Chuy is a border town of 11 000 inhabitants between Uruguay and Brazil. Something similar to Valga-Valka between Estonia and Latvia, so that the border between them is a wide two-way street called International Street, or to be more exact, the four-way street - so that one two-way is from Uruguay ś side and the other two-way street is from Brazil `s side.
Since I was not intending to get out of this town to Brazil (after all I had no visa ), then I drove on towards Uruguay. While leaving the town there was a police check post by the road. They examined the Estonian registration plate and car temporary admission papers, and after a brief Spanish-English language conversation I could go on.
