Clare motorists are more likely to see their cars fail the NCT than the national average.
Almost 55% of cars who took their tests at the Ennis Test Centre in 2010 were given the thumbs down by inspectors, compared with the national average of just over 48%.
Only five test centres nationwide failed a higher proportion of vehicles.
In all last year, over 21,300 vehicles were tested in Clare’s Coutny Town, while just over 9,700 of these passed first time.
