My speedo and my Tom Tom don't agree.
Nov 15, 2010
I have a new car and a new TomTom and my car speedometer and TomTom speed vary up to 5 miles an hour. I have assumed my TomTom is the more accruate which is the higher speed and then get a notice of speeding at 36 MPH. Has anyone sucessfully defended a claim based on the variance in speed from car to device? Never had a speeding notice before in 20 years of motoring- may throw TomTom in bin!

You can only defend a speeding matter if you can cast a doubt on the reliability of the police evidence. The court may take into account the reading from your Tom Tom or your speedo - but if they are both less accurate that the police speed detection device - which I anticipate they are- you wont win.
It may amount to a special reasons argument to show that either one of the devices misled you into thinking that you were going slower than you thought - but it would not be a defence. A successful special reasons argument would allow the court to agree not to give you the penalty points.
Come back to me if I can assist further and if you would like to take the matter to court to try and challenge it.
