AI-generated summary
A 53-year-old experienced cyclist died after losing control of his bicycle on loose gravel left on a roadway during utility works. He collided with an oncoming vehicle on a downhill left-hand bend at Kingston Beach. Friction testing confirmed the gravel created ice-like conditions (friction coefficient 0.17). Risk assessments and signage complied with Australian Standards but failed to specifically address cyclist vulnerabilities. Other cyclists reported being surprised by the gravel despite signage. The coroner found that while signage warned of 'rough surface', specific warnings about 'loose surface' and debris, or cyclist-specific hazard signs, may have better communicated the danger. Closure of the route to cyclists or increased debris removal during works could have prevented this death. The case highlights inadequate consideration of vulnerable road users in temporary traffic management planning.

Error types
Contributing factors
- loose gravel and road base dispersed on roadway from excavation works
- low friction surface conditions equivalent to ice (friction coefficient 0.17)
- inadequate risk assessment specific to cyclists as vulnerable road users
- signage warning of 'rough surface' rather than 'loose surface'
- lack of cyclist-specific hazard signage despite known vulnerability
- absence of alternative mitigation strategies such as road closure, enhanced debris removal, or cyclist-specific warnings
- downhill approach into left-hand bend with gravel spread across the lane
- roadworks on a commonly used cyclist route without specific cyclist safety planning
Coroner's recommendations
- In circumstances where road works or road conditions pose a hazard to cyclists by the presence of debris on a road surface, warning signs advising of a loose surface be used.
- Risk assessments for roadworks should specifically consider the impact of roadworks on cyclists as a vulnerable road user, in addition to other road users, and identify risk mitigation strategies appropriate to each of the categories of road users.
