Overview
- Provisional Measure 1.343/2026 took effect after publication on March 19, making the CIOT mandatory for every road-freight operation and linking it to the MDF-e for automated, nationwide oversight.
- ANTT must refuse CIOT issuance for contracts priced below the freight floor, preventing those freights from being formalized at the point of contracting.
- The measure sets a R$10,500 fine per unregistered operation, allows RNTRC suspensions and eventual cancellations for repeat underfloor hiring, and authorizes R$1 million–R$10 million fines per irregular operation in reiterated cases.
- Responsibility for issuing the CIOT falls on the contracting party when hiring an autonomous trucker and on the transport company in other cases, with autonomous truckers excluded from suspension and cancellation penalties.
- ANTT has seven days to issue operational rules and will set the start date for mandatory CIOT registration, while the transport minister pledged more frequent freight-table updates and said two portarias next week will detail penalties and CIOT operations.
