Questions & Answers about Na autocesti vozač mora ostati u svojoj traci.
Because na autocesti means on the highway / motorway in the sense of location.
In Croatian, na can take different cases:
- locative for being somewhere
- accusative for motion toward somewhere
So:
- na autocesti = on the highway (already there)
- na autocestu = onto the highway (movement onto it)
In this sentence, the driver is already on the highway, so Croatian uses the locative: autocesti.
It is locative singular.
The dictionary form is autocesta (motorway / highway), and after na to show location, it changes to the locative form:
- autocesta → autocesti
So:
- na autocesti = on the highway
