Officers read plates and seals by eye at the kerb. The intelligence sits in the rule instead: how many digits you lose depends on your car's vintage class, and rises when an episode is declared.

Santiago rations driving by the last digit of the licence plate across the 32 comunas of the Provincia de Santiago plus San Bernardo and Puente Alto, weekdays 07:30 to 21:00 through the May-to-August pollution season. What is rationed is tiered rather than uniform. Catalytic cars carrying the sello verde and registered before 1 September 2011 lose two digits a day; older vehicles without the seal lose four and are barred outright from the Americo Vespucio ring; newer cars go free until an episode is declared. That declaration is the second layer: under the Gestion de Episodios Criticos, the environment ministry's Metropolitan secretariat works from the regional air-quality monitoring network and from separate MP10 and MP2.5 forecasting systems, and each step up to Alerta, Preemergencia or Emergencia adds digits to the ban. Enforcement rests on Carabineros, municipal inspectors and the transport ministry's inspection unit, backed by the region's camera network, which records licence plates; a violation costs 1 to 1.5 UTM. The CATI law lists the driving restriction among the infractions cameras may sanction automatically, and in August 2025 the transport minister expected it to take effect during 2026.

Live 📅 since 1992

📊 Impact

An independent peer-reviewed evaluation exploited the air-quality index thresholds that announce the warnings as instruments in a fuzzy regression discontinuity design and found the temporary bans reduce car trips by 6-9% during peak hours and by 7-8% off-peak, consistent with air pollution reductions during peak hours and with higher ridership on Santiago's mass-transit systems in hours when they run with excess capacity (Rivera, Journal of Environmental Economics and Management 108, 2021). No comparable evaluation of the permanent, non-episode restriction is cited here.

🎓 Lesson

Delhi's odd-even scheme is held back from this atlas because officers checked plates by eye and nothing else measured anything. Santiago clears the bar for a reason that has nothing to do with its cameras: the ration is set by a vehicle's vintage class and re-set by an air-quality reading, so the instrument sits in the rule, not in the enforcement.

Also the source for the Seremi de Transportes handling exemption authorisations.

🇨🇱 Critical Episode Management: A Next-Day Forecast With Legal Force · Santiago Its second layer: when the episode desk forecasts a bad day and declares an Alerta, more plate digits come off the road. 🇨🇴 Pico y Placa: Plate Rationing You Can Pay to Escape · Bogotá Both ration plates; Bogotá sells daily exemptions by vehicle value, Santiago hands them out by vintage — pre-2011 cars lose the most days. 🇮🇩 Ganjil-Genap: Jakarta's Odd-Even Plate Rationing · Jakarta Two peer-reviewed verdicts on one idea: Jakarta's camera-enforced ban changed nothing measurable; Santiago's cut car trips by 6-9%.

Ban half the cars: the licence-plate rationing family

Four cities that keep cars off the road by plate number — with four different enforcement designs and, until recently, almost no evidence that any of it cleans the air. The family's one robust rebound finding (drivers buying second cars) was measured in Mexico City and is imported everywhere else by analogy.

Hoy No Circula: Mexico City's Plate-Based Driving RestrictionMexico City, 🇲🇽 1989 Live Ongoing Peer-reviewed City government, Regional government not public A hologram from the compulsory emissions test decides who is exempt; peer-reviewed evaluations find no cleaner air — drivers bought second cars instead.
Restriccion Vehicular: Santiago's Vintage-Tiered Plate RationingSantiago, 🇨🇱 1992 Live Ongoing Peer-reviewed National government, Regional government not public Tiered by vehicle vintage with an air-quality trigger adding digits — and a peer-reviewed evaluation that actually finds fewer car trips at peak.
Number Coding: Metro Manila's Plate-Based Driving BanManila, 🇵🇭 1995 Live Ongoing Media Regional government, City government not public Running since December 1995 without a single published effectiveness figure — every rebound claim about it is borrowed from Mexico City.
