Aguascalientes is a small state with a single metropolitan area and an automotive industry that grew around federal highway 45: the ring road, Aguascalientes avenue and the southern industrial parks move supplier fleets, staff transport and deliveries within a few kilometres. State and municipal road police share traffic, and plate renewal requires having no debts.

Context and authorities

Infractions are sanctioned under the state traffic regulation, with amounts set in Unidades de Medida y Actualización (UMA) and updated every year; unpaid ones accumulate as vehicle debts and block procedures such as plate renewal, change of ownership or verification. The Aguascalientes State Government portal publishes official information.

The state’s Secretaría de Seguridad Pública, with its road police, issues infractions on the ring road and on state highways, and the municipality of Aguascalientes issues its own on its streets; the Secretaría de Finanzas collects vehicle debts together with plate renewal. Clarifications are filed with the authority that recorded the infraction, within the period set by the notice.

What the API returns for this entity

In Aguascalientes the API queries Aguascalientes’ state plate lookup for infractions and returns each infraction with the authority that recorded it:

  • The authority that recorded the infraction and its folio, unnormalised.
  • The date and reason, with the location if the source reports it.
  • The amount and status current at the source, with the discounts it publishes.
  • The payment reference when the authority offers one.
  • Which sources answered and which did not, to tell a complete result from a partial one.

How to check a plate in Aguascalientes

To check a plate by hand, the Aguascalientes State Government portal is the entity’s official channel and the REPUVE 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 Aguascalientes

An automotive supplier’s fleet going from the industrial park to the assembly plant along the ring road crosses state and municipal checks several times a day; looking up each plate at month end, with the per-source result stored, assigns each infraction to the driver and avoids discovering them at plate renewal.

For a staff transport company with units registered in the state, pending debts block the renewal of the whole fleet in the same month; a plate lookup before the renewal period avoids rejections and uses the early-payment discounts.

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 guide explains how to handle partial results and the API page details access.

Limits and considerations

  • Infractions on federal highways belong to the federal authority, not the state or municipal ones; the response names the authority of each.
  • 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.
