Court-experienced expert witness. Senior Road Safety Auditor. 25+ years across road, vehicle and driver.
Forensic crash investigation. Road safety engineering. Independent expert reports for Victorian courts, government, and fleet operators.
Unique Vantage Point
Court appointments give TVL direct insight into fatal crash causality that routine investigation rarely surfaces. Every case builds a growing body of knowledge about why road users behave the way they do. And what the system could do differently — insight that informs TVL’s road safety engineering, fleet safety advice, and CPD for legal practitioners.
Across the Whole System
Most practitioners specialise in either the road, the vehicle, or the driver. Johann Tay holds authoritative expertise across all three — and the legal and human factors knowledge to connect them. In court, this means causal factors that fall outside a narrower expert’s brief can be identified and presented with technical rigour. In policy and fleet settings, it means advice that accounts for how system elements interact, not just whether each meets its standard.
Built on Real Cases
TVL’s work is grounded in actual criminal prosecutions, civil litigation, infrastructure audits, fleet deployments, and research publications — not generalised consultancy. When you engage TVL, you engage 25 years of hands-on experience with the road transport system in its full complexity — and a practice that keeps pace with technological change because it understands the system, not just the standards.
