Avellaneda is the southern gateway to Buenos Aires City: the Pueyrredón bridge, the Buenos Aires–La Plata motorway, Mitre avenue and the access to the Dock Sud port move petrochemical trucks, buses and private cars across the Riachuelo every day. Municipal fines are issued by the partido on avenues and camera-equipped traffic lights; provincial ones overlap on the same plates.

Context and authority

The partido adheres to the National Traffic Law 24.449 through the provincial law: fines are expressed in fixed units and lapse after two years if minor and five if serious. Municipal fines are ruled on by the partido’s misdemeanour court; those issued by the province follow their own circuit, described in the Buenos Aires article.

The municipal misdemeanour court rules on Avellaneda fines: red lights and right of way at the camera-equipped intersections of Mitre avenue and the bridge approaches, lanes and manoeuvres in Dock Sud and downtown, and speeding on the ring avenues. A defence is filed with the court within the period set by the notice.

What the API returns for this jurisdiction

In Avellaneda the API queries the Avellaneda municipal misdemeanour court and, in the same lookup, the other integrated sources of Buenos Aires; it returns each fine with the authority that issued it:

  • The authority that issued the fine and its number, unnormalised.
  • The date and description of the infraction, with the location if the court reports it.
  • The amount and status current at the source, with the payment conditions it publishes.
  • The link to the payment slip when the authority offers one.
  • Which sources answered and which did not, to tell a complete result from a partial one.

Sample: 1.000–5.000 fine records, 50.000+ lookups · See the data methodology

5% of the plate lookups in the period found at least one Avellaneda fine without a recorded resolution. The dominant category is red lights and right of way, more than half of the fines observed; lanes and manoeuvres and speeding split almost all the rest.

The median amount band is ARS 250,000 – ARS 500,000 and the median age of open fines is 190 days, the lowest among the southern partidos we publish: Avellaneda fines get resolved or paid faster.

42% of the fines offered voluntary payment at lookup time, less than half, so the discount depends on looking up early.

The fleet cohort, 50 accounts with twenty or more plates and 2,040 plates in total, found at least one Avellaneda fine in 6% of its lookups, in line with the general public.

For a truck fleet going in and out of Dock Sud, the red-light camera is the main risk: an amber crossing on Mitre avenue becomes a fine weeks later. Looking up each plate thirty days after each month of operation, with the per-source result stored, lets you assign the fine to the driver and use the discount while it exists.

How to integrate

Each plate is sent in a POST, with the jurisdictions to include if you do not want to query all of them. The response accepts the job and the result is retrieved by status lookup or arrives by webhook once the sources finish answering. The vehicle lookup quality guide explains how to handle partial results and the API page details access.

JSONIllustrative example, not a contract.
{
  "plate": "ABC123",
  "jurisdictions": [
    "AR-B-avellaneda-buenos-aires"
  ]
}

Read the result per source: the municipal court and the provincial source answer separately, and the partial-result flag says whether any failed to answer. The vehicle lookup quality guide explains how to handle that case.

Limits and considerations

  • Fines from the Pueyrredón bridge and the motorway may be provincial or City fines, not municipal ones; 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.
  • Proprietary data comes from user lookups, not from a registry: the share of fines is skewed towards suspect plates.
  • 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.
