If they're not driving the vehicle, or parking it in public, then no problem. If they are and get pulled over and checked then things are likely to get fairly expensive.

 

 

right, so nothing happens

 

When I got a speeding ticket in a diesel van, the police officer got me to display the ODO reading and noted it down. So my understanding it that is it standard practice for every police stop on a RUC vehicle.


There are fines for not displaying / carrying:

And steep fines for providing materially incorrect information (i.e. start km):

There is also a whole process for an Assessment of unpaid road user chargers to be done and billed to the owner or operator of the vehicle (up to 6 years worth). I Imagine they would use the odometer readings logged at WOF's and points of entry to estimate what the odometer reading was when RUC's kicked in.

Should note that the RUC system includes enforcement is fairly mature. Evasion happens but it is generally via tampering with the Odometer, not skipping out on the whole scheme.

Would be super easy for the the government to use the vehicle ownership & RUC databases to get a list of vehicles requiring a RUC licence and don't have one, then feed it into their automated number plate readers.
