Hi,

If a copper is on the side of the motorway pointing a handheld gun and there is another in the car, are they going to be noting down number plates?

Also does the 10%+2mph rule still apply?

Cheers.

I believe they must stop you at the time of the incident. Yes as a rule 10% +2 to allow for speedo inaccuracy.

10%+2 is an ACPO guideline, not a rule. You can be done for 1 mph over the limit, although highly unlikely.

They can note your number and send you an NIP.

Believe that all you want, it doesn't make it so.

Photographic evidence or stopping you at the scene and tricking a confession out of you certainly makes prosecution a lot easier, but it's not required in order to send out a slew of NIPs and section 172s.

It could be that some forces have decided to just note down reg numbers and speeds and then see how many folk roll over and accept FPNs - or better yet, pay up for "Speed Awareness" courses run by the Chief Cuntstable's brother-in-law. They may get more absolute numbers that way than stopping at the scene.

Heck, they could probably just note down every reg number on most honeypot roads: how many people actually stick to speed limits?

Actually the 10% thing is a rule.

EDIT:
Quote:
"Vehicle construction and use regulations require a vehicle speedometer accuracy to be in the range of -0->+10%. The implications are that it must never under-read - for obvious reasons - but may over-read. As the cost of manufacturing a speedometer with -0% error would be very costly they all over-read by a few percent without exception. Even if speed is measured correctly the display may not be accurate, so a speedometer error is allowed. Because of this, the Association of Chief Police Officers (ACPO) have an official formula for calculating a speeding offence. It allows a leeway of 10% plus 2mph."

Its not a rule, you're confusing speedo accuracy against the actual speed he was doing.

Don't believe everything that you read on Yahoo! Answers.

Crown Prosecution Service wrote:
The Association of Chief Police Officers (ACPO) has issued speed enforcement policy guidance, which suggests that enforcement will normally occur when a driver exceeds the speed limit by a particular margin. This is normally 10 per cent over the speed limit plus 2 mph. It also sets guidelines for when it would not be appropriate to issue a fixed penalty notice but to issue a summons instead (see below). Note that these are guidelines and that a police officer has discretion to act outside of them providing he acts fairly, consistently and proportionately.

It wasn't off Yahoo Answers, I dont go there. Laughing

It was off some proper site but I forget which, I quoted it elsewhere a while ago and re-took it from there.

I'm sure it's right, I recall looking really into it so that I wasn't posting wrong info on the basis that whoever was reading it didn't take it as gospel and lose their licence..

Edit; from Pepipoo (most legal & clear forum we have):
Quote:
UK law requires that a speedometer be accurate +/- 10% at 30 mph. The law does not specify a tolerance for any other speed.

This has been superceded by EU legislation that requires a speedometer not to underread at any speed.

To allow for tyre wear and manufacturing tolerances most manufacturers design in a 5- 10 % overread.
