Protests by bus and truck drivers over increasing fuel prices continued throughout Bulgaria on May 30. This was the last day for which the Sofia municipality granted permission to protest on Sofia's ring road, deputy mayor of transport Velizar Stoilov told private broadcaster bTV.

About 180 trucks gathered on Sofia's ring road at 9am to join the protest. Police escorted protesters, while at noon they drove from Kazichene to the Boyana borough. Cars joined the protests, as well as buses. About 150 buses were expected to arrive from Veliko Turnovo, including companies from Strazhitsa, Polski Trumbesh, Gorna Oryahovitsa, Lyaskovets and Svishtov, Focus news agency said.

Intercity bus drivers protested at the Sofia central bus station. Protests at the bus station finished at noon when the police started to redirect buses that attempted to enter the bus station but couldn't as their places were occupied by protesting buses.

The passengers waiting for intercity buses were nervous, but supported the protests. According to them it was better to wait for an hour today than for the bus ticket prices to raise, Focus news agency reported.

In Varna, 15 public transport bus lines and several private bus companies stopped work for about an hour to join the national protests. Regional representative of the National Transport Union, Maxim Petrov, told Focus radio Varna transport companies throughout Bulgaria refused to sell tickets for travel dates after June 6, when the final protest was expected and all bus transport would be stopped.

Transport in the city of Pernik, about 30 km south of Sofia, stopped between noon and 1pm on May 30. Three intercity bus lines from Pernik joined the protest. Teacher trade unions joined the protest, saying that fuel price increases meant price increases for public transport tickets, which would lead to teachers not being able to buy tickets to go to work. Passengers had not been informed of the protests and had to wait for their buses for one hour.

Owners of 64 transport companies from Dupnitsa submitted a request to the town's mayor Atanas Yanev in which they demand a 10 per cent increase in the ticket prices. Contracts between the municipality and the 64 companies stipulate that they have the right to request a ticket price increase in the case when fuel prices increase with 20 per cent or more. If an agreement would be reached, ticket prices in Dupnitsa would increase by 20 stotinki, or 30 per cent, to 0.80 leva, while tickets to the nearest towns and villages would cost one lev.
