The Competition Board has opened an investigation with the decision of 27.04.2017 on the sevenguardrail producers and their association (TOD). The Board has alleged that these producers restrictedthe competition in the guardrail tenders by determining jointly their bids (price quotations) in thesetenders under TOD. In this article, it was analyzed whether a competition infringement occurred or notby using a wide range of data on guardrail tenders. The results showed that the ratios between pricequotations of producers and the approximate costs announced by the Administration (bid / approximatecost) have increased in 2016 as claimed by the Board. However, this increase did not arise from the factthat TOD members who are parties to the investigation are in a cooperation restricting the competition.Instead, the reason for this increase is that the actual costs incurred by the producers increased whilethe approximate costs announced by the Administration in 2016 fell.
