There are more than a million cars in Attica that have not passed the KTEO roadworthiness test and an increasing number of drivers are failing to turn up for their appointments at test centers, it was revealed yesterday. Owners of a private KTEO center in Athens presented these figures in a letter to the Transport Ministry in which they complained that the lax standards at state-run test centers had resulted in the majority of drivers not bothering to get their vehicles tested for roadworthiness. In 2006, 45 percent of drivers did not turn up for their tests. In 2007, this rose to 55 percent and last year it reached 65 percent. The owners of the private centers claimed that their state-run counterparts do not carry out proper checks and do not keep adequate statistics. KTEO inspections are carried out four years after a car is first registered and then annually after that. The Transport Ministry said earlier this month that it was in the process of setting up Greece’s first roadworthiness tests for the country’s 700,000 motorcycles and scooters.
