Cause of death
Head injuries - horse rider struck by a motor vehicle
AI-generated summary
A 31-year-old Japanese horse rider died from head injuries after being struck by a motor vehicle while crossing a public road with horses at dawn. Low light conditions (approximately 6:40 am, still dark) impeded the driver's visibility. The rider wore no high-visibility clothing, reflective gear, or lights; horses had minimal reflective markings. The driver had a blood THC level of 3 ng/mL within three hours of collision, which the coroner found on the balance of probabilities impaired driving ability to some extent. However, multiple factors contributed: poor visibility, inadequate rider safety equipment, and low light conditions. Since the death, the workplace has implemented mandatory high-visibility vests for riders, reflective horse gear, and sunrise-only work policies. The speed limit was reduced from 80 to 60 km/h. Key clinical lessons: THC impairs driving even at low baseline levels in regular users; psychomotor effects persist beyond subjective intoxication; workplace safety systems must be formalized, not reliant on verbal instruction.

IN THE CORONERS COURT COR 2020 001341 OF VICTORIA AT MELBOURNE FINDING INTO DEATH WITHOUT INQUEST Form 38 Rule 63(2) Section 67 of the Coroners Act 2008 Findings of: Coroner Simon McGregor Deceased: Takamasa Takeda Date of birth: 27 May 1988 Date of death: 9 March 2020 Cause of death: 1(a) Head injuries- horse rider struck by a motor vehicle Place of death: Thirteenth Beach Road & Blackrock Road, Barwon Heads, Victoria, 3227 Keywords: Motor vehicle collision, pedestrian, horse riding, road crossing, cannabis, THC
On 9 March 2020, Takamasa Takeda was 31 years old when he died from injuries sustained when a motor vehicle collided with the horse he was riding.
Takamasa was a Japanese national and had been in Australia for approximately nine months on a working holiday visa.1 During his time in Australia, he had worked for approximately six months at Cumani Racing Stables in Ballarat, then commenced work as a full-time track rider with O’Brien Thoroughbreds (Aust) Pty Ltd (‘O’Brien Thoroughbreds’) in January 2020.2 He was an experienced and capable horse rider3 and had also ridden in Japan for many years before coming to Australia.4
Takamasa was known to his friends and colleagues as ‘Taka’. They described him as calm, honest and loyal, a good friend with a good personality.5
Takamasa’s death was reported to the Coroner as it fell within the definition of a reportable death in the Coroners Act 2008 (the Act). Reportable deaths include deaths that are unexpected, unnatural or violent or result from accident or injury.
The role of a coroner is to independently investigate reportable deaths to establish, if possible, identity, medical cause of death, and surrounding circumstances. Surrounding circumstances are limited to events which are sufficiently proximate and causally related to the death. The purpose of a coronial investigation is to establish the facts, not to cast blame or determine criminal or civil liability.
Under the Act, coroners also have the important functions of helping to prevent deaths and promoting public health and safety and the administration of justice through the making of comments or recommendations in appropriate cases about any matter connected to the death under investigation.
Victoria Police assigned an officer to be the Coroner’s Investigator for the investigation of Takamasa’s death. The Coroner’s Investigator conducted inquiries on my behalf, including 1 Exhibit 37 to WorkSafe Hand-Up Brief of Evidence.

taking statements from witnesses – such as family, the forensic pathologist, treating clinicians and investigating officers – and submitted a coronial brief of evidence.
This finding draws on the totality of the coronial investigation into the death of Takamasa Takeda including evidence contained in the coronial brief. Whilst I have reviewed all the material, I will only refer to that which is directly relevant to my findings or necessary for narrative clarity. In the coronial jurisdiction, facts must be established on the balance of probabilities.6
In considering the issues associated with this finding, I have been mindful of Taka’s human rights to dignity and wellbeing, as espoused in the Charter of Human Rights and Responsibilities Act 2006, in particular sections 8, 9 and 10.
MATTERS IN RELATION TO WHICH A FINDING MUST, IF POSSIBLE, BE MADE Circumstances in which the death occurred
On the morning of 9 March 2020, Takamasa was with a group of four riders, taking horses to Thirteenth Beach in Barwon Heads for routine beach work under the supervision of Assistant Trainer Andrew Edwards. The riders arrived at the beach marker 40W carpark just after 6:30 am in a truck with four horses loaded. From the carpark, the group needed to cross Thirteenth Beach Road to get to the beach itself.7 The beach is designated as an area to work horses and is known locally as the ‘horse beach’.8
Thirteenth Beach Road, Barwon Heads, runs in an east-west direction, roughly parallel with the beach. It is a sealed carriageway with one lane for traffic in each direction. A solid centre white line with a short gap at the carpark divided the east and west bound traffic. A signposted speed limit of 80 km/h applied at the time of the collision.9 The road surface was flat, dry and in good condition.10 Dense shrubs grew alongside the road on both sides.11 Yellow 6 Subject to the principles enunciated in Briginshaw v Briginshaw (1938) 60 CLR 336. The effect of this and similar authorities is that coroners should not make adverse findings against, or comments about, individuals unless the evidence provides a comfortable level of satisfaction as to those matters taking into account the consequences of such findings or comments.

