22 November 1985,
In Euskal Herria Euskaraz blocked the Zarautz toll. A motorhome was formed asking for the toll of the motorway in Euskera, and since the A8 motorway did not offer it, one at a time complained in the claims book, causing great bottlenecks. Once the complaint was filed, they let everyone go unpaid. A while later, they began issuing in Basque the toll bill.
