Cool. thanks for that. i will keep that in mind. As i drive a truck, i am supposed limited to 90kph, so next time you are held up on an open road at 90kph behind a truck, don't get grumpy - just remember that its following your advice and not speeding.
I have found that highway patrol, police, etc generally are happy with trucks going up to 100kph. Im arguing the fact that i wasn't speeding. Did you read the detail in the post!

Yes I did read the post, but like every story this is your side!. Yes most people driving do speed from time to time, and yes if you stay to 90km I will pass you more easily. Cheers

If you dont have EROAD or other built in GPS yet- you should consider what other "problems" handing that sort info over to the "gods"may cause, if you- you know "work long hours" or the GPS readings dont match the "book" they will pick that up to and it can open a big can of worms. I have a simple handy cam setup in my truck, it records continuously and I can also pull the cam down and record the "gods" doing their inspections, they pull their head in then, belive me. Way better picture quality than those other ones like on tv show, I have large memory card, 32 gig is 11hrs continuous footage, just need an inverter for power supply, and a gps suction cup holder to mount it to windowscreen simple as, and the footage is yours not your bosses. About $500 all up so really worth it and I have the camera for home use to, had it 2 years and wont drive a truck without it now, wish I did it 10years ago, when doing wide and heavy loads like we do ALL the muppets come out of the woodwork on the road, atleast my ar5e is coverd.

You don't need to calibrate a GPS unit, they are accurate to no less than 9m. The triangulation it uses is more accurate than the callibrated speedos in the cops car. The signal strength won't affect the units accuracy -either the unit has enough to log or it doesn't!
I work for Navman Wireless (commercial units) and if you dispute this in court you GPS logs will stand up. We use the speed and also positioning to make sure the truckies get back their on road tax which is also accepted by the government as a "accurate and proven" method.

As already stated, and is correct you cannot submit the GPS log as evidence as the unit has not been officially calibrated. It may assist in giving you an approximate location but that is all you can do.

Distance is completelydifferent to vehicle speed. And they will not stand up in court if used trying to determine speed.

Actually in physics yes, how the GPS units track it no it is no different than position. Again I work for a GPS company YOU CAN"T CALIBRATE the unit you can only get more "accurate" map data. good luck trying to wrestle that off the American military.

Obvious you do not know about light aircraft pa 38 pa 28 s pa18 etc,most do not have dual instruments

Aircraft normally only have a second set of instruments if they have been built with the intention of doing commercial passenger operations under IFR. Otherwise it is just a waste of money at at several thousand dollars per instrument.

Hmmm.so if this goes all the way and you have to submit the trip details as evidence, they can drop the charge to exceeding by 13kph and your defence is back to your word against theirs. Not saying don't defend it, I think you should, just saying it could be a bit of a double edged sword.
Still doubt you'll get the ticket.

So much missinformation in this thread, I will clarify a couple of points that stood out by other posters. 1. Parallax, where the passenger can not accurately see what speed the driver is doing from where he is sitting - In most vehicles that is true however in the newer commodores that the cops have there is a digital speed readout in the center of the console which displays the speed the driver is doing, so no needle confusion there.
2. CVIU was probably non sworn and will get someone else to write the ticket - CVIU is a sworn position so have the power to write and issue tickets, no sworn cop would be stupid enough to take someone elses word that an offence occurred and write out a ticket for them thats just asking for a defended ticket.
3. The mention of lasers, no evidence etc - What would of happened was the CVIU would have followed you matching your speed with his and taken the reading off of his display, all police cars have calibrated speedos which can be used evidentially in court as a speed measuring device.
4. GPS - while your unit may have said you were doing xxxkm/hr how can you prove it, because as far as I know your off the shelf gps don't record every how fast you go, only the fastest the unit has been, and it is not a calibrated speed measuring device and can not be used in court.
My advice is either pay up or if you really feel hard done by and are prepared to take a day off work to go to court and plead your case then do so, it will only be jp's court and the burder of proof for the police is higher than yours so all you need to do is create a small amount of doubt and they might let you off, and if you do get convicted then you get an extra $130 court costs on top of the fine.

No, distance is not different to speed - speed is distance divided by time. The time too is accurate, as that is how GPS works. Each transmission, from each satellite, identifying itself has a time stamp.

thats rubbish. if you have distance and time you can calculate speed. the laws of physics dont change.

one one alpha this is zero Bravo,
depends on the gps model methinks. I know mine has the fastest speedand when it was recorded. reset it for each trip an then it starts the log again.

I think the issue here is that alleged offence took place less than 1km from the 100kph zone - I had thought the required distance to speed match was further than this, do you know!
I can categorically assure you this is incorrect. I have used a truck GPS to defend two charges of not wearing seatbelts by a driver and his assistant, using nothing more than the information provided by the GPs unit, including the speed log, being able to prove that the truck had not exceeded 47kph in the hour previous, and had not left the inner city. I was not asked asked to prove calibration, and neither would I have expected to have been.

thanks guys. again, some goo information, and a bit of a result. In the mail today was a fine for not carrying/presenting drivers license. no mention of speeding at all.
I failed to mention the lack of carrying license in the first post, as it was something i immediately admitted to, to them, as is had left my wallet in my van at the depot in the morning. That, i was expecting a fine for, and had no bearing on the alleged speeding.
the gps i had purchased is a uniden IGO50, 24/12v. it has a trip monitor function - I'm still learning it, but it brings up a days/trip summary, including max speed, average, driving time, stationary time, max alt, etc etc.
They either must have been trying to bluff me into admitting to speeding, or something. but end result, no speeding ticket. The other fine, i was in for, and not disputing. thanks for every ones input.

thank you for that link,has anyone else dealt with this camera company as seems very cheap for what it is considering the ones promoted on that programme with Ewen Gilmore are about 600 bux am looking at getting one also due to a similar reaction from the boys in blue

Not trying to flog a dead pony here, but I'd be inclined to contest that too! Police have publicly stated that where a driver is not doing anything wrong they will not pursue the mandatory carriage rule.

Wouldn't that one be as well by the time you factor in currency and freight!

Sorry to pee on your parade but they have digital mode too; easy to see from passenger seat.
