A deadly chain-reaction crash on Poland’s S12 near Janówek has left one person dead and six others injured, and police have arrested the truck driver suspected of causing it. The incident happened on Friday before 6pm in the Janówek area, between the Świdnik and Piaski Zachód exits, where the road was narrowed due to repairs. According to police, a 52-year-old Ukrainian truck driver drove into vehicles ahead of him that were slowing down before the bottleneck. The impact triggered what officers described as a “domino effect,” leading to further collisions. The first vehicle hit was a Volkswagen Polo. Its driver, a woman, died at the scene. A second car, a Peugeot carrying a six-person family, was also involved, with three adults and three children taken to hospital for checks. Police said the Peugeot then struck another truck, which collided with a further truck. In total, six vehicles were involved, four trucks and two passenger cars. Two of the trucks were Polish Army vehicles. The 52-year-old driver suspected of the crash was detained and taken into custody. Police said he was sober at the time. After the accident, the S12 route towards Zamość and Chełm was completely blocked and an official detour was set up at the Świdnik junction.
