INVESTIGATION and INQUEST 

On 18 March 2024 I commenced an investigation into the death of 63 year old 
Nigel William Sweet. The investigation concluded at the end of the inquest on 19 
December 2024.  

The medical cause of death was found as follows: 

1a Multiple Injuries 
1b Road Traffic Collision

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

Nigel William SWEET died on 7 March 2024 on the A38 between 
Trerulefoot and Tideford Cornwall from injuries sustained after he lost 
control of his motorcycle due to rider error whilst attempting to complete 
an overtake of another vehicle in wet conditions.  The motorcycle fell onto 
its side as Nigel lost control.  Nigel was separated from his motorcycle and 
he slid across the carriageway into the path of an oncoming vehicle which 
was unable to avoid him despite emergency braking and steering input.  
That oncoming vehicle drove over Nigel who suffered unsurvivable injuries 
as a consequence. 

The conclusion of the inquest was as follows: 

Road Traffic Collision 

4 

CIRCUMSTANCES OF THE DEATH 

The reason for the collision was found to be rider error by Nigel, in wet road 
conditions whilst attempting an overtake in a creeper lane. 

A creeper lane is an additional lane, added to a single carriageway for a short 
stretch to allow for overtaking.  There are a number on this stretch of the A38 
which present road users with brief opportunities to overtake slower moving 
vehicles, before the road reverts to single carriageway on both sides. 

Nigel had overtaken at least one vehicle and was attempting to overtake a second 
vehicle by using the additional lane of the creeper lane. There was steady and 
oncoming traffic on the other carriageway.  Nigel had insufficient space in the 
creeper lane to safely complete the overtaking manoeuvre of the second vehicle. 
Nigel lost control of his motorcycle whilst under braking at which time he was 
likely trying to get back into the single carriageway at the end of the creeper lane.  
In that sense the creeper lane contributed to the collision.  

The court found that there was nothing that the driver of the oncoming vehicle 
could have done to avoid Nigel.

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.  –

 Information Classification: PUBLIC 

(1)  The court found that this stretch of the A38 from Carkeel roundabout to 

Trerulefoot roundabout has a history of a higher proportion of road traffic 
collisions compared to equivalent roads.  This is because of the nature of 
the A38 over this stretch which features predominantly single carriageway 
layout with occasional creeper lanes. 

(2)  The court heard evidence that a safety scheme had been developed to 
introduce average speed cameras for this stretch of the A38 but that 
funding had not yet been approved.  The safety scheme was specifically 
designed to reduce the higher proportion of collisions on this stretch of 
road.

ACTION SHOULD BE TAKEN 

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

7 

YOUR RESPONSE 

You are under a duty to respond to this report within 56 days of the date of this 
report, namely by 17 February 2025. I, the coroner, may extend the period.

2  CORONER’S MATTERS OF CONCERN 

The MATTERS OF CONCERN are as follows: –  

a.  The court found that this stretch of the A38 from Carkeel roundabout to 
Trerulefoot roundabout has a history of a higher proportion of road traffic 
collisions compared to equivalent roads. This is because of the nature of 
this  stretch  which  features  predominantly  single 
the  A38  over 
carriageway layout with occasional creeper lanes.   

b.  The  court  heard  evidence  that  a  safety  scheme  had  been  developed  to 
introduce  average  speed  cameras  for  this  stretch  of  the  A38  but  that 
funding  had  not  yet  been  approved.  The  safety  scheme  was  specifically 
designed  to  reduce  the  higher  proportion  of  collisions  on  this  stretch  of 
road. 

DETAILS OF ACTION TAKEN 

3 

a.  Nature of the A38 All Purpose Trunk Road 

The A38 Trunk Road between Carkeel Roundabout and Trerulefoot Roundabout 
is  a  single  carriageway  road  approximately  6.0  miles  (9.6km)  in  length  and 
traverses  through  rural  and  urban  areas.  Carkeel  Roundabout  is  situated  to  the 
east in Saltash and Trerulefoot to the west. 

The  geometry  of  the  route  is  constrained  by  topography,  development,  water 
courses, structures and open countryside.   

The  route  is  subject  to  a  50mph  speed  limit  which  reduces  to  40mph  in  the 
villages of Landrake and Tideford. 

The  matter  of  concern  raised  refers  to  ‘creeper  lanes’,  which  is  known  in 
highways terms as a wide single (carriageway)  2 + 1 road layout. This means 1 
direction  of  travel  allows  for  2  lanes  of  traffic  and  the  other  direction  of  travel 
allows for 1 lane of traffic. This road layout is detailed in the Design Manual for 

1

 
 
 
 
 
 
 
 
 Roads  and  Bridges  (DMRB),  Standard  CD109  Highway  link  design.  The 
Standard  can  be  found  on  the  following  link1  and  the  layout  described  under 
section 6 pages 26-37. 

Wide  single  2  +  1  road  layouts  provide  an  opportunity  for  vehicles  to  safely 
overtake  slower  moving  vehicles  on  single  carriageways  (e.g.  heavy  goods 
vehicles are restricted to 40 mph on single carriageway roads). 

The  layout  is  also  used  where  uphill  gradients  exceed  2%  and  are  over  500 
metres  long.  In  this  situation  the  layout  provides  a  climbing  lane  for  slower 
vehicles and an opportunity for other road users to safely overtake them.  

