Speeding 51 in a 40 @4.47AM
Your road traffic offence question: Could this be contested on tech grounds.?
That would depend on whether or not any technical grounds exist….
In order to see the full evidence in the case you would have to reject the ticket and ask for a court hearing. You would then need to go through the evidence and figure out whether or not there are any failings in the workings of the device or the officer’s statement.
You put yourself at risk of higher fines and court costs if you reject the ticket and take the matter to court without having a good defence. You should only reject the ticket if you don’t believe you were speeding in the first place
