The number of drivers prosecuted for motoring offences by magistrates grew by 8% last year, figures have shown.
Almost 54,500 cases were dealt with in 2014, up from about 50,500 in 2013, according to Welsh government numbers.
However, the latest annual figures of fixed penalty notices issued in Wales - 77,000 - dropped by 17%.
The annual report showed men accounted for 68% of the motorists involved in court proceedings in 2014, about the same as 2013.
There were 5,800 positive breath tests across Wales in 2013, a 26.5% drop on the 7,900 recorded the year before, despite there being only 7.5% fewer overall tests.
Last month, figures showed a steep fall in the number of motorists caught using their phone while behind the wheel.
