37 in a 30? Hah! - join the club.
I recently challenged my "37 in a 30" NIP in Magistrates' Court, and I won the case. The reason I won it was because the police and local council did not know the law as well as they thought they did. I had been charged under the wrong section of the 1984 RTRA, and was able to prove to the prosecution that the section of the act which had been used in the summons could not lawfully be used in cases involving roads which DO NOT have a system of street lighting.
I have a few questions, the answers to which could affect the outcome of your case if you were to challenge it in court.
- You've said the road was not residential. Does the road have street lighting with the lamps at intervals not exceeding 200yds (England and Wales) or 185 metres (Scotland)?
- Does the road have speed limit signs with repeaters?
- Was this road "always" a 30 area, or has it recently been changed to 30 from 40 or another higher limit?
As far as I can tell, the prosecution process relies heavily on intimidation. You get your NIP/photos and a letter from the police with the word POLICE in big bold letters along the top alongside the name of the force. You then get given the option to roll over, pay a £60 fine and accept 3 penalty points. Most drivers are so traumatised by the NIP and letter that they choose the "fast-track" option of paying up and avoiding court. The whole deal is redolent of the "nice guy, nasty guy" method of police interrogation used by some forces around the world.
Don't be intimidated. The court option is nowhere near as cruel as many people believe. I was very well treated and have no complaints at all. Mind you, I dressed smartly in a suit and silver silk tie - it might have been different if I'd shown up in a pair of jeans and an Iron Maiden T-shirt.
Answer the questions I have asked above, and then we can take it further. In my case, the road did indeed have

signs, and my original case was to show that because of being a rural road, the signs had become obscured by foliage. But then when the summons was brought, I was charged under S81(1) of RTRA(1984), which makes it an offence to exceed 30 on a "restricted road". My defence was a test case that I found in a press release on ABD:
http://www.abd.org.uk/pr/385.htm The allegation that I had "exceeded 30 on a restricted road" was false - not because I did not exceed 30, but because I
wasn't on a restricted road.
