I have only been driving a year and a half and was caught speeding, doing 50 in a 30 will I get banned
It’s unlikely that you will be banned, but you are in the sentencing bracket that suggests that you will get 6 points or a short ban. If you get 6 points then your licence will be revoked under the new drivers act rules.
I can help you with this matter. We may be able to persuade the court to give you 5 points or a very short ban rather than 6 points which would mean that you have to do a full retest.
