hey everyone, i recently got a new job and i have to drive pass around 3-4 speed camera twice a day.

so this is making me a bit edgey so i just want someone to help me clarify:

1, how much km do u have to go over the actual speed limit until you get snap

2, how long will it take for them to send a fine letter IF i did get caught

-pete

1. usually over 10% of the speed limit, ie over 88 in 80 zone

2. not really sure on this but i think someone mentioned 6-8 weeks or something..

I've heard of many cases where they've been set to less than 10%.

DO NOT speed past them.......

From big-ass trips... speedos are usually set to be lower than the speed you're doing.... If you use a nav. unit, it always displays that you're travelling slower than what the speed ostates (they might not take into consideration contours however)... But the speedo-checks on highway to melbourne registered same speed as GPS; which was at least 7km/h under what the speedo read. - so don't get paranoid, but don't exceed the limit. Driving instructors recommend 3km under speed limit to do driving tests :blink:

I thought fines always come within 2 weeks?

Keep in mind that if is IS 10%, it's still not going to be a good measure, due to inaccuracies in your speedo, the camera etc. Just do the speed limit through the camera.

thats when a pfc commander comes in handy :blink:

If you know where they are why would you speed past them?

:blink:

like a few people have said, speedos in cars generally read about 5km/h over what you are doing. so if the speedo says 100 youre doing 95. so if you go through a speed camera on, or even slightly above the limit, you should be right.

cops with radar/lidar ive heard need to give a 10% leeway. add into account that your speedo is high as well..

many times ive been in a 100 zone, with the speedo reading 110 to 115, and a cop has been there, and i havnt been done.

10% are you kidding me? lol. It's more like 2 or 3km/h. so 63 in a 60 zone will most likely see you booked, as will 103 in a 100 zone. I have no idea who came up with this 10% theory, but it's bullshit.

your theory is no better

it's definiately not 2-3km/h

afraid to say.. not a good year for me :)

Just curious to know, do policemen have a Flash on their Radars?? or any other speed recording device (Laser)? etc

I was doing abt 111kmh in a 100 zone :D:( silly me,

I think i saw a flash from behind some trees and an un marked commodore parked some 2km down on the M4

can't be sure if it was me, as there were a few other cars around me doing the same speed...

but then again, i can't even be sure if it was a police flash or some blue light i saw through the trees in a factory or sumthing else :D ..........

dam , sooooo anxious. hope i dont get anything in the mail.

Most radar's do not have a flash, if the radar operator sees someone doing high speeds they would radio the chasing car (in this case I assume it would be the unmarked commonwh0re parked 2km down the road) telling them that x person is speeding and to chase em down.

However there are new radar setups where the radar is on the ground and the camera is behind it. They need to have a good lock on ~3secs then takes a photo immediately. Quite easy to notice this.

I think all police officers are being currently trained to operate radars, all HWP's know how to use radar's already.

As for your case, ADR's specifies 10% tolerence for speeds, so maybe you are being paranoid.

from

http://rvcs-prodweb.dot.gov.au/files/ADR%201803.pdf

5.3. The speed indicated shall not be less than the true speed of the vehicle. At the test

speeds specified in paragraph 5.2.5. above, there shall be the following relationship

between the speed displayed (V1 ) and the true speed (V2).

0 ≤ (V1 - V2) ≤ 0.1 V2 + 4 km/h

The equation means as follows:

95 Being Indicated speed 90 being true speed.

0 <= 95 -90 <= 90*0.1 +4

0 <= 5 <= 13

So there for Indicating 95 but going 90 is in the acceptable range. Were are as

110 Being Indicated speed 90 being true speed.

0 <= 110-90 <=90*0.1+4

0 <= 20 <= 13 Which means its not acceptable.

So the allowable difference depends on the speed the car is actually traveling.

Put easier, your indicator must NOT be showing a slower speed then the car is travelling, and it must not indicate more the 10%+4km of the true speed

So In a 60 zone, your indicated speed must be between 60-70 to be ADR approved.

In a 80 zone, 80-92

In a 100 zone, 100-114

In a 110 zone, 110-125

10% are you kidding me? lol. It's more like 2 or 3km/h. so 63 in a 60 zone will most likely see you booked, as will 103 in a 100 zone. I have no idea who came up with this 10% theory, but it's bullshit.

You are wrong as far as NSW goes ( as we speak, plans are in place for much less leway) but you are correct as far as VIC goes, 63 in a 60 zone ,84 in a 80 zone and they get you. This is speed cameras only, its up to the cop if its a none camera speed trap. What gets me in the case of VIC is the fact that the equipment they use to measure speed has a plus or minus 3% accuracy according to manufactures guidelines, if I was booked for doing 63 in a 60 zone I would defend it in court and I would win everytime!!

yeah true. I still don't believe it's anything like 10% though. Someone please drive through a 110 camera at 122 and tell me what happens :P my guess is fine.

    • Hi all, Long time since I've posted here. Looking for some advice on what I can remove to further identify the cause of my issues.  I can move the passenger seat forward and back but the knob used to adjust the seat angle is pretty much free spinning, there's very little resistance.  Removing the side cover I can see that the chain is intact but the shaft for the adjustment spins without the gear attached to it moving.  What's my next step for disassembly here? Is this a common fault? Just being a little cautious as I didn't want to start removing bolts for a spring to fly out or something equally as stupid.  Cheers
    • Those above shitboxes, mediocre and above usually have a turbo strapped to them, hence the slightly higher octane is required.  
    • Hi all,   long time listener, first time caller   i was wondering if anyone can help me identify a transistor on the climate control unit board that decided to fry itself   I've circled it in the attached photo   any help would be appreciated
    • I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!
    • I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.
