Mechanical asphyxia in the setting of a motor vehicle incident (driver)
AI-generated summary
A 53-year-old truck driver died from mechanical asphyxia when his vehicle left a rural highway near a right-hand bend with poor road design. Toxicological testing revealed cannabis at 59 ng/mL (elevated concentrations). The driver also had severe coronary atherosclerosis with focal myocardial changes. Contributing factors included cannabis use impairing reaction times and vigilance, possible cardiac arrhythmia, excessive speed for road conditions, vehicle's high centre of gravity, and inadequate road safety infrastructure (missing advisory speed signs and barriers). The coroner could not definitively exclude cardiac causes but noted the vehicle was likely travelling too fast for the bend. While clinical assessment was not directly involved, the case highlights how untreated cardiovascular disease combined with substance use affects driving safety.
