Photographing site locations
Although the police will often produce photographs and scale plans of the site of an accident, it is usually essential for the investigator to examine, survey and photograph the site of an accident before a proper report can be prepared.
It is all too easy to gain a false impression of a site without actually seeing it.
Plans and photographs prepared by other persons may not be sufficiently detailed or may not show some feature that the investigator believes may be important to his analysis. Additionally, that feature may not become apparent until the site is personally inspected.
Photographs showing the view that each party would have had during the few seconds prior to the accident can be particularly useful.
Any marks or debris still present at the site can be photographed.
