I got caught driving without insurance once, points and fine (my mate was pissed and I didn’t want him driving so drove his car). I set up a standing order to pay the fine as I was on a low income at the time.
Somehow this got cancelled and I, stupidly, didn’t realise or do anything about it. I owed about £150..
Long story short, got a letter to go to court. Turned up, explained what had happened..
Got sentenced to 2 weeks prison! Luckily made my one phonecall home and my parents came in and paid the fine off.
2 **** weeks for £150!!
Meanwhile, my ex-brother-in-law, who had abused my sister, smashed her car up, threatened her with a knife was told to try and be a better person and do 50 hours community service..
Good luck with your case.
