VSB14 explained: the national code behind every state scheme
Vehicle Standards Bulletin 14 (VSB14) is the national code of practice for light vehicle modifications in Australia. It is not law by itself — each state and territory adopts it through its own scheme, such as VSCCS in NSW, VASS in Victoria and the Code of Practice in Queensland.
What VSB14 actually is
VSB14 is a national code of practice for modifying light vehicles, published to give certifiers and owners a consistent technical baseline. It is important to understand what it is not: VSB14 is not itself legislation. Each state and territory gives it force by adopting it into their own scheme, sometimes with local additions and exclusions.
That is why a modification can be textbook-compliant with VSB14 and still need a jurisdiction-specific approval.
The sections you will actually meet
| Section | Covers | Typical work |
|---|---|---|
| LA | Engines | Engine swaps, capacity increases, forced induction |
| LG | Transmissions | Gearbox conversions, bellhousing and tailshaft changes |
| LH | Brakes | Big brake kits, master cylinder changes, bias changes |
| LK | Seats & restraints | Additional seats, racing seats, harnesses, anchor points |
| LM | Fuel systems | LPG conversions, fuel cells, surge tanks |
| LO | Body & chassis | Aero, widebody, lighting, accessories |
| LS | Suspension & steering | Coilovers, lift kits, ride height, steering conversions |
How to use it as an owner
You do not need to read VSB14 cover to cover. You need to know which section your modification falls under, because that is the language your certifier, your state authority and your insurer all speak. Recording the VSB14 section against each modification in your build record turns a vague list of parts into something a certifier can assess quickly.

Frequently asked questions
Is VSB14 the law?
No. VSB14 is a national code of practice. It becomes enforceable through each state and territory's own scheme and regulations, which may add local requirements.
Does complying with VSB14 mean I don't need certification?
No. VSB14 sets the technical standard; certification is the process of having a licensed certifier or signatory verify and record that the standard was met.
