AI-generated summary
Gregory Stephen Bonanno, 22 years old, died when his vehicle skidded off a country road with a freshly resurfaced section and collided with trees. The accident occurred on a road with loose gravel from recent repair work. Contributing factors included probable speeding by the driver and inadequate warning signage. The 'Loose Stones' sign displayed did not include speed restrictions or 'Slippery Surface' warnings that would have been appropriate given the hazardous loose surface conditions. Multiple road users that day experienced loss of control on the same patch. The coroner found that updated signage protocols (requiring 60-80 km/hr speed restrictions) and more rigorous risk assessment processes would have been appropriate and potentially preventable. Training gaps for road supervisors regarding traffic management standards were identified.
