On April 30, 2014, Janoušek was handed a 3-year prison sentence for a hit-and-run accident that took place in Prague in March 2012. It is claimed that he had been driving drunk when he collided with another car. He ran over the 51-year-old woman driver causing grievous bodily harm when she attempted to stop him from leaving the scene. Janoušek faced ten years in prison. Both the prosecution and Janoušek appealed the verdict. The court eventually decided to increase Janoušek's prison sentence to 4.5 years and raised the term of his driving ban from 5 years to 7, stating that the injury sustained by the other driver was not the result of an accident but of a deliberate criminal act on the part of Janoušek. On November 18, 2014, Janoušek began serving his sentence in the Brno city jail. Both the prosecution and Janoušek appealed to the Supreme Court of the Czech Republic but the verdict was upheld on July 28, 2015.