traffic signs depicting a horse being ridden and a woman and child pedestrian were present from both the east and west approaches to the carpark.12
At approximately 6:40 am, it was still somewhat dark. The evidence of witnesses varies on this point, with the riding group recalling that it was half-light13 or ‘maybe 50-50 light’,14 while other witnesses observed it to be ‘dark’,15 ‘very dark’16 or ‘almost pitch black’17. I accept that this divergent evidence was given in good faith and that subjective perceptions of darkness may vary depending on the perceiver’s relative adjustment to light conditions and the presence of other lighting, such as car headlights, which can cast surrounding areas into comparative darkness. There was no street lighting on this section of road.18 Mr Edwards stated that over the preceding month he had been gradually delaying the start of their beach visits to ensure that there was enough light to work safely with the horses on the beach. The riders were not wearing high-visibility or light-reflecting clothing, and were not using any lights, lamps or head torches. The horses had reflective strips approximately 5 cm wide and 30 cm long sewn diagonally across their saddle pads.19
The horses were unloaded from the truck and were calm and behaving well. All four horses were dark-coloured. Taka was assigned to ride a two-year-old, brown-coloured colt that had been to the beach on many occasions.
Mr Edwards stated that there was no set policy or procedure for crossing the road to the beach, but for safety he would always walk to the middle of the road and check the road in both directions, as he did on this morning. Mr Edwards could see approximately 800 metres towards the east, looking back towards Barwon Heads. He observed headlights of a vehicle about 500 metres away in that direction and called out to the riders that it was safe to cross.20
The riders and horses started to cross the road together. Of the four horses with riders, Takamasa was on the fourth horse, being the last to cross.
Mr Edwards was still standing in the middle of the road, observing the approaching vehicle, which did not appear to be slowing down. When the vehicle was approximately 100 metres 12 Statement of Jeremy O’Brien, Coronial Brief.

away, Mr Edwards started waving his arms and yelling at the car to slow down or stop. At this time, Mr Edwards was focused on getting the vehicle to stop and was not aware of the horses’ positions behind him. To avoid being struck by the vehicle, Mr Edwards moved to the southern side of the road, at which time he heard the screech of the tyres from the vehicle.
Mr Edwards turned and saw the vehicle hit the horse that Takamasa riding. The horse was hit on its left side and fell onto the car bonnet. Takamasa hit the windscreen of the vehicle and was thrown to the ground, landing on his left side. The horse got up immediately and moved towards the beach.21
A passing group of cyclists stopped to assist. One of the cyclists, Adrienne Currie, was qualified as a registered nurse and attended to Taka, observing that he appeared to have serious head injuries. On instruction from the 000 call-taker, Ms Currie performed CPR, assisted by Mr Edwards.22

COLLISION INVESTIGATION Scene investigations
Attending police examined the collision scene and took measurements, photographs and statements from witnesses.
The driver of the vehicle, Haylee Holt, remained at the scene and spoke with attending police.
Ms Holt produced a current driver’s licence24 and underwent a preliminary breath test for alcohol and preliminary oral fluid test for drugs, both of which returned negative results.
Ms Holt stated to police that she had been on her way to work, it was dark, and she had suddenly seen two or three horses being ridden across the road. She slowed and moved to drive around them, but there was another horse and she braked but hit it. She agreed that she didn’t see the horses until she was ‘basically on top of them’.25
24 It was subsequently confirmed that Ms Holt had no prior traffic offences recorded: Certificate under section 84(1) of the Road Safety Act 1986 (26 November 2020).
25 Statement of David Winton, Coronial Brief.
26 Statement of Michael Hardiman, Coronial Brief.
At the point of impact with the horse and Takamasa, the vehicle speed was approximately 36 km/h.
Criminal prosecution
A blood sample was taken from Ms Holt at 9:05 am at University Hospital Geelong28 pursuant to section 55BA(2) of the Road Safety Act 1986.29 Toxicological analysis of that sample identified the presence of delta-9-tetrahydrocamiabinol (THC)30 at a concentration of 3 ng/mL.
Ms Holt elected to provide no further comment to police in relation to the collision, as was her right. No other evidence is available to me in this investigation in relation to Ms Holt’s use of cannabis and the time at which she last ingested cannabis.
Forensic Physician Dr Jason Schreiber from the Victorian Institute of Forensic Medicine provided an expert opinion in relation to the level of THC detected in Ms Holt’s blood.31
Dr Schreiber explained that THC levels rise rapidly in the minutes following ingestion and peak within two hours, then fall rapidly and usually reach a baseline level in regular users at about 2-4 hours following administration. Blood THC concentrations of 2-5 ng/mL and recent cannabis smoking are suggested to be associated with substantial driving impairment, 27 Exhibit 1 to Coronial Brief – Traffic Incident System Incident Report, 15 March 2020.

