Gardai arrested 16 motorists in the same town over the May bank holiday weekend.
The drivers were arrested for a number of offences in Killarney, Co Kerry.
Four people were nabbed on suspicion of drink or drug driving, while 12 were arrested for dangerous driving as they attended the Rally of the Lakes event.

The 12th person was charged to appear before the courts later this month.
