No. Squatted trucks—vehicles modified to sit lower than manufacturer specifications—are illegal in Australia under national vehicle standards. The National Transport Commission’s 2023 Vehicle Standards Bulletin 14 explicitly prohibits modifications that alter ride height below original design limits, citing safety risks. State-based enforcement agencies, including Victoria’s VicRoads and NSW’s Transport for NSW, actively penalise non-compliant vehicles, with fines up to $2,200 and mandatory defect notices. Recent 2026 draft amendments to the Road Vehicle Standards Rules tighten scrutiny on aftermarket suspension alterations, requiring engineering certification for any ride height reductions.
Key Regulations for Squatted Trucks in Australia
- National Standards Violation: Under Vehicle Standards Bulletin 14, squatted trucks breach the Australian Design Rules (ADR 43/04) for vehicle stability and braking performance, as lowered suspension compromises crashworthiness and handling.
- State Enforcement: Transport agencies in Queensland (TMR) and South Australia (DIT) mandate roadworthy inspections, where squatted trucks are classified as “major modifications” requiring pre-approval from an approved certifier under National Code of Practice for Light Vehicle Construction and Modification.
- 2026 Compliance Shift: Proposed amendments to the Road Vehicle Standards Rules will introduce mandatory third-party engineering sign-off for any suspension lowering exceeding 50mm from original height, aligning with EU-style vehicle conformity assessments. Non-compliance will trigger vehicle registration cancellation.