30 The active component of cannabis.
31 Statement of Dr Jason Schreiber, Coronial Brief.
particularly in occasional smokers, however, it is also possible for a baseline level of 3 ng/mL to be found in regular users several days after last using cannabis.32
Dr Schreiber provided an opinion that: a) Ms Holt was driving after having consumed cannabis; b) she had a blood THC concentration of 3 ng/mL within three hours of the collision; c) the THC concentration may have been higher at the time of driving but could not be back-calculated; d) it is possible that the measured THC concentration was a baseline level from cannabis use several days before; e) in the absence of witnessed signs or symptoms of THC intoxication, it was possible that Ms Holt’s driving skills were affected by the low level of THC present, but this could not be conclusively determined.33
Ms Holt was charged and pleaded guilty to failing a drug blood test within three hours of the collision.34 At the Geelong Magistrate's Court on 20 April 2022, she was fined, her driver’s licence was cancelled and she was disqualified from driving for a period of six months.35
WORKSAFE INSPECTION AND INVESTIGATION Workplace inspection
WorkSafe inspectors attended the scene at approximately 8:45 am on the day of the collision, having been notified of the incident by Victoria Police.36
Inspector Glenn Woods observed that aside from the two yellow street signs, there was no other indication to approaching road traffic that horses may be crossing the road at the carpark location.37
Inspector Woods was informed by Danny O’Brien, owner and manager of O’Brien Thoroughbreds, that the company’s practices to ensure the safety of riders and horses when 32 Ibid.

crossing public roadways were not formalised in writing, and that employees were informed verbally of actions to be taken by the assistant trainer or by Danny O’Brien, if present.38
AR 122 Helmets […] (5) When mounted on a horse during darkness, every licensed person or registered person or permit holder must affix to his or her helmet a safety warning light of a type approved by Racing Australia, a PRA or the Stewards (except that this rule does not apply to any location where the Stewards have ruled that sufficient artificial lighting exists).40

41 Exhibit 5 to WorkSafe Brief of Evidence, Improvement Notice dated 9 March 2020.
Woods explained to Mr O’Brien that compliance with the improvement notice could be achieved by the company developing and implementing a formal safe system of work.42
As an interim measure, O’Brien Thoroughbreds was advised not to undertake any horse training activities involving movement on public roads and reserves until such time as a safe system of work had been implemented.43
O’Brien Thoroughbreds subsequently developed and implemented a formal safe system for road crossing with horses including the following: a) Horses and riders are to work from sunrise; b) All riders and supervisor must wear high visibility vest; c) All horses to be saddled with high visibility packing; d) Supervisor to inspect and assess horses and riders for compliance with above before mounting horses; e) Should a vehicle appear which may make crossing unsafe, get horses mid crossing to the other side and cease any other horses crossing. Recommence once safe.44
Training in the safe work system was provided to all relevant employees and O’Brien Thoroughbreds was deemed to be in compliance with the improvement notice.45 I note that, with the notable exception of the requirements for high visibility gear, the now formalised safe system of work largely reflects practices that were routine at the time of Takamasa’s passing.46 WorkSafe investigation and prosecution
On 10 March 2020, a WorkSafe investigation into the incident that caused Takamasa’s death was commenced by Inspector Jeremy O’Brien from the WorkSafe Enforcement Group and a brief of evidence was prepared.

