Tráfego vs. tráfico
In Portuguese, the words tráfego and tráfico look and sound very similar, but their meanings are drastically different. A single vowel change distinguishes a neutral term for movement from a serious term for illegal trade. Understanding this difference is crucial for correct communication.
Tráfego
A2The word tráfego refers to the movement or flow of vehicles, people, or data. It is the direct equivalent of the English word traffic in its general, non-criminal sense.

Tráfico
B1The word tráfico refers to illegal trade, commerce, or smuggling. It is used to describe criminal activities like trafficking in drugs, weapons, or people.

Summary
In essence, the difference is one of legality and context. Use tráfego for the legal and general flow of things like cars on a highway, planes in the sky, or visitors to a website. Use tráfico exclusively for illegal trade and criminal activities, such as smuggling drugs, weapons, or people. Confusing the two can lead to a significant and often severe misunderstanding.
