No, driving with interior lights on in Brazil is not explicitly prohibited nationwide, but municipal and state traffic codes often restrict their use to prevent distraction. The Código de Trânsito Brasileiro (CTB) lacks a specific article, shifting enforcement to local authorities like Detran-SP or Detran-RJ, which may penalize visibility impairments under Article 252 (distraction-related infractions). Recent 2026 compliance drafts by Contran suggest stricter uniformity, but no final ruling exists.
Key Regulations for Driving With Interior Lights On in Brazil
- Local Traffic Codes: Municipalities like São Paulo (via Código de Obras e Posturas) or Rio de Janeiro may classify illuminated interiors as “distracting elements,” triggering fines under Art. 252 of the CTB.
- Visibility Standards: State regulations (e.g., Detran-RS) require interior lights to be dimmed or off if they impair the driver’s view of road signs or other vehicles, aligning with Resolução 960/2022 (traffic safety norms).
- Emergency Exceptions: Interior lights may remain on during medical emergencies, but documentation (e.g., Boletim de Ocorrência) may be required to contest penalties under Art. 165-A (abuse of emergency privileges).
Enforcement varies by jurisdiction, with urban centers (e.g., Brasília, Curitiba) prioritizing stricter interpretations. Drivers should consult local Detran guidelines or municipal ordinances to avoid fines, as federal law remains silent on the matter.
