AI-generated summary

Ronald Ellison (46) and Jacqueline Sylvester (40) were struck by a speeding vehicle driven by Brett Glenbar (BAC 0.147) who lost control while negotiating a curve on Chambers Flat Road, Park Ridge, QLD on 4 December 2009. Police had activated emergency lights to intercept the vehicle for speeding (recorded at 134 km/h in an 80 km/h zone), but Glenbar accelerated. The police vehicle pursued at 186 km/h to attempt interception. Glenbar's vehicle reached 188 km/h entering the fatal curve, lost control in a 'yaw', left the roadway, and struck the couple with catastrophic force. The coroner found no pursuit occurred under QPS policy (a non-pursuit matter), but noted the police vehicle's speed breached urgent duty driving policies. The deaths were instantly fatal due to extreme impact forces. Clinical learning: this case highlights how intoxicated driving, excessive speed, and loss of vehicle control on curves present catastrophic collision risks, particularly for pedestrians with no time to react.
