Without prejudice to any other method of proving the relevant fact, if the fact that a vehicle was driven or a trailer was towed in a toll zone is relevant in proceedings for an offence against section 73(1) or for the recovery of a debt, evidence of that fact as indicated or determined by—
(a) a prescribed tolling device that was used in the prescribed manner; or
(b) an image or message produced by a prescribed process—
is admissible in evidence in any proceedings and, in the absence of evidence to the contrary, is proof of the fact.
