Coroner's Finding: Barber, Gavin John

55y · Male·head injury sustained in a single motorcycle crash

A 55-year-old man with multiple comorbidities (bipolar disorder, OCD, asthma, bronchiectasis, methadone dependency) died from head injury sustained in a motorcycle crash. He was riding 3 weeks after a previous motorcycle crash causing clavicular fracture. Toxicology revealed methadone, oxycodone, diazepam, olanzapine, and high-level cannabis use. The crash investigation identified contributing factors: the healing clavicular fracture would have impaired left-arm control during right-hand cornering; respiratory-depressant drugs compromised reflexes and reaction time. While crash speed was appropriate and conditions excellent, the combination of unhealed injury, polysubstance use, and reduced respiratory capacity created unsafe riding conditions. Clinical learning: patients with recent orthopaedic injuries, polypharmacy with CNS-depressants, and cannabis use require explicit counselling regarding activity restrictions and impaired judgment/reflexes.
