In the early morning hours of Saturday, 4 October 2014, Blažič caused a traffic accident while driving under the influence, slamming his Volkswagen Golf into the back of a taxi vehicle while changing lanes at the corner of Nemanjina and Resavska streets in central Belgrade. No injuries were reported as the traffic patrol administered a breathalyzer test on the twenty-four-year-old KK Crvena zvezda basketball player, determining his blood alcohol level was above the 0.5‰ legal limit in Serbia.[13] Several hours earlier, Friday evening 3 October 2014, Blažič had played in KK Crvena zvezda's opening game of the 2014–15 Adriatic League season versus Levski Sofia,[13] an 85-55 blowout win in which he contributed 8 points including a spectacular dunk.[14] [15]
Later in the day, after paying the RSD16,000 (~€135) fine to the misdemeanor judge,[16] Blažič publicly apologized "to the taxi driver whose car I hit, as well as to my club and its fans"[13] while his club Crvena zvezda fined him according to its own disciplinary code of conduct by reportedly docking the amount of two monthly salaries from his pay.[16]
