33 locations capped by the statute itself. The law does the constraining — civil fines only, no licence points, no facial recognition, 50 to 80 percent discounts for low-income drivers, and no paying the vendor per ticket.

📊 Impact

SFMTA pneumatic-tube surveys report the share of drivers travelling 10 mph or more over the limit fell about 72 percent across 15 of the 33 sites after six months, and nearly 80 percent after one year. The agency says about 65 percent of drivers who received a warning or citation did not get a second one, and that the effect became less pronounced in autumn 2025. All figures are self-reported, measured at camera sites with no stated control group. No collision or injury outcome has been published; an 18-month evaluation is due in late 2026.

🎓 Lesson

The guardrails that usually get argued over in a procurement were written into the enabling statute instead: California bans paying the camera vendor per ticket or as a share of revenue, bans facial recognition, and ring-fences the money for street safety.

↗ SFMTA — Speed Safety Cameras (operator)Primary. Phase dates in the agency's own words: launch 20 March 2025, 'all cameras were issuing warnings as of June 6, 2025', and 'The program began issuing citations on August 5, 2025'. Also the fine schedule ($50 / $100 / $200 / $500 by speed band) and the two income-based reductions (50 percent low income, 80 percent for public-benefits recipients), plus the table of all 33 locations.

↗ SFMTA — one year in, speeding down 79 percent (operator)Sentence-level source for the headline figure — 'A nearly 80% drop in the share of drivers traveling 10 mph or more above the posted speed limit' — and for the recidivism claim, 'about two-thirds of drivers (65%) who have received a warning or citation did not get another one'. Also the statutory cap in the operator's own words ('Under AB 645, our program was limited to 33 locations') and the revenue rule ('the SFMTA may only use Speed Safety Camera Program fines for two things: covering program costs and funding street safety projects'). Notes the effect weakened in autumn 2025 and that an 18-month evaluation follows in the second half of 2026.

↗ SFMTA — initial evaluation, six months (operator)Sentence-level source for the six-month figure: 'On average, there was a 72% reduction in speeding vehicles across these 15 sample sites'. Establishes the method and its limits — pneumatic tube counts at 15 of the 33 sites, measured September 2025 against pre-activation baselines, with no control sites described. Also gives the monthly warning counts for June to August 2025.

↗ California Vehicle Code section 22425 (statute)The constraint that distinguishes this entry, quoted exactly: 'The contract shall not allow for payment or compensation based on the number of notices of violation issued, or as a percentage of revenue generated, from the use of the system' (subdivision n).

↗ California Legislature — AB 645, chaptered text (statute)Carries every other constraint the entry claims: 'the use of facial recognition technology in conjunction with a speed safety system shall be prohibited'; records 'shall be confidential' and not shared with other agencies except by court order; photographs not resulting in a violation destroyed within five business days; citation records kept at most three years; civil penalties with no violation point assessed and no licence suspension; siting limited to safety corridors, school zones and streets with a documented history of speed contests; a 60-day warning period; 80 percent and 50 percent income-based reductions; excess revenue to traffic calming within three years, then to the state Active Transportation Program; whole programme repealed 1 January 2032.

↗ Verra Mobility — contract award (vendor)Names the operator behind the SFMTA: Verra Mobility, formerly American Traffic Solutions, approved to design, build, operate and maintain the system at '33 sites across the city'. Supports the narrower version of the first claim — San Francisco was 'the first pilot city to complete its procurement process' under AB 645. The release discloses no contract duration or value, which is why no cost figure is carried.

↗ ABC7 San Francisco — first months of citations (press)Independent source for volume: 'they gave more than 16,555 citations that month or over 500 citations a day' in August 2025, a combined 260,142 warnings and citations from June to August, and 'Citations generated more than $600,000'. Later cumulative totals circulating in aggregator coverage were not carried, because the revenue figure quoted there collides with the reported vendor contract value.

↗ San Francisco Public Press — the equity objection (press)The counterweight, sourced rather than paraphrased: 'Human Rights Watch has criticized AB 645 for allowing cities to install more speed cameras in lower-income neighborhoods, so long as they are deemed high-risk areas', and the mechanism behind it — crashes cluster in the poorest districts, and 'the city labels nearly every street in the Tenderloin a high-injury corridor'. Also records the July 2026 proposal to expand from 33 locations to 80 or more.

↗ Cochrane systematic review — speed cameras (peer-reviewed, other jurisdictions)Context only, deliberately NOT attributed to San Francisco. Across 28 studies, crashes near camera sites fell 8 to 49 percent and fatal or serious injury crashes 11 to 44 percent, while the authors judged the evidence 'moderate quality at best' and declined to state an overall magnitude. Listed so readers can see what the international literature does and does not establish, since San Francisco has published no crash outcome of its own.
