as far as I know. Reason being they are only there to police the defect.
Remembering cops don't actually have to prove a defect, just think. If a cop pulls you over saying your ride is lower than 100mm, he doesn't have to test it or get a measure out, he can just defect it, same with loud exausts.
If on this basis, if they were then allowed to fine you, it would be ludacris. Imagine a cop fines you for having your ride too low, you then go and get it checked an an inspection station and turns out the cops eyes were out an he has no idea.
You just cop the fine ? I think not.
or what if they fine you, defect you, and you don't get the defect cleared within the given time, not only would you have been fined but also lost your rego. Bit harsh eh.
I'd love to hear from anyone who has been fined for a defect :!:
