AI-generated summary
Christopher Stewart, a 48-year-old experienced drag racing driver, died from injuries sustained when his vehicle collided with a concrete safety barrier at South Coast Raceway, Victoria at 259.97 km/h. The initial impact pushed the barrier backwards, exposing a sharp edge that tore into the vehicle's left side causing fatal injuries. The barrier was inadequately supported by earth backfill (13% versus the required 70%) due to equipment installation for timing sensors. The ANDRA Track Specification Inspector's 2015 assessment was inadequate—he did not walk the outer perimeter to inspect earth backing integrity. The coroner found this failure to detect structural deficiency contributed to the death. Subsequently, ANDRA has updated safety specifications to require engineer certification and improved inspection protocols. Key lessons: comprehensive physical inspection procedures are essential; temporary equipment installations must not compromise safety barrier integrity; and safety standards require regular updating based on identified risks.

Contributing factors
- inadequate earth backfill support of concrete safety barrier (13% versus required 70%)
- earth backing removed to accommodate timing sensor equipment
- inadequate 2015 ANDRA Track Specification Inspection—inspector did not walk outer perimeter to assess earth backing
- lack of prescriptive structural engineering specifications in 2004 ANDRA minimum track specifications
- barrier shifted and separated on impact, exposing sharp edge
- timing sensor installation created structural vulnerability at critical barrier location
Coroner's recommendations
- ANDRA should obtain structural engineering advice in relation to minimum requirements for reinforcing safety barriers to provide sufficient support and structural integrity
- ANDRA should update the 2004 specifications and associated documents to prescribe engineer-approved structural integrity requirements as minimum standard for all ANDRA-sanctioned race tracks
- ANDRA should communicate amended specifications and safety inspection information to all ANDRA-sanctioned track owners and users and make the information available on its website
- ANDRA should undertake assessment and/or re-assessment of all ANDRA-sanctioned tracks within 12 months of commencement of new specifications to ensure all tracks meet new minimum standard for safety barriers
