The transport ministry's own standing page for the measure, the correct primary citation for the calendar and the exemption rules. Direct fetch returned HTTP 503 twice from this desk on 2026-07-26; every fact it would carry is instead sourced to the environment ministry and BioBioChile entries below, which agree on dates, comunas, hours and digit tables.

Fetched. Dates the GEC period 1 May to 31 August; states the permanent restriction falls on sello verde vehicles registered 2011 and earlier and motorcycles 2010 and earlier across the Provincia de Santiago, San Bernardo and Puente Alto, with non-seal vehicles banned from the Americo Vespucio ring; gives the weekly digit cycle from 4 May and the 07:30-21:00 window; and states that when Alerta, Preemergencia or Emergencia is decreed further digits are added to the ban. Also the source for the Seremi de Transportes handling exemption authorisations.

Fetched. Names the two instruments behind the episode declaration: the Sistema de Vigilancia de Calidad del Aire operated by the environment ministry, and the Sistema de Pronostico, with MP10 forecasting administered by the Direccion Meteorologica de Chile and MP2.5 by the MMA. The page does not publish the numeric declaration thresholds, so no threshold value is quoted in this entry. The linked Plan Operacional GEC 2026 PDF was retrieved but did not yield legible verbatim text to this desk.

Abstract fetched verbatim and the sole source of every figure in the impact field: 'these temporary bans reduce car trips by 6-9% during peak hours, and by 7-8% during off-peak hours. This is consistent with air pollution reductions during peak hours, and with increases in the use of Santiago's mass-transit systems during hours the systems run with excess capacity.' Also the independent confirmation of the trigger layer, since the identification strategy is 'a fuzzy regression discontinuity design that uses the thresholds in the air quality index used to announce these warnings as instruments for their announcement.'

Abstract fetched. Dates the vintage-specific design to Santiago's 1992 programme and calls it the earliest to use vintage-specific restrictions, which is the basis for this entry's yearStart. Argues that uniform restrictions encourage drivers to buy additional, more-polluting vehicles, while vintage-specific ones can 'yield important welfare gains by moving the fleet composition toward cleaner cars' and should work through which car is driven rather than how much it is driven. Cited for design and dating; it is a modelling paper and carries no measured air-quality result here.

Listed because it is the standard evaluation of Santiago's episode restrictions against measured concentrations from the monitoring network. Fetch returned HTTP 403 from this desk on 2026-07-26 and the abstract could not be read in full, so no figure from it is used anywhere in this entry.

Fetched. Confirms the automated enforcement law is not yet in force, that the transport minister expects it during 2026, and that the four infraction types it will automate include restriccion vehicular alongside red lights, speeding and bus-only lanes. This is the source for the entry declining to claim any camera enforcement today, against several Chilean commercial blogs that assert a 400-point plate-reading network is already issuing restriccion tickets.

Known limits of this passport
- Publisher names and source languages have not yet been classified; domains are recorded without guessing.
- Existing source notes are descriptive locators, not page- or paragraph-exact citations.
- A missing archive, publication date or content hash is shown as null rather than inferred.
- The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
