Australia’s ZERO TOLERANCE speeding law in action ($146 fine issued for 1km/h over the limit!)

We were recently sent in this picture of a speeding fine, showing an unfortunate chap who copped a fine for 61 in a 60 zone. Talk about zero tolerance! We certainly hope this person fights that fine, as it would appear to state the method by which they measured his speed was “Follow Speed”. According to our sources tailing a vehicle should never be relied upon for speeds within this close to the speed limit. (read more)

We had a lot of discussion over the fact that people seem to think that their speedometers only need to be accurate within +/- 10%, however this law was changed in 2006, whereby a vehicles speedo can read 10% plus 4km/h LOWER, but NEVER higher. However, if the vehicle in question was older than 2006 model, then surely then appropriate leniency should also be applied. What do you think?

This also poses the question, how accurate does the police car’s speedo have to be? Technically according to the ADR’s, it COULD be reading 10kph HIGHER than actual speed..

Mr Cassidy was driving a company car on a delivery and is not convinced he was 1km/h over.

Last night, police were unable to say what triggered the change but added officers would continue “scrutiny of all road users” to ensure safety of the public.

“Kirwan police will continue to maintain vigilance towards road safety through the Christmas break and into the New Year,” they said.

 

We have included an extract of this law from the Australian Design Rules below:

[extract from RACQ Australia]
The accuracy of vehicle speedos is covered by Australian Design Rule 18. Until July 2006 this rule specified an accuracy of +/- 10 percent of the vehicle’s true speed when the vehicle was travelling above 40km/h.

That is, at a true vehicle speed of 100km/h the speedo was allowed to indicate between 90km/h and 110km/h.

An odometer accuracy of +/- 4 percent was also a requirement.

From 1 July 2006 newly introduced models of a vehicle available on the market must comply with ADR 18/03. Also, from 1 July 2007 any newly manufactured vehicle (excluding mopeds) must comply with this rule.

This new rule requires that the speedo must not indicate a speed less than the vehicle’s true speed or a speed greater than the vehicle’s true speed by an amount more than 10 percent plus 4 km/h. Significantly, this change means that speedos must always read ‘safe’, meaning that the vehicle’s true speed must not be higher than the speed indicated by the speedo.

That is, at a true vehicle speed of 100km/h the speedo must read between 100km/h and 114km/h. An alternative way to look at it is; at an indicated speed of 100km/h, the vehicle’s true speed must be between 87.3 km/h and 100km/h.

Significantly, this change means that speedos must always read ‘safe’, meaning that they are not permitted to read lower than the actual speed of the vehicle.

Additionally, there is now no requirement to have an odometer, and therefore there is no accuracy requirement.

This change was made to align Australian vehicle rules with those already in place in Europe.

Note that some vehicle manufacturers chose to comply with the new rule before 1 July 2006. This is acceptable.
