I'm out of luck・・・

I went to school by bike today.
There was a halt sign on my way to school but I didn't see it, so I was caught by police・・・・・(ﾟ∀ﾟ；；)
I didn't notice that they called after me at first because I couldn't see the sign, however, the fault is mine.
I must pay a penalty of 5000yen by next friday.
Idecided that I will be a safety driver・・・!!!!!!!
Be safety・・・！
