So about 2 months ago I was stopped by police for driving with no insurance. Then stupidly I done the same thing again the other night and was caught driving with no insurance and under the influence of marijuana. It's my first ever criminal or driving offence of any kind and I didn't cause any damage or drive dangerously either time, however I've only had my licence about a year and a half(UK) and as both offences are so close together I am worried as to what my punishment will be. I haven't been summoned for either offence as of yet. I understand I'm getting a ban and a big fine, but is there a chance I could go to prison too?
