Invoicing for RUC with data from weigh-in-motion scales

Using data collected from weigh-in-motion (or in-road) scales, we’ll soon be able to identify RUC non-compliance 24/7.

From the middle of 2024, we’ll be invoicing for unpaid RUC using that data.

The weigh-in-motion scales work in tandem with roadside cameras, which capture vehicles’ number plates.

This technology takes us a long way towards levelling the field for the heavy vehicle industry.

The data we collect will enable us to better target non-compliant operators – those whose trucks are persistently overloaded.

We’re focused on recovering underpaid RUC, but will follow-up and take action when we see repeated overloading.

Weigh-in-motion scales an important part of Commercial Vehicle Safety Programme

The weigh-in-motion scales will be placed at each of the 12 Commercial Vehicle Safety Centres that will make up the Commercial Vehicle Safety Programme.

So far 2 safety centres have been built, at Paengaroa in Bay of Plenty and Glasnevin in north Canterbury. A 3rd, at Rakaia in south Canterbury, will open in 2024.

When completed, the 12 sites will monitor 10 million truck trips and cover 46% of heavy vehicle kilometres travelled each year in New Zealand.

We anticipate that when all 12 safety centres are operating, we’ll increase the RUC revenue we collect by about $10 million a year: money that goes into the Land Transport Fund to build and maintain roads and roading infrastructure.

Accuracy of weigh-in-motion scales

We're installing 2 weigh-in-motion scales in the road at each safety centre to make sure our data is accurate. 

We're also: 

  • having our data models and assumptions reviewed by an expert third party
  • comparing trips captured in RUC audits of operators with weigh-in-motion data
  • regularly comparing weigh-in-motion data with safety centre weighbridge measurements.
