Roughly one-third of all cars on Greek roads has not passed a roadworthiness test (KTEO) in the last three years, according to figures made public yesterday by the owners of private KTEO centers. They said that of the 7.5 million vehicles in Greece, 2.7 million have not been brought in for testing, which is costing the state more than 1 billion euros in unpaid fees and penalties, the KTEO owners’ union said. New cars have to undergo a KTEO test three years after registration and then every two years after that. It is estimated that 800,000 to 1 million drivers have failed to bring their cars for testing in each of the last three years. The KTEO owners also highlighted allegations of bribery at state testing centers, claiming that drivers pay between 10 and 300 euros to have their vehicles pass inspection, while truck drivers pay 700 to 1,000 euros in kickbacks.
