50mph in a 40mph incoming to Camera, Vehicle exiting and no secondary lines on my carriagway

Hi,

I am new here so please shoot me down if I have got this wrong I am happy to learn.

I have got a ticket from a camera in Somerset on the A38 the NIP say 50mph in a 40mph, this is not a new speed camera and I frequently drive past it so either a momentary lapse or a fault on the camera, Other people locally on facebook are reporting similar issues and wondered there genuinely could be an issue. Teh calibration certificate for the camera shows a difference in secondary Check Distance Specified 10.2m Distance Measured 9.83m. The Camera is a Sentio Shield, which I understand does not require lines on the road however Avon and Somerset guidelines seem to state they rely on sensors or road markings for secondary checks, so wondering if this calibration difference could be significant.
Also in the image form the VIP My car approaching the camera is almost side by side to a vehicle driving away from the camera, there are road markings on the side driving away but not on the approaching side.
Just wondering id two vehicles side by side, lack of markings or calibration differences in anyway amount to a defence?

Thanks in Advance

Probably not.

But the bottom line is that the device is assumed to be reliable and accurate unless the contrary can be proved. The burden to provide that proof rests with you.

It is unlikely that you will be able to present an argument which has a chance of success without expert help. You will have to pay for that and if you are unsuccessful, you will have to pay for the prosecution’s expert, who they will almost certainly hire to counter yours.

Depends if you want to risk a bill of a least £1,000 (and possibly much more, plus your own costs) against a certain £100 for a course or fixed penalty.
