Free Traffic Legal Advice

I have been sent a NIP of an alleged offence of 59 in a 50mph temporary roadworks with a picture taken by a camera van parked at the side of the road. I don't doubt or dispute that I was travelling at 59mph, but I'd like to see some evidence that the 50mph limit was correctly put in place. Where do I find this information or do I have to challenge the prosecution and put them to strict proof that the 50mph limit was correctly and legally instituted?

Thank you, @FuzzyDuck, for your swift reply. I have all those. If you use their online portal, you are given only the option of accepting guilt online or challenging - by post. I don't want to do either of those just yet; simply confirm it was me. I have waited for the traditional paper S172 form so I'm happy to complete that and agree it was me driving. However, I remember comments made on the original Pepipoo site that it was extremely rare for roadwork speed limits to be set up in compliance with the legislation and, having won a case against a council after proving their road signage was incorrect, I know it can happen. I am quite happy to do some legwork but don't know where to start looking.

Bear in mind ha you must respond o the request for driver's details within the 28 days allowed and you must respond to it even if you establish that the limit was not lawful.

Yes Highways England put the limit in place with support from the police, council and local councillor after the recent fatality there. I think the temporary order may  have been published in the Cornishman newspaper, or whichever one covers that area.

I have been unable to locate the TTRO online, although I have now found that the roadworks are listed as NOMS-406547. Having checked that no previous FOI request has been made for this information, I have therefore today submitted an FOI request to Cornwall Council.

Thank you; that was posted yesterday.

Thanks, 666; the request was couched as a request for supply of the document in the first instance and FoI if it wasn't otherwise available. As the holding reply has come from their FoI department, different from that I sent it to, I surmise that it is going to be handled as an FoI.

I've found this public notice online.
