The vehicle change before MICIVI’s DGTT is the procedure that lets an authorized transport company substitute a unit in its fleet without having to start the entire authorization process again. It applies to cargo, intercity passenger, school, tourist and taxi transport.

Quick summary: In-person procedure at DGTT. The company keeps its main authorization; only the physical unit linked to the service is changed. Mandatory technical inspection of the new vehicle, DGTT fee, fiscal stamps and a new operation card (15-30 business days).

What is this procedure?

It is the modification of the list of units linked to a transport company’s authorization. It is used when:

  • The company renews its fleet and replaces an old vehicle with a new one.
  • A unit suffers total loss, theft or destruction and must be replaced.
  • The vehicle is sold out of the service and replaced by another.
  • A unit is reassigned from another DGTT authorization within the same company.

The main service authorization (route, category, holder) does not change — only the linked vehicle does.

Requirements

DGTT may request additional requirements per category. This is the general base:

  • Written request addressed to the General Director of Transport, stating the reason for the change.
  • MICIVI form with company data, outgoing unit and incoming unit.
  • DPI of the holder (individual) or patent + DPI of the legal representative (entity).
  • Current resolution of the main service authorization.
  • Vehicle registration card of the new vehicle (in the holder’s name or under leasing/rental contract).
  • Current operation card of the outgoing vehicle (for cancellation).
  • Physical and technical inspection certificate of the new vehicle, issued by DGTT.
  • Current insurance certificate of the new vehicle.
  • Current SAT tax solvency.
  • Payment receipts for fiscal stamps and DGTT fee.
  • Decommission or destination certificate of the outgoing vehicle (sale invoice, accident report, SAT removal).

If the new unit has different plates from the outgoing vehicle, new operation cards are issued. Internal fleet numbering changes in the DGTT registry.

Steps

1. Gather the documentation

Verify the new unit complies with the authorized category (cargo, intercity, school, taxi). Compile the registration card, insurance, invoice and technical certificate of the new unit.

2. Schedule the physical inspection

DGTT inspects the new unit (mechanical condition, cargo or passenger capacity, exterior identification, safety equipment). If it does not comply, fix it before submission.

3. Submit the file at DGTT

Hand in the request, form, DPI or patent, current resolution, registration and operation cards, inspection certificate, insurance and SAT solvency. DGTT calculates the fee and issues the payment order.

4. Pay the fee and stamps

Pay the administrative fee and buy the fiscal stamps. Keep the receipts.

5. Resolution and new operation card

DGTT issues the vehicle change resolution, cancels the operation card of the outgoing vehicle and delivers the new operation card that must be carried in the new vehicle.

6. Update SAT and plates if applicable

If the outgoing unit is sold, complete the SAT vehicle title transfer. If the outgoing unit is permanently decommissioned, process the SAT vehicle removal.
