A Kerry test centre has the highest pass rate for HGV driving tests in the country.
According to a new report released by the Road Safety Authority, Tralee test centre has a 91% pass rate for drivers of heavy goods vehicles.
Meanwhile, Killarney and Tralee test centres have similar pass rates for regular car driving tests with 52.7% and 52.8% respectively.
Almost two-thirds of drivers failed their test at Charlestown in north Dublin while 80.5% of drivers in Birr, County Offaly were successful.
Transport commentator Conor Faughnan says the disparity in pass rates has been a big issue for years, and one which isn't being addressed.
