Know your number plate

The roadside electronic sign may signal you to pull into the commercial vehicle safety centre (CVSC) by displaying your number plate.

You must pull in to the CVSC if your vehicle is flagged during screening.

You should know the number plate of the vehicle you’re driving. Ask your operator to have this information available in the cab, where you can safely refer to it.

What are heavy vehicles?

A heavy vehicle is any vehicle, including a bus, coach or mobile home, registered with a class of MD3, MD4, ME, NB, NC, TC or TD. These are generally vehicles that weigh over 3500kg.

Weight, permits and loading

The weigh-in-motion scales in the road comply with international standards and are accurate for screening purposes.

Heavy vehicles with more than one permit are screened on the permit with the highest gross weight.

The system measures the weight on each axle. If your vehicle is within its gross weight limit but is overweight on an axle, axle set or axle group, the system will signal the vehicle to pull into a CVSC.

Make sure your vehicle is loaded according to Vehicle Dimension and Mass (VDaM) Rule guidelines and, if applicable, your permit.

Vehicle Dimension and Mass Rule (2016)

What happens if you try to avoid the screening?

It you try to avoid the in-road technology it will be noted and recorded for further analysis.

You must stop at a CVSC if you’re instructed to. Not doing so can incur a $1000 fine.
