Jurisdiction

State of Tamaulipas · Mexico

Tamaulipas is the state of the international bridges: Nuevo Laredo, Reynosa and Matamoros move a huge share of overland trade with the United States, and Highway 85 towards Monterrey, 101 towards Ciudad Victoria and 180 towards Tampico and the port of Altamira spread that traffic of trailers, buses and maquiladora pickups across the whole state. Urban infractions are issued by the municipal transit offices and state ones by the state police; debts are collected with the state’s annual renewal.

## Context and authorities

As in the rest of the country, traffic fines are administrative sanctions set in UMA by the state regulation, with a discount for timely payment in many entities and surcharges once overdue; pending debts block vehicle procedures. For local procedures and rules, the starting point is the [Tamaulipas Government portal](https://www.tamaulipas.gob.mx/).

Each border city and each municipality in the south has its own transit office and treasury, with their own regulations and discounts; the state police covers the state highways and the National Guard the federal stretches, starting with 85 and 2. The state finance secretariat adds infractions to the vehicle debt and does not release the renewal or the plate cancellation while final infractions are pending.

## What the API returns for this entity

In Tamaulipas 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 Tamaulipas are also checked on the state portal described below.

## How to check a plate in Tamaulipas

To check a plate by hand, the [Tamaulipas Government portal](https://www.tamaulipas.gob.mx/) is the entity’s official channel and the [REPUVE](https://www.gob.mx/sesnsp) confirms the vehicle’s identity before any procedure. With ten units that is enough; with a hundred, the API walks the integrated sources by plate and returns the result split by authority, with the folio and amount each one publishes.

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

Transport fleets crossing the Nuevo Laredo or Reynosa bridges several times a week pile up state infractions on Highway 85 and municipal ones in the border cities, with units rotating between operators; the notice reaches the company’s base in Monterrey or Tampico weeks later. Looking up each plate at month end, with the result stored per authority, lets you assign the infraction to the trip’s operator.

For a company cancelling plates or moving units to another state, a plate lookup before the procedure avoids discovering at the counter that a final debt blocks it.

## How to integrate

A lookup is a POST with the plate and, optionally, the entities 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](https://apinitro.com/en/articles/asynchronous-api-retries-without-duplicate-work/) guide explains how to retry without duplicating work and the [API page](https://apinitro.com/en/apis/traffic-fines-mexico/) details access.

JSONIllustrative example, not a contract.

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

## 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.
