Cultural Tip
In Brazil, many drivers keep a spare tire (pneu sobressalente) and a manual jack in the trunk. If you’re on a highway, it’s common to call a roadside‑assistance service (socorro de estrada) or a tow‑truck (guincho) rather than attempting the change yourself, especially at night or on busy roads. Always turn on the hazard lights (pisca‑alerta) and place a warning triangle (triângulo de segurança) about 30 meters behind the vehicle.
