Is that road accident is criminal offence?

[imk1]

I am going to apply for citizenship. Can you please help me about the question 3.13.

3.13 Have you ever been charged in any country with a criminal offence for which you have not yet been tried in court?

I have been in road accident in 2014. Police was arrived on the location and took my and other drivers statements.
Later I received a Police letter saying that they asked the other driver to go for driving improvement course or face prosecution.
At last Police case was closed. No further investigation are required.

- Do I need to tick yes or No in question 3.13?
- Do I need to disclose the road accident information in the application form?

you have not been asked to face prosecution! you don't have any thing to declare