46 Statement of Andrew Edwards, Coronial Brief; Trial transcript of DPP v O’Brien Thoroughbreds Pty Ltd (14 November 2023), T136.31-142.1.
On the basis of the evidence gathered, O’Brien Thoroughbreds was charged with one count of failing to provide and maintain for employees a working environment that is safe and without risks to health, contrary to section 21(1) of the Occupational Health and Safety Act 2004 (Vic).
On 30 November 2023, in the Magistrates’ Court at Geelong, a jury acquitted O’Brien Thoroughbreds of that charge.47
The standard of proof for coronial findings of fact is the civil standard of proof on the balance of probabilities, with the Briginshaw gloss or explications.48 Adverse findings or comments are not to be made with the benefit of hindsight but only on the basis of what was known or should reasonably have been known or done at the time, and only where the evidence supports a finding that they departed materially from the standards of their profession and, in so doing, caused or contributed to the death under investigation.
Pursuant to section 67(1) of the Coroners Act 2008 I make the following findings: a) the identity of the deceased was Takamasa Takeda, born 27 May 1988; b) the death occurred on 9 March 2020 at Thirteenth Beach Road & Blackrock Road, Barwon Heads, Victoria, 3227, from head injuries - horse rider struck by a motor vehicle; and c) the death occurred in the circumstances described above.
Having considered all of the circumstances, I make the following additional findings as to the circumstances of Takamasa’s death: a) The collision occurred as a result of low light conditions that impeded Ms Holt’s ability to see the horses and riders crossing the road in time to brake safely.
47 Letter from Victorian WorkCover Authority to Coroners Court of Victoria dated 19 December 2023.
48 Briginshaw v Briginshaw (1938) 60 CLR 336 at 362-363: ‘The seriousness of an allegation made, the inherent unlikelihood of an occurrence of a given description, or the gravity of the consequences flowing from a particular finding, are considerations which must affect the answer to the question whether the issues had been proved to the reasonable satisfaction of the tribunal. In such matters “reasonable satisfaction” should not be produced by inexact proofs, indefinite testimony, or indirect inferences…’.
b) Poor visibility of the horses and riders was compounded by the absence of highvisibility clothing, reflective gear or lights worn by the riders.
c) I am satisfied, on the balance of probabilities, that the level of THC detected in Ms Holt’s system impaired her driving ability on the morning of the collision to some extent. I am, however, unable to reach further particularised findings as to the degree to which this impairment contributed to the collision, particularly in circumstances where there were a number of other contributory factors.
d) Road surface conditions and weather conditions at the time of the collision did not contribute to the collision.
I am further satisfied that in the time since Takamasa’s passing, O’Brien Thoroughbreds has implemented a safe system of work to ensure the safety of horses and riders crossing public roadways, including requirements for riders to wear high visibility clothing and horses to be saddled with high visibility packing.
I note that in the time since Takamasa’s passing, the applicable speed limit at the collision site has also been reduced from 80 km/h to 60 km/h, which I consider appropriate.
In these circumstances, I consider the remediations that have taken place since Takamasa’s passing will, as far as is reasonably practicable, mitigate the risk of future similar incidents.
COMMENTS Pursuant to section 67(3) of the Act, I make the following comments connected with the death.
It is well established that THC intoxication can cause impairment in cognitive and psychomotor functions, producing risk taking behaviours that may impair driving skills. In drivers, THC intoxication is also associated with increased lane weaving, impaired criticaltracking tests, increased reaction times, and impaired divided-attention tasks. In frequent users of THC, complex tasks show impairment despite purported tolerance.49
What is less well known in the community is that the presence of THC in a person’s system, regardless of the regularity or recency of use, and regardless of the individual’s subjective 49 Statement of Dr Jason Schriber, Forensic Physician, Coronial Brief, citing Hartman RL, Huestis MA. Cannabis effects on driving skills. Clinical chemistry. 2013 Mar 1 ;59(3):478-92.
feeling of being impaired or intoxicated, can cause psychomotor effects that increase a driver’s risk of being involved in a collision.
A recent study into the role of impairing drugs in motor vehicle collisions examined data from the toxicological analysis of approximately 5,000 blood specimens collected over a five-year period pursuant to compulsory drug testing50 of drivers hospitalised as a result of a road traffic collision.51 Though the impact of cannabis use on crash risk has been the subject of debate, the study found that when THC was present in all driver categories (in the absence of any other potentially impairing substance), the odds of that driver being culpable52 for the collision was 1.9 times higher than for the control group of drug-free drivers. The increase in the likelihood of culpability for the collision was even more pronounced in drivers with higher blood THC concentrations: a) at THC concentrations in the range of 1 - 4.9 ng/mL, the odds of culpability was 1.6 times higher than the drug-free control group; b) at 5 ng/mL and above, the odds of culpability was 3.2 higher than the drug-free control group; and c) at 10 ng/mL and above, the odds of culpability was 10 times higher than the drug-free control group.53
These findings are particularly relevant to regular users of cannabis. As discussed above, the blood level of THC falls rapidly after ingestion and usually reaches a baseline level in regular users at about 2-4 hours after ingestion. In regular users, it is possible for a baseline level to be present several days after last using cannabis, when the user may no longer subjectively feel any effects of the drug. The rapid fall in THC level reflects its redistribution into the fatty tissues of the body, including the brain, where it exerts its psychomotor effects. This recent study affirms our understanding that the impairing effects of THC may continue throughout 50 Under the Road Safety Act 1986 (Vic).

52 Culpability analysis (sometimes referred to as responsibility analysis) was undertaken by examining the known circumstances of the collision using an 8-point assessment guide. This included scoring each collision for the condition of road, condition of vehicle, driving conditions, accident type, witness observations, road law obedience, difficulty of task, and level of fatigue. Each factor had a predetermined numerical score.
