When it comes to the law, ignorance is no defence.

As far as the police are concerned, the person behind the wheel is responsible for any and all transgressions associated with the towing setup.

Unlike a heavy commercial vehicle, such as a transport truck, in which there is a chain of responsibility from the driver to the person who loaded the vehicle to the owner of the vehicle, compliance responsibility for a light vehicle always rests with the driver.

Did a mate lend you the van and vehicle for your family holiday, assuring you that all was fine? Doesn’t matter.
