Cultural Tip
In Brazil and Portugal, safety checks are taken seriously, especially in transportation and industrial settings. Using the informal imperative ‘verifica’ signals familiarity, but in a professional environment you might prefer the more formal ‘verifique’. Also, many Brazilian drivers habitually check the car’s sensors (fuel, oil, tire pressure) before a trip, so the phrase feels very natural in everyday conversation.
