Jurisdiction

State of Michoacán · Mexico

Michoacán links the capital, Morelia, with the port of Lázaro Cárdenas by the Siglo XXI motorway, and with Guadalajara and the Bajío by Highways 15 and 43; in between, Uruapan and the avocado region move thousands of refrigerated trucks towards the northern border. Urban infractions are issued by the municipal transit offices of Morelia, Uruapan and Zamora, and those on state roads by the state police; debts are collected with the state’s annual renewal.

## Context and authorities

The framework is the entity’s traffic regulation and, on federal roads, the federal regulation: fines are expressed as multiples of the Unidad de Medida y Actualización (UMA) and collected as tax credits, with late surcharges. Many vehicle procedures, such as emissions verification or plate renewal, require having no pending infractions. Institutional information is on the [Michoacán Government portal](https://michoacan.gob.mx/).

The state police and the state transit authority issue infractions on state highways and regulate freight transport; the municipalities have their own transit office and treasury, with their own regulations. The state finance and administration secretariat adds vehicle debts to the renewal and to plate procedures, and on the Siglo XXI motorway and federal Highway 15 infractions belong to the National Guard.

## What the API returns for this entity

In Michoacán a plate is sent to the [Mexico fines API](https://apinitro.com/en/apis/traffic-fines-mexico/), which walks its integrated sources and returns each infraction with the authority that recorded it:

-   Authority and infraction folio exactly as the source publishes them.
-   Date, location when reported and reason for the sanction.
-   Amount, status and current discounts published by that authority.
-   Payment line or reference when the source offers one.
-   Coverage per source and partial-result flag.

The response splits the result by source and the partial-result flag shows whether any failed to answer; vehicle debts in Michoacán are also checked on the state portal described below.

## How to check a plate in Michoacán

A plate is checked by hand at the [Michoacán Government portal](https://michoacan.gob.mx/) and, for the vehicle’s identity, at the [REPUVE](https://www.gob.mx/sesnsp). The API does the same round at scale and returns each infraction with the authority that recorded it, so verification becomes part of the fleet process rather than a spreadsheet.

## What to watch if you run a fleet in Michoacán

A refrigerated transport fleet leaving Uruapan for the north crosses Michoacán, Jalisco and several more states on every trip, and the infractions from each reach the company’s base through different channels; looking up each plate at month end, with the result stored per authority, lets you assign each infraction to the operator while the trip log exists.

For a container company at the port of Lázaro Cárdenas, the plate lookup before renewing the registration of the tractor units prevents a forgotten debt from leaving units idle at customs.

## How to integrate

Each plate is sent in a POST, with the entities 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](https://apinitro.com/en/articles/vehicle-data-quality/) guide explains how to handle partial results and the [API page](https://apinitro.com/en/apis/traffic-fines-mexico/) details access.

JSONIllustrative example, not a contract.

```json
{
  "plate": "ABC123A",
  "jurisdictions": [
    "MX-MIC"
  ]
}
```

## Limits and considerations

-   Infractions on federal highways are issued by the National Guard and paid separately from state debts.
-   UMA amounts are updated every year; 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 clarifications; it delivers information to decide.
