| Upcoming changes to the PBS Directional Stability Under Braking (DSUB) standard from 1 July 2026
From 1 July 2026, the Directional Stability Under Braking (DSUB) standard is being updated to modernise braking requirements under the Performance Based Standards (PBS) scheme. These changes only apply to vehicles entering the PBS Scheme for the first time from 1 July 2026. These vehicles are:
- Newly built vehicles, and
- Existing in-service vehicles entering PBS for the first time.
Vehicles that were PBS-approved prior to 1 July 2026 are unaffected, except for limited connectivity requirements when operated in combinations with DSUB-compliant vehicles.
The revised DSUB standard will improve safety outcomes by increasing the use of advanced braking and stability technologies. The NHVR website has additional DSUB Industry Information and FAQs available. | | | | | |

| New digital identity verification system in NHVR Go
Protecting customer information is important to the NHVR, and one of the steps to protect our customers is to require users of the NHVR’s registration services to use an online verification service.
NHVR Go users are advised the NHVR’s online digital ID system will be provided by greenID. The system will offer a similar service to the former service in use, Australia Post’s Digital ID, offering a secure, safe and simple way to prove who you are online.

| Don’t spread fire ants - cover your load
NSW DPIRD is reminding industry to ensure high-risk materials sourced from fire ant infested areas in Qld and NSW are stored and transported under preventative conditions until they reach their destination.
Known carriers such as turf, soil, mulch, hay and potted plants, must be securely covered, stored off the ground or on treated hard surfaces, and remain covered during transport into NSW. Read the current Emergency Order and understand your duties.
The NHVR has supported NSW DPIRD operations to mitigate fire ants spread via heavy vehicles, machinery, and agricultural materials.
For more information visit www.dpi.nsw.gov.au/fire-ants or call 1800 680 244.
