I have three points on my licence.
I live in Wales and have just got a speeding notice when I was travelling at night in the dark from an event on back roads. I have been caught in a 20 mph area. I probably did not see the 20mph sign in the dark and my sat nav has not always updated from 30mph to 20mph, especially in more remote areas.
Is there any tech to stop me from speeding? Thanks.