As wide single 2 + 1 road layouts help prevent congestion, which could result in 
road users performing injudicious overtakes in undesirable locations, we have no 
plans to remove this layout from the DMRB Standards or at this location. 

Road traffic collision review 

National  Highways  is  the  Highway  Authority  for  the  Strategic  Road  Network 
(SRN)  of  major  A-roads  and  most  motorways  in  England  including  the  A38  at 
the location of this collision. 

The safety performance of all roads  that National Highways is responsible for is 
continually  monitored  using  STATS19  data  (the  Department  for  Transport’s 
validated collision data). 

The  most  recent  5-year  validated  data  (between  2019  and  2023)  shows  that  60 
collisions (97 casualties) have been recorded for the 6 mile (9.6km) section of the 
A38  between  Carkeel  and  Trerulefoot  roundabouts.  This  is  summarised  as 
follows: 

•  2 Fatal collisions (2 casualties) 
•  13 Serious collisions (17 casualties) 
•  45 Slight collisions (78 casualties)  

Road traffic collision comparison 

The  same  validated  collision  data  as  published  by  the  DfT  annually,  is  used  to 
compare the safety performance of all roads we are responsible for in England. 

The A38 between Carkeel and Trerulefoot roundabouts  has a 51% higher injury 
collision rate than the  national average for our similar single carriageway roads 
in the South West.  This section of the A38 road is 35th lowest performing route 
in the South West out of 39 routes, in terms of its collision rate performance.

4d1b4bd6c9fa?inline=true 

2 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 For  fatal  and  serious  injuries,  this  section  of  the  A38  has  a  20%  Killed  and 
Seriously Injured (KSI) rate which is 8% higher than the national average for our 
similar  single  carriageway  roads.  However,  the  Road  Accidents  Great  Britain 
database2 for 50mph single carriageway roads during the same data period shows 
that the KSI rate for the whole of Great Britain  is 23%.  This is higher than the 
20% of this section of the A38. Therefore, whilst the KSI-to-total casualties ratio 
on the A38 in Cornwall is higher than our NH average, it is better than GB wide. 

Although this data demonstrates there are other  similar roads with greater need, 
we completed a pipeline study ‘A38 Carkeel to Trerulefoot’ in 2022.  The study 
considered  many  options  for  interventions  ranging  from  providing  a  dual 
carriageway  around  the  villages,  widening  of  the  A38,  to  small  targeted 
interventions.    The  outcome  of  this  study  found  that  the  extensive  engineering 
required  to  dual  or  widen  the  A38  within  the  existing  topography  was 
unaffordable  at  the  time  and  a  proposal  largely  focused  on  several  online 
interventions was selected. Following the Secretary of State’s Written Ministerial 
Statement published on 9 March 2023 that the pipeline schemes, which included 
the  A38  Carkeel  to  Trerulefoot  scheme,  previously  earmarked  for  RIS3  (2025-
30)  would  continue  to  be  developed  and  considered  for  inclusion  within  RIS4 
(2030-35). 

b.  Safety scheme to introduce average speed cameras 

Following  deferral  of  any  major  improvement  scheme,  as  a  member  of  the 
external  South  West  Vision  Zero  Road  Safety  Partnership,  National  Highways 
has  been  working  closely  with  Cornwall  Council,  Devon  and  Cornwall  Police 
and other external partners to identify interventions that could reduce the number 
of  collisions  on  this  section  of  the  A38  and  improve  the  safety  of  residents  in 
Landrake and Tideford. 

Our  current  plan  is  to  implement  an  Average  Speed  Camera  Systems  (ASCS) 
between  Carkeel  and  Trerulefoot  and  to  reduce  the  speed  limit  through  the 
villages of Landrake and Tideford to 30 mph. We aim to publish the notice for 
the Traffic Regulation Order (TRO) in March 2025 and begin implementation of 
the ASCS and signs in May of financial year 2025/2026. 

ASCSs  have  already  been  successfully  used  on  our  Strategic  Road  Network  to 
reduce  collision  rates.  This  includes  on  the  A38  in  the  Glyn  Valley,  where 
collision rates have reduced.  It is anticipated that the ASCS planned for the A38 
between Landrake and Tideford will increase speed limit compliance and driver 
concentration, both of which are known to reduce collision rates.   

I  can  confirm  that  since  the  inquest  on  19th  December  2024,  the  business  case 
and  funding  for  the  ASCS  has  been  agreed,  but  not  yet  secured,  and  work  is

 scheduled to commence in Q1 2025/26. 

Once installed, the road safety performance of the whole length of the A38 will 
continue to be monitored and if necessary, further improvements considered.

SAFETY OF ROAD USERS 

The safety of our road users is an imperative for our business and safety is a core 
value of our organisation. We are working hard to make our entire network safer.  
We consider that the  action we have  both taken to date, and plan to take, could 
help to prevent future deaths on the A38 at this location. 

All  improvements  to  the  network  require  to  be  progressed  in  a  considered  and 
controlled fashion  so  that  the  consequences  of  changes  to  the  network  are  fully 
understood  and  any  linked  safety  risks  are  eliminated  or  reduced  as  far  as 
possible. 

Furthermore,  works  to  the  Strategic  Road  Network  are  required  to  demonstrate 
value  for  money,  in  accordance  with  the  Highways  England:  Licence  (April 
2015), and our duty to manage public funds.
