Abramet study reveals driver's license restrictions in Brazil

A study by the Brazilian Association of Traffic Medicine (Abramet) reveals that between 2015 and 2024, 289,503 driver's licenses (CNH) in Brazil were issued with specific annotations or restrictions. Because a single license can contain multiple requirements, the study identified a total of 861,504 annotations, averaging three per license.

Vehicle adaptations account for 68.1% of all annotations. The most frequent requirement is the use of automatic transmission, representing 15.3% of cases (131,674 records), followed by the mandatory use of corrective lenses (14.5%) and power steering (11.8%). Other notable restrictions include monocular vision, left-side accelerators, and the use of hearing aids.

Regionally, the state of Acre recorded one of the highest proportions of annotated licenses, with 469 per 100,000 inhabitants, ranking fourth nationally. Rondônia, Tocantins, and Mato Grosso do Sul reported higher proportions. The data was extracted from the National Registry of Habilitated Drivers (Renach), managed by Senatran.
