Brazil proposes regulation for courtesy lights between drivers

A new bill, Projeto de Lei 2729/26, is currently under review by the Brazilian Chamber of Deputies. Authored by Deputy Amom Mandel (Republicanos-AM), the proposal seeks to amend the Brazilian Traffic Code (Law 9.503/97) to regulate the use of courtesy lights among drivers.

The legislation aims to authorize the brief use of auxiliary lighting for purposes of gratitude, preventive communication, or general courtesy on public roads. The project emphasizes that these signals are intended to be educational and must not grant the driver any right of way or priority.

To ensure road safety, the bill includes strict restrictions: the use of these lights must be temporary and non-ostensive to avoid distracting or blinding other motorists, pedestrians, or cyclists. Furthermore, the lights cannot replace mandatory signaling systems, and their colors, patterns, or frequencies must not mimic those reserved for official, emergency, or security vehicles. Technical specifications, including intensity and installation requirements, will be regulated by the National Traffic Council (Contran).
