Ao ver um pano branco, reduza a velocidade, aumente a distância e observe se há pessoas, fumaça, danos ou risco de nova colisão.

O gesto é um aviso informal, não tem valor oficial no Brasil e pode ter significados diferentes conforme o costume de cada região.

Vale lembrar que o pisca-alerta indica que o veículo está imobilizado ou enfrenta uma emergência, enquanto o triângulo alerta quem vem pela estrada.

A Resolução Contran nº 36/1998 exige o triângulo a pelo menos 30 metros da traseira, perpendicular ao eixo da via e bem visível.

Em curvas, subidas, neblina ou trechos escuros, o triângulo deve ficar mais distante para ser percebido antes do carro parado.
