6 SUMMARY OF CORONER’S CONCERN
During the course of the inquest evidence was given that  
1.  The speed limit for the stretch of road where the collision took
place is set at the National Speed Limit of 60 mph. 
2.  The speed limit approaching the series of bends where the  collision took place when travelling in a southerly direction is 40 
mph up until a point just before the series of bends at which point it increases to 60 mph 
3.  There is no road sign indicating a suggested maximum speed for
negotiating the series of bends. 
4.  A member of the public who arrived on the scene travelling south 
on B3390 described himself as an experienced motorcyclist who  had knowledge of this stretch of road. He stated “…(it is) a windy  country road that requires caution. There are multiple rises and  falls and short sections of road have restricted views. Visibility can be as little as 50-100 yards. Due to the road you have to ensure  your speed is under control as you don’t know what is coming  around the corner. I would say this lasts for approx. 2 kms until you enter the next village of Poxwell. I do not believe the road is a  60-mph road due to its layout.” 
5.  A Collision History Report for B3390 showed there had been 3  additional accidents in recent years on the 60 mph stretch of road
involving single vehicles. 
6.  There were no eye witnesses as to what caused Mr Thomas-Day to
lose control of his motorbike when negotiating the bend. The  weather was fine and dry and the incident occurred in daylight  hours.  
7.  There was no evidence to suggest Mr Thomas-Day was exceeding
the speed limit. 
7 ACTION SHOULD BE TAKEN 
In my opinion unless action is taken to address the above concerns then there is a significant risk of future deaths and I believe each of you have the power  to take such action. 
8 INVESTIGATION AND INQUEST 
On 26th of August 2025, I commenced an investigation into the death of Jet Cameron Thomas-Day, aged 22 years at the time of his death. 

The medical cause of death was  
1 (a) Fatal bleeding from traumatic injuries
How, when and where
On 23/8/25 Mr Thomas-Day was riding his motorbike northbound on the  B3390 in the direction of Crossways. Whilst negotiating a left-hand bend  Mr Thomas-Day’s motorbike  has gone on to its nearside  making contact with the road and causing loss of control of the motorbike which has 
then slid into the lane of the oncoming traffic. Mr Thomas-Day became  unseated and was found unresponsive close to the verge in the  northbound lane. Paramedics attended and pronounced him dead at the  scene. Dorset Police investigated and found no evidence of third-party  involvement. 

Conclusion
Road Traffic Collision
9 CIRCUMSTANCES OF DEATH
See 7 above
10 CORONER’S CONCERNS 
During the course of the inquest I heard evidence giving rise to concern. In my opinion there is a risk that future deaths could 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.  Has the correct speed limit been fixed for the stretch of road where the
collision has occurred 
2.  Is there sufficient signage to warn of the series of bends and should a 
suggested maximum speed for negotiating the bends be fixed.

I also may send a copy of the report to any other person who I believe may find it useful or of interest.

1. The Family 
2. The Chief Coroner
