Stalemate in cargo transportation in Teresina exposed difficulties in the implementation of the new CIOT, affected drivers stranded for weeks, and led companies to redo fiscal documents to unlock operations amid adaptation to the new ANTT rules.
Truck drivers who had been waiting for more than 20 days at the South Business Hub in Teresina began to be gradually released after a stalemate related to the issuance of the Transport Operation Identifier Code (CIOT), a document required in paid road freight transport operations covered by the new rules of the National Land Transport Agency.
The retention of cargo led companies in the sector to cancel more than 300 already issued invoices and redo the documentation through another platform, according to representatives of the transport companies.
The release of vehicles began to occur gradually, while teams tried to regularize the necessary records to allow the continuation of trips.

The problem mainly affected truck drivers who were already loaded and depended on fiscal and operational documentation to continue their journey.
In the case recorded in Teresina, drivers remained stopped near an iron industry in the Industrial District, waiting for the release of the cargo.
The requirement to generate the CIOT for operations covered by the new rules came into effect on May 24, 2026, at 6:00 PM, as informed by ANTT.
The agency states that the code is now required to identify and monitor paid road freight transport operations, within the model provided by federal regulation.
Cargo began to be released in Teresina
Sector representatives stated that teams worked overnight to cancel fiscal documents that had already been generated and issue new invoices through another system.
The measure was adopted to unlock operations that were stopped and allow truck drivers to gradually leave the location.
The expectation informed by business entities is that normalization will occur in a staggered manner, with the completion of releases over three to four days.
The deadline, however, depends on the documentation regularization of each operation and the capacity to reissue the required records.
The president of the Union of Cargo Transport and Logistics Companies of the State of Piauí (Sindicapi), Humberto Lopes, stated that the impasse was not restricted to Piauí.
According to him, the system implementation occurred without a period considered sufficient for companies to adapt, which would have caused impacts in different states.
Lopes also said that entities linked to cargo transport took legal action and requested a 60-day period from ANTT for adaptation.
The claim, according to the sector representative, seeks to reduce losses accumulated by companies and drivers during the implementation phase of the new requirements.
ANTT speaks of occasional instabilities in CIOT
ANTT reported that occasional instabilities were recorded in the first days of implementation, but stated that these problems have already been overcome.
The agency also declared that most operations did not need to resort to the contingency mode provided in the regulation.
According to the agency, approximately 1 million CIOTs had already been generated since the start of the new model’s operation.
Of this total, more than 80% were registered without the need for contingency use, a mechanism created for exceptional situations of unavailability or operational difficulty.
ANTT maintains that the contingency was precisely planned to avoid disruptions in cargo transport.
In this model, the transporter can register the operation locally and start the journey, provided that the information is subsequently transmitted to the agency within the regulatory deadline.
The maximum deadline for regularization is 168 hours, equivalent to seven days.
Even in these cases, other legal and regulatory obligations remain valid, such as the registration regularity of those involved, correct declaration of operation information, and compliance with the Minimum Freight Rate when applicable.
New CIOT expanded controls over freight
The CIOT is used to identify the transport operation and monitor data related to the freight contract.
With the new rules, the system has taken on a broader role in electronic monitoring, including the verification of declared information and integration with obligations related to freight transport.
The regulation that expanded the requirement was published in 2026 and was based on changes promoted by ANTT Resolution No. 6,078, of March 24, 2026.
The rule altered previous rules on the registration of the transport operation necessary for the generation of the code.
In practice, companies and carriers began to deal with a more stringent validation process before the start of the trip.
This new format increased the reliance on integrated systems and enabled platforms, which helps explain the operational impacts reported during the first days of enforcement.
ANTT states that the requirement began only on May 24, 2026.
Therefore, the agency says there is no direct relationship between the new requirement and reports of stoppages that would have occurred before this date, although companies report adaptation difficulties during the transition period.
Companies report losses during adaptation
For the freight transport sector, the main criticism is the preparation time to comply with the new rule.
Carriers state that the change required adjustments in systems, reorganization of internal routines, and revision of fiscal procedures in a period considered short by business entities.
In addition to the wait for truck drivers, companies reported costs with documentary rework, cargo reorganization, and delays in merchandise delivery.
The cancellation of more than 300 invoices in Teresina became the main local example of the operational impact caused by the impasse.
Drivers were also affected by the delay, as staying for several days in loading areas can generate extra expenses for food, lodging, vehicle maintenance, and loss of new trips.
Sector representatives state that these losses will still be calculated by the companies involved.
Although ANTT highlights the use of contingency as an alternative to avoid blockages, carriers state that the practical application of the procedure raised doubts at the beginning of implementation.
The agency, in turn, provided guidelines and frequently asked questions about the CIOT to guide companies, drivers, and other users.
Release of cargoes should progress gradually
The departure of truck drivers from the South Business Hub began to depend on the completion of the stages of document reissuance and operation validation.
As part of the loads were already linked to canceled tax documents, regularization needed to occur before the resumption of travel.
The sector expects the release to be completed progressively, without a new widespread blockade of operations.
Even so, business entities advocate for an additional adaptation period, arguing that companies need more time to adjust systems and train teams.
ANTT maintains the understanding that the regulation already provides sufficient mechanisms to ensure the continuity of transport, even in cases of instability.
The agency also reinforces that the contingency mode does not eliminate the obligations provided for in the regulation, it only allows the continuation of the trip in exceptional situations.
With the gradual release in Teresina, the impasse enters a phase of operational normalization, but leaves open the discussion about the effects of the implementation of the new CIOT in road freight transport.
For companies and truck drivers, the central point remains the balance between inspection, technological adaptation, and logistical continuity.
