Two frightening chain accidents occurred on Tuesday 10 November in Bulgaria, on the Trakia highway, one of the country’s main arteries. Cars and trucks collided in conditions of extremely reduced visibility due to thick fog. Some vehicles overturned, others were completely crushed on impact. The governor of the Yambol region, Georgi Chalakov, communicated the number of victims, quoted by the Bulgarian news agency Bta. The accidents occurred near the Zimnitsa interchange, in the south-east of the country, involving both lanes of the motorway. Rescuers had to remove some sections of the protective barriers to reach the people trapped in the vehicles.
