- Ticket for doing 61mph!!!!!
Link to the speed limits.Posted 9 years agobuzz-lightyearMember
some will be dead accurate, and some over-read by as much as 10%.
I did some experiments with my two Hondas, comparing speedo readings with GPS. One closely matched the GPS, the other was about 10% lower.
Never having had a van, I didn’t know there were different limits. Interesting.Posted 9 years agomike_checkMember
I used to work in the Magistrates and had to deal with this kind of stuff day in, day out. Anything you do to be awkward (asking for calibration, don’t know who was driving etc) will most likely work against you, best thing you can do is send an accompanying letter querying why you are being penalised for such a small infringement. Be polite and act a bit upset about being ‘in trouble with the law’ (even though you know it’s minor and no copper will ever speak to you about it let alone cart you off to jail!)
They will then explain, if applicable, the rule regarding being in a van, and most likely, due to the circumstance offer you the awareness course which leaves you to pay costs for the course, but no points on your licence.Posted 9 years agoIAMember
I’m sure all the folk posting about speedo’s reading over etc are right – but all thinking GPS is accurate? It’s not. Or rather you can’t say it is without information on the errors, the constellation of satellites in use and the filtering algorithm in use by the satnav software. GPS is no-where near as good as most people think, even very, very expensive DGPS systems. It’s a lot of clever filtering and fitting algorithms that make tom-toms and the like seem as good as they are. For average speed over a reasonable distance the GPS will be very good however. But to get a better idea what your speedo reads, you’re probably just better getting a stopwatch and using the blobs on the road like the police. (disclaimer: i don’t know what algorithms etc tom-toms use, it’s probably a trade secret. But i have worked with processing data gps systems etc before).
Oh, and all the people debating it – the issue was he was in a van, so was done for being 11mph over – more like 20% not 10.Posted 9 years agobuzz-lightyearMember
“but all thinking GPS is accurate”
I think you can assume consistency in how the system and device works from run to run. Although it depends on the number and relative velocity of the satellites at the time, but if you do a few runs and eliminate the peaks and troughs this variation is small compared with what you are measuring.
Comparing all the runs, my Civic was consistency close to the GPS reading, while my Accord was consistently and noticably below, about 5mph below at 50mph.
Sadly for us, radar guns are very accurate at measuring your approach velocity, assuming they don’t get jammed.how radar guns workPosted 9 years agoWTFMember
There is also the old “sorry, it’s a company vehicle, it could have been any one of 5 drivers driving that day, so without a photo of the driver I couldn’t tell you who it was” excuse… Seen that one work for a lot of people!
That doesnt work anymore AFAIK as you have to keep a drivers log ? and if no one admits to the offence then the MD would be prosecuted.Posted 9 years ago
That isnt going to happen is it ?IAMember
“I think you can assume consistency in how the system and device works from run to run.”
That’s precisely what you can’t assume (unless it’s in the same place at a similar time, with a similar view of the sky). As I said it depends on the constellation of satellites in use. The accuracy varies along different planes dependant on this.
To give a (very) simplified example, imagine all the satellites are in a line, and the only method used for position is triangulation. You get very low error in one axis (across the line), and very high in the other (along the line).Posted 9 years agoBearBackMember
Maybe its an urban myth but I thought there was a bit of leeway to allow for speedometers that aren’t exact.
Spedo’s can read incorrectly.. but spedos have to be calibrated to only read fast within tolerance.
A speedo cannot read slow.. i.e if you are travelling at 60mph, your speedo cannot read anything below 60mph, it can however read above 60mph (infact anything over up to 15%.
This info is as per the kit car Single Vehicle Approval compliancy.
So, you actually have no excuse if your speedo is wrong.
I got done by a private speed camera van in a 50.. mighty annoyed as it was parked in a hard shoulder on a dual carriage way, but I didn’t have the piece of mind to go back and get a photo of it(illegally parked?)Posted 9 years ago
Anyway, I believe they sell their fines to the police, so its in their interest to sell every speeding offense whether it be +1mph or more.
Private speed camera vans are worse that static speed cameras, they don’t make considered judgment and they ALWAYS have film. 😮
I’d also question when the camera in question was last calibrated. Basically if I was getting fecked for the sake of 1mph I’d want to know that ALL their equipment and procedures were spot on first. I don’t believe in the arguement above that it gets peoples backs up when its a citizens right to know that he is being prosecuted fairly. Sorry if that creates more administration for you poor deary’s.Posted 9 years agoKitMember
hora, keep up! He was driving a van, therefore he’s been done for 11mph over the legal speed limit, not 1mph.
Steve, I passed that van too last Saturday, about 8:30ish. A car coming the other way flashed their lights to warn me (also illegal) but as it was I caught up with a guy doing 50mph so was well under.Posted 9 years ago
You cannot use ignorance of a law as an excuse for breaking that law.
So you could drive the wrong way down a road and plead you did not know it was illegal because you had no insight of that law.

Jesus…so in my new Berlingo (notice how I had to put “new” in there?…cock!!), I’m limited to 50 on a normal road and 60 on a DC…****, why didn’t anyone tell me that before???!!!!
Yeah, I know it’s my responsibility, but you’d have thought someone in the dealership or one of my smartarse, know-it-all “mates” (having a rethink on each and every one of them now) who know it’s my first van after years of using an estate for work would have told me…”you do realise now Mr. Darcy, that you need to reconsider the speeds at which you’re driving”.
Thank **** for STW!!Posted 9 years agoPePPeRSubscriber
DeadlyDarcy it all depends on what its taxed as, my Kia Sedona weighs more empty than a Citroen Dispatch is bigger overall but is not limited to the speed limits.
A Berlingo has a maximum weight under 2 tonnes,
A Dispatch has a maximum weight of 2.6 Tonnes
Any commercial vehicle which has a maximum weight of over two tonnes is subject to the restrictions below.
50mph on A roads
60mph on dual carriageways.

I dont remember the van limits in the HC when I did my driving test.
I know that HGV’s are meant to be down at 40mph on single roads, but had forgot about vans being at 50.
I think basically you’re going to have to stump up the fine mate. If it was just shy of 60, you may have gotten away with it, but over it and its an auto-ticket so to speak.Posted 9 years agomiketuallySubscriber
I dont remember the van limits in the HC when I did my driving test.
They were there 15 years ago when I failed my driving test twice and they were still there 5 years ago when I passed my theory test.
I think there’s a lot of evidence for compulsory retesting on here!Posted 9 years agosockpuppetSubscriber
All this talk of speedo innaccuracy is a diversion. The offence is to break the speed limit, regardless of what your speedo says.
especially when your speedo was probably reading 66ish at the time, as discussed above, on a road where the op thought the limit was 60…Posted 9 years agoMarkSubscriber
There are individuals on this thread who are being typically awkward and belligerent. Smee.. you are treading a fine line. Change your attitude or expect mod intervention in your posts. That’s not just for this thread but for your standard of posts in general. Others need to start playing nice or I’ll personally step in and suspend your accounts under the negativity rule.Posted 9 years agoWipeOutMember
I know you probably think it a bit boring, but doesn’t anybody keep a copy of the Highway Code and read from time to time any longer?
Doesn’t mean you’ve passed your test, that you can’t continue to learn as a driver.
I hear lots of complaining about driving standards, and yet rarely hear of people trying to improve or better there own standard of driving.
Advanced Institute of Motoring is very helpful.Posted 9 years ago
