The Investigation
Collision Occurs
Investigation commences
Information is gathered
The Institute of Traffic Accident Investigators
The Investigation
Mechanics of how an investigation is conducted is largely dependant upon SIO (collision investigator & vehicle examiner)
• Road Death Investigation Manual (2007) &
• ACPO Codes of Practice (2010 re-write)
(not mandatory)
The Institute of Traffic Accident Investigators
The Collision Investigator Role
Capture all available evidence
Identify extent of scene
The Institute of Traffic Accident Investigators
The Collision Investigator Role
• Interpret scene evidence
• Carry out any ‘testing’
• Examine Vehicles
• Driver related ‘issues’
The Institute of Traffic Accident Investigators
The Collision Investigator Role
• Review the evidence
• Compile comprehensive report

The Investigation
How can we be confident our collision investigator is applying the most
appropriate methods and research to support the investigation?
The Institute of Traffic Accident Investigators
Checking & Verification• Used established methods & principles• Been impartial • Conclusions well founded • overall approach thorough• Explored other avenues• No ambiguous statements / phrasing• Made available all the references they used • Stayed within their limits (small cog)• Are their approximations reasonable • Alerted other agencies• Audit trailed their work

Miscarriage of Justice
No accreditation scheme can prevent a thoroughly competent expert getting it
wrong on the day
The Institute of Traffic Accident Investigators
• Individual ‘registered’ (not mandatory)
• Peer review of case files
• 4 years of registration then revalidation
• CPD maintained & current cases

Codes of Practice and Conduct for Forensic Science Providers and Practitioners in the
Criminal Justice System
Applies to public, private practitioners whatever scope of science work prosecution or defence
“influence conduct”
The Institute of Traffic Accident Investigators
Legal requirements
• Duty to the Court
• Retain
• Record and
• Reveal

Good Practice
Central point for anyone to look-up the most up to date research and
practices
The Institute of Traffic Accident Investigators
Exhibits
‘The art and science of packaging’
• protect evidence• minimise handling• labelling for continuity• proper use of packaging

Pedestrian speeds
How long did it take the pedestrian to reach the collision point?
Research on Road Traffic 1965 or Eubanks 1998 or Tony Foster 2002 ?

Mobile PhonesEveryone thinks they know about phones!
• Who should examine it?• How is it best examined?• The first examination may be the
only opportunity to collect evidence
~~~~~~~~~~~~~~~~~~~~~
Competent to do so?
Methods are fit for purpose?
No change to data?
Record or audit all of processes?

Visibility of pedestrian / cyclists
Has the conspicuity of pedestrian and/or the cyclist been considered?
The Institute of Traffic Accident Investigators
Speed Assessments
Speed lost while skidding?
Critical speed cornering?
Equations of motion
Establish coefficient of friction between tyres and road surface
1. Skid tests
2. Range of values
