I've received a speeding fine for doing 37mph in what the police are stating is a 30mph road. I was using my sat nav at the time and it clearly stated that it is a 40mph road. Also, when I entered the town on the same road, there are two large 40mph signs. The section of the road I have been accused of speeding on has also had a junction which has a 30mph sign as you enter it, why would that be there if the road is also 30mph?
Do I have a good enough case to appeal? I was ‘caught’ by a police traffic van parked in a lay-by.
