I was convicted of traffic offence in the UK in 2007 when I was a student there (Indian national). It was driving without full license and insurance. The punishment was some fine and 6 points on the learner's license. I left the UK in 2010 and have been living in India since.
I want to apply for an Ireland tourist visa and there is question "Do you have any criminal conviction in any country" but there are no other details like whether "criminal" includes traffic convictions too and whether we have to declare spent convictions.
