matkustettaessa

Matkustettaessa is a Finnish adverbial participle form derived from the verb matkustaa (to travel). It expresses time or circumstance and roughly corresponds to the English phrase when travelling or while travelling. The form is non-finite and is used to introduce a subordinate clause that states what holds under the given travel-related condition. Matkustettaessa is most common in formal, instructional, or normative texts, such as travel advisories, safety instructions, and official guidelines.

In use, matkustettaessa introduces clauses that describe actions or requirements that apply during travel. For example: Matkustettaessa ulkomaille on muistettava passin voimassaoloaika. This translates to “When travelling abroad, one must remember the validity of the passport.” The construction helps present general rules or recommendations concisely without specifying the subject.
