INVESTIGATION and INQUEST 

On Monday 18th March 2019 I commenced an investigation into the death of Ryan 
Gareth TAYLOR. The investigation concluded at the end of the inquest on 6th May 2021. 
The conclusion of the inquest was as follows 

 Medical cause of death  

1(a):  Multiple Injuries. 
1(b):  Road Traffic Collision 

The four questions - who, when, where and how – were answered as follows … 

Ryan Gareth TAYLOR died on 16th March 2019 at A390, Coliza Hill, St Austell, 
Cornwall from trauma sustained in a road traffic collision after he lost control of his 
vehicle due to aquaplaning in heavy rain. 

Conclusion 

Road Traffic Collision 

4 

CIRCUMSTANCES OF THE DEATH 

Ryan died when his Jaguar XF suddenly veered across the road and collided with 
another vehicle, a Mazda MX5, which was travelling in the other direction.  Ryan was 
pronounced dead at the scene by attending Paramedics.  The driver of the Mazda, 

, sustained life changing injuries. 

The collision occurred during the hours of daylight. Visibility was poor due to heavy rain 
and poor light conditions. The road surface was very wet. The sky was overcast with 
heavy cloud.  

The court heard the following evidence in connection with road drainage at the scene. 

Coliza Hill Slip Road 
There are gullies on the south-eastern side of the slip road. These were clear of debris 
at the time of inspection, but due to the steep hill, under conditions of exceptional 
rainfall, it is possible that a fast flow of water may overwhelm the existing gully grid 
capacity. A change of camber takes water falling on the lower end of the slip road onto

the main carriageway, although this is always likely to be the minor flow. A 
recommendation has been made by Cormac to enhance the size of or provide additional 
gully grids for better capture of water above the changeover point, and to minimise 
surcharge at the lower end of the slip road. 

A390 Coliza Hill (eastbound description) 
The A390 drains to the north-western side of the road in accordance with standard super 
elevation of the carriageway for the left-hand bend, until a short distance above the 
entrance to the layby, when the changeover occurs and water begins to drain along the 
road and then to the south  eastern side. Gullies intended to capture this water before 
the changeover point were fleeced over with debris from adjacent trees at the time of 
site visit. It is not known if this was the case at the time of the collision. Drainage 
standards have altered since the design and construction of the original A390 
improvement, since adopting higher inundation calculations due to anticipated climate 
change and other factors. Cormac & Cornwall Council are investigating the capacity of 
the underlying drainage system and outfalls with a view to increasing both the size and 
number of gullies to improve capture and system resilience. 

The Inquest findings of fact were as follows 

•  There was no evidence of excessive speed or unsafe driving by Ryan at the 

time of the collision or in the period leading up to the collision. Indeed, there was 
evidence from other road users that Ryan was driving appropriately for the 
conditions. 

•  There was meteorological evidence a large band of heavy rain passing over the 
location of the collision and that just prior to the collision rainfall of 20 - 30 mm 
was recorded. Eyewitnesses referred to the driving conditions as being poor due 
to the heavy rain and excessive water.   

•  Examination of road drainage at this location revealed that during periods of 

heavy rainfall surface water from the adjoining road known as Coliza Hill is likely 
to converge with surface water on the A390 in the vicinity of where the Jaguar 
initially lost control. 

•  Ryan was driving a rear wheel drive car. The evidence of the forensic collision 
investigator was that a rear wheel drive car is more likely to aquaplane in these 
circumstances than a front wheel drive car.   

•  The manner in which Ryan’s car crossed the carriageway was found to be 

consistent with a rear wheel drive car aquaplaning in wet conditions. The 
forensic collision investigator’s evidence was that Ryan would have had little or 
no warning of this sudden loss of control. 

From these findings of fact driver error was ruled out.  The cause of the collision was 
found to be the surface water from Coliza Hill converging with surface water on the A390 
following heavy rain just prior to the collision.  The inquest found that Ryan lost control of 
his car as he was traversing the converging surface water which had inundated the road 
at this point. This caused the rear tyres of his vehicle to lose traction with the road 
surface, either causing it to rotate and suffer a sudden and catastrophic loss of control 
such as that witnessed by other road users, or causing Ryan to over steer in an attempt 
to regain control, which would have resulted in the same consequences.

CORONER’S CONCERNS 

During the course of the inquest the evidence revealed matters giving rise to concern. In 
my opinion there is a risk that future deaths will occur unless action is taken. In the 
circumstances it is my statutory duty to report to you. 

The MATTERS OF CONCERN are as follows.  –  

(1)  During periods of heavy rainfall surface water from the adjoining road known as 
Coliza Hill is likely to converge with surface water on the A390 in the vicinity of 
where Ryan initially lost control of his car. 

(2)  A rear wheel drive car had been involved in an aquaplaning incident at the same 

location in similar conditions, four years before this collision. 

(3)  Improvements to road drainage are feasible in this particular location but have 
not yet been implemented. These improvements may diminish the risks of 
vehicles aquaplaning due to converging surface water. 

6 

ACTION SHOULD BE TAKEN 

In my opinion action should be taken to prevent future deaths and I believe you and your 
organisation have the power to take such action.

YOUR RESPONSE 

You are under a duty to respond to this report within 56 days of the date of this report, 
namely by 21st July 2021. I, the coroner, may extend the period. 

Your response must contain details of action taken or proposed to be taken, setting out 
the timetable for action. Otherwise you must explain why no action is proposed.

Dear Mr Davies 

Regulation 28 Report – Ryan Gareth Taylor (Deceased) 

Thank you for your letter of 25th May 2021 and the accompanying Regulation 28 Report, in connection 
with the recent inquest into the death of Mr Ryan Taylor at A390 Coliza Hill, St Austell.  

I have discussed the findings of the inquest and your subsequent recommendations with senior 
officers of Cornwall Council, the highway authority for the A390. I am pleased to confirm the following 
actions, in addition to those already undertaken and outlined at the inquest.  

•  Signs will shortly be erected on both approaches warning of the possibility of surface water on the 

road ahead. This is an interim measure pending more substantial improvement. 

•  The existing gully grids on the Coliza Hill slip road will be replaced with larger capacity gratings. 
This is scheduled to take place in October, in combination with maintenance work programmed 
after the summer road works embargo period.  

•  Detailed drainage and topographical surveys will be undertaken on the main road alignment, 

again in combination with the scheduled maintenance work in October.  

Once the detailed survey information has been obtained it will be possible to identify if and how the 
main road drainage system can be upgraded, and a scheme potentially designed and implemented 
accordingly. You will appreciate that it is not possible to give a precise idea of what this further work 
will entail and how long it will take at the present time. You may be assured though that the highway 
authority is viewing this as a priority site. I will confirm to you the results of this investigatory work 
and any proposals arising from it when they are known.
