boa iniciativa

Keep it simple, the main reason for the fog hazard is low visibility. In addition to smoke, heavy rains are also reasons for this type of situation, so to solution this issue globally, it is not necessary to create new hazards, but just decide an translation adjustment in the fog hazard

Principalmente em Rodovias isto é fundamental.
Já passei por locais onde a fumaça densa impedia de ver qualquer objeto a 20mts de distância, e os motoristas despreparados ainda ligam farol em luz alta, o que é altamente contraditório, pois deveriam usar os faróis de neblina que praticamente todo veículo sai de fábrica.

Yup! fog and smoke for us drivers its the same thing

Onde moro na região que trafego é comum principalmente no verão os incêndios a beira da pista com muita furmaça as vezes sendo exigido até parar o veiculo por falta de visibilidade, seria muito importante ter esse aviso de fumaça disponivel como alerta no waze.

I'd like to clarify that this suggestion does not fall under crisis scenarios.

Here, we are dealing with roadside fires, which are usually small but can generate smoke that significantly reduces visibility.

Although temporary, the impact on visibility can be just as severe as fog, which already has a dedicated alert.

This may not be common in some countries due to humidity levels or vegetation types, but in Brazil and other tropical regions, it is more frequent.

A possible solution could be to group fog and smoke under a single alert, perhaps labeled "Low Visibility" or simply "Fog/Smoke."

Yes, there is a fog hazard option but no smoke hazard yet smoke can cause worse visibility than fog.
