The Heavy Vehicle Registration Assessment Scheme (HVRAS) accredits persons to inspect and measure
motor vehicles more than 4.5 tonnes Gross Vehicle Mass (GVM) and trailers more than 750kg Aggregate
Trailer Mass (ATM) prior to registration.
This is to ensure that these vehicles comply with:
- Dimensional limits
- Approved load sharing axle systems
- Safe tyre limits
- Vehicle identifiers (engine number, VIN, chassis number, modification plates).
