Several creative Australians have offered definitive proof that they received speed camera tickets when they were not speeding. For example, a milk truck driver accused of 73km/h in a 50km/h zone had his delivery truck tested on a dyno. It established a speed beyond 45km/h would be impossible. The same traffic camera snapped a photo of a speeding parked car, and witnesses have made sworn statements that they saw the camera flashing even when no cars passed. Another man, Geoff Nadin, was driving in a 70km/h zone when a camera flashed him. His speedo read 67km/h and he had all his passengers verify this. When he contested the ticket claiming he was doing 87, charges were dropped and a subsequent investigation found pavement sensors were faulty.

Article Excerpt:

Mr Nadin consulted the NRMA's
legal department before penning a lengthy letter of appeal including the
statements of witnesses. The fine was then dropped.

An internal investigation revealed a problem with the pavement sensor, or
piezo, that registered speed.

Any veneer about infallible speed cameras has been certainly stripped away in
Victoria.
