Quilmes is an industrial and riverside partido in the southern suburbs: the Buenos Aires–La Plata motorway, Calchaquí avenue, 12 de Octubre avenue and Camino General Belgrano connect downtown Quilmes, Bernal, Ezpeleta and San Francisco Solano with the City and with La Plata, with speed and red-light cameras on the main corridors. Municipal fines are issued by the partido; motorway and provincial fines coexist on the same plates.

Context and authority

The framework is the National Traffic Law 24.449, which Buenos Aires adheres to: fixed units, two-year limitation for minor offences and five for serious ones. The municipal misdemeanour court rules on fines issued within the partido; route fines and those of the provincial authority are explained in the Buenos Aires article.

The municipal misdemeanour court rules on fines issued within the partido: speeding and red lights on Calchaquí avenue and the camera avenues of Bernal and Quilmes Oeste, lanes and manoeuvres at the motorway approaches and parking downtown and on the riverside. A defence is filed with the court within the period set by the notice; motorway fines are not municipal.

What the API returns for this jurisdiction

A plate lookup in Quilmes walks the Quilmes municipal misdemeanour court together with the integrated provincial sources of Buenos Aires, and returns each fine with the authority that issued it:

  • Authority and fine number exactly as each court publishes them.
  • Date, location when reported and description of the infraction.
  • Amount, status and payment conditions published by that court.
  • Downloadable payment slip when one exists.
  • Coverage per source and partial-result flag.

How to check a plate in Quilmes

A plate is checked by hand at the Quilmes municipal portal, in the provincial sources explained in the Buenos Aires article and at the ANSV national lookup. The API does the same round at scale and returns each fine with the authority that issued it, so verification becomes part of the process rather than a spreadsheet.

What to watch if you run a fleet in Quilmes

A distribution fleet going down Calchaquí avenue towards Solano and Varela crosses speed and red-light cameras on every trip; the fines reach the owner’s address weeks later. Looking up each plate at month end, with the per-source result stored, assigns each fine to the driver and covers the defence in time.

For a company based in Quilmes with units that also travel through Avellaneda, Lanús and La Plata, the same lookup returns each court’s fines separately; reading it per source avoids closing a month with a court that publishes late.

How to integrate

A lookup is a POST with the plate and, optionally, the jurisdictions to include; the initial response accepts the job and the result arrives by status lookup or webhook, because official sources answer in seconds or minutes. The asynchronous APIs guide explains how to retry without duplicating work and the API page details access.

Limits and considerations

  • Fines on the Buenos Aires–La Plata motorway belong to the concessionaire or the province, not the municipality; the response names the authority of each.
  • Fixed-unit amounts are converted at the value current at the source; the final amount is set by the authority at the time of payment.
  • A source that does not answer is reported as such, never as an absence of infractions.
  • The API neither pays fines nor handles defences; it delivers information to decide.
