Heavy Haul Permit Guide
in Brazil 🇧🇷

Obtaining the correct aet - autorização especial de trânsito is a critical step for any transporte pesado or carga indivisível movement in Brazil. This guide covers the permit types, application process, timelines, and common pitfalls to help you navigate the regulatory landscape efficiently.

Brazil typically offers several categories of transport permits: single-trip permits (for one specific movement), annual/blanket permits (for frequent shippers moving similar loads), carga superdimensionada permits (for exceptionally large or heavy loads requiring special engineering review), and multi-jurisdiction permits (when your route crosses regional boundaries within Brazil). Each type has different requirements, processing times, and costs.

A standard aet - autorização especial de trânsito application in Brazil requires: complete vehicle specifications (tractor, trailer, load), exact dimensions (width, height, length, overhang), gross and axle weights, proposed route with start and end points, preferred travel dates and times, proof of insurance, and operator certification details. For carga superdimensionada applications, you may also need engineering analyses for bridges and road structures along the route.

Standard aet - autorização especial de trânsito applications in Brazil are typically processed within 1–5 business days. carga superdimensionada permits may take 2–8 weeks due to engineering reviews. Tips for faster processing: submit complete and accurate applications, apply during non-peak periods, maintain good standing with permitting authorities, and consider using permit services available through Haul Command operators in São Paulo, Rio de Janeiro, Belo Horizonte and across Brazil.
