I was wondering about this post as I got a ticket some time ago, knowing I was going a tad fast I pulled over as soon as I saw the lights go on & the cop turning around. I had just looked at my speedo & GPS & both read 109, looked up & there was the cop. bugger! My surprise was when he ticketed me for 114. So while going down the southern motorway I made use of the roadside speedo check (5 x 1km signposts) & my odometer clicked over the new 1km every time, so my speedo is spot on. My concern is that the revenue collectors on the force (as I believe most are honest cops that want to make a difference) have no way of verifying that was my speed. What stops a cop from clocking someone, ticketting that person, leaving the unit on lock & getting another (or more) with that same reading!

Yeah because people are known to always be truthful.No wait, thanks for that adam and eve.

I think thats been an issue before and easy one to sort. Is the speed they show you time stamped etc, would hope so. There will be ways of proving it if they were doing this.

No. Your odometer is spot on. That's not the same thing.
At 100km/h it takes 36s to travel 1km. That's what you need to check - the time.

No, it's not timestamped. There is no way to prove where, when or whom gave the displayed reading.

Thats a bit piss poor then. They are a computerised thingy so you would think it would have a time ref.In that case everyone could go to court and say "prove it that speed was 5 hours ago by someone else".If they cant time stamp it it makes a joke of the whole thing.Although the one I commented on was a patrol car other speed camaras are time stamped arent they!

Camera are - mobile and fixed.

still works off your g/box final drive so if one is correct then the other will be too

So they eagle, hawk, budgie or whatever they nab you with are not, just the camaras!

Another rubbish post.might pay to do some research before you post again.

an interesting read for OP
If I wasn't speeding, how can I challenge/beat a speeding fine!
If you have been booked for speeding, and you were, then you should face the music and cough-up.But what if you weren't actually speeding!
Remember that when you are pulled over and booked for speeding, the incident is alleged??

Stalker are the mobile microwave of choice here does not. Kustom Hawk and Eagle are very old. LIDAR (LASER) does not.
Autopatrol SP-200 (fixed) and PR-100 (mobile) and the newer digital mobile units operating on very low power K-band all have timestamps.

Whatever. I've forgotten more than you'll ever know.

Incorrect.

try changing your diff ratio (or even tyre size) & see if one changes & not the other

Saying they operate off the same gear set and that if one is correct they both are are two different things, particularly given that the manufacturers build in an error.
My analogue speedo reads roughly 5kph high, but of I hold in the clock button I briefly get a correct digital speed on the clock display. So it's not that the car doesn't know how fast it's going (so therefore the odo would be wrong), it's that they choose to display it incorrectly on the SPEEDO.

That's a completely scenario different to saying they are both calibrated the same - they're not. That's like saying if you drive faster they also both indicate correspondingly faster so they must both be equally accurate.
whqqsh,

Im not saying they are both calibrated the same, its just that one is driven off the other. ok try this, cut your speedo cable & see if one still works without the other

It will increment the odo at 100Km/h.
tonyrockyhorror,

It doesn't matter that their source is the same - the readings they give are independent of each other. When the odometer fails, the speedometer can still work and vice versa.
You were concluding that given your odometer is accurate, your speedometer must be. This is the point I was refuting. They do not depend on each other.

80% of drivers, where are you from pal !

99% of the time it is (or rather within industry settings), also confirming one with other isnt a bad idea, especially when it confirms a GPS reading. Otherwise we should do away with those useless roadside checkpoints that prove nothing huh!
tonyrockyhorror,

I my experience, speedometers read a constant 5% fast while odometers are pretty much spot on.
I don't know what roadside checkpoints to which you are referring.

You need to look at strict liability offences, this is one of them. Speeding has nothing to do with intent, its a strict liability offence.
