Yeah, so if the error is allowed at 10% then surely it is 5% either side of the maximum allowable.
Therefore if traveling at 106 in a 100 zone you would be 1KMpH over the allowable margin wouldn't you?

by the book

the ADRS are written such that the error on the speedo may only be over your 10% is over speed IE your speedo may say 110 and you are actually doing 100 no speedo is permitted to read underspeed as in you are doing 100 and the speedo reads 90.

you can be booked for 1KPH over the limit but the general rule of thumb is +5 or +10%. There was a spate in 01 in sydney where the cops blatently advertised their presence on every road leading to a school and then booked everyone caught doing over 40kph and no-one got out of it, they even went to the extent of taking out an ad in the district paper the week before.


IF you have some types of cruise control you can use that to get out of it PROVIDING you can satisfactoraly prove you set it correctly.

The current ADR prohibits any under-reading:
"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 ² (V1 - V2) ² 0.1 V2 + 4 km/h." This formula means that the vehicle's actual (true) speed must not be greater than the displayed speed.
The displayed speed is permitted to be greater than actual speed by up to 4kmh plus 10% of actual speed. So that means that if your car's actual speed is 100kmh, the displayed speed is permitted to be anywhere between 100kmh and 114kmh.

Prior to July 2006 the ADR allowed ±10%. This means that new cars sold prior to 1 July 2006 could comply with the ADR even if the speedo under-read by 10%. Despite this being theoretically possible, due to the testing procedures and the reasons stated below it is unlikely to ever occur in practice.
The reason the ADR are relevent to the debate is that some people argue that if the ADR allows cars to have speedos that under-read by up to 10%, then surely our road laws must also allow 10% tolerance. Therefore, the argument goes, we should not be fined if we travel at 110kmh in a 100kmh zone. Such a situation would be quiet generous to motorists and would make it impossible for anyone to allege that they were mislead by their inaccurate speedo.
One problem with this argument is that it ignores reality. It assumes that speedos are under-reading by 10% when the truth is most speedos over-read by about 3%. So in effect, it is allowing the majority of motorist the opportunity to drive at 10% above the speed limit. If the speed limits are there for a reason, then they would all need to be reduced by 10% to counter the effect of motorists increasing their speed above it.

Clear as mud :o:o

I knew I was correct (at least for pre-06 ADRs) because it was challenged in Victoria a while back - don't know the outcome - other than the Vic governmemt said it was the responsibility of owners to know the error in their speedos and take that into account - the "defence" said that then that should be legislated - however as pre 06 cars were permitted to have a 10% error it was unreasonable to book people within 10% of the speed limit - this may have even prompted the change in ADR requirements.

Garry

all of that is why you should let engineers make rules and not beurocrats.

whats going to get super interesting is when the new breed of GPS corrected speedos comes out......

If you are on the road and you can't tell that your vehicle is doing 106 when all the rest of the traffic is doing 100 then really are your observation skills sufficient for you to be doing 100 anyhow ?

What annoys me, is comments like this......

Especially the ones that read speed signs and "adjust" your vehicles speed to comply....

I'm waiting for GPS with calibrated maps of speed zones and user selectable alarms - this will be a good compromise for the user to know whats what.

That said, lets face facts, everyone knows when they speed but it is human nature to push boundaries - when we get caught the natural reaction is to find a scapegoat other than ourselves to blame. IMHO, a calibrated camera is working within it's operating parameters. If you are speeding and you get caught, it aint the camera, its you at fault. Blame the law makers for being unjust, but it remains the law until changed - live with it or move.

PS - my missus got done for 21km over 2 weeks back... ouch...

Why?

He's correct is he not?

Speeding fines, parking fines etc... are all voluntary taxes...

So you've never travelled over the speed limit, involuntarily or not:eek:
