Free Traffic Legal Advice

You appear to be going faster than the vehicle in the inside lane. So unless they are travelling significantly under the speed limit, that you probably were above it.

What speed is alleged?

81 is the detected speed according to the photo.

Simple name the driver (yourself?) ASAP. You should then get an offer of a fixed penalty of 3 points and £100. Accept that and that will be the end of the matter.

The Band B stuff only applies if the matter goes to court, this shouldn't happen. Fixed penalties are offer up to 25 MPH above the limit (exception is a 30 limit where it s up to 20 MPH above). So in a 50 limit any speed below 75 should see a fixed penalty offer.

And there you have the answer (eventually). So forget any late NIP defence and get her to get on and admit being the (assuming she was).

what makes you think I get arrested? would they do that for dangerous driving? what beneift would it give them?

It's just about a given you will be arrested, so they can caution you and use what you say as evidence. This isn't going to be some cosy fireside chat.

Be aware if you are arrested, they will ask you if you want legal representation (i.e. a duty solicitor). If you say yes and there is a delay getting hold of one, you could find yourself put in a cell for the duration (been there, got the t-shirt).

The requirement to send in the physical driving licence ceased years ago, nowadays just the details contained on it are required. During the whole process you have to supply the drivers number twice:

 1) When naming the driver

 2) When accepting the fixed penalty

Is it possible you did it the first time but not the second? This seems to be quite a common mistake.

Sounds like a council matter not criminal.

I'll alert a mod and get them to move it.

I have a clean record and I'm a civil servant would this help my case at all?

Nope, once found guilty of the S172 offence, sentencing will follow the guidelines. Why would being a civil servant get you any leeway?
