Take traffic collision photographs as soon as possible, before the scene
can change. Show the relationship between objects in the scene. It may
be a good idea to show camera locations on the field sketch.
Photographs at the Accident Scene
- Show where the
vehicles came to rest and in what position. Show the relationship of
each vehicle with each other. Include some permanent, recognizable landmark
in the photograph.
- Photograph debris
or marks on the roadway (such as tire marks and gouges)
- Photograph skid
marks. Take one photograph the direction of the mark to show the direction
the vehicle was traveling. Take another photograph from the side to
show the length of the skid mark. Photograph for the greatest depth
of field possible. Photograph the contact patch on the tire and the
top of the skid mark to show tire tread type. Use a polarizing filter
to cut any reflection on the roadway surface.
- Show the view
each driver had approaching the key point of the accident. Show any
view obstructions. Photograph from inside the vehicle. A 35mm lens will
provide a good representation of a person’s view.
- Photograph the
view from the point a witness observed the accident, at witness’ eye
level. A 35mm lens will provide a good representation of a person’s
view.
- Photograph evidence
to identify hit and run vehicles. Photograph paint transfer, height
of damage, pieces of suspect vehicle left at scene, tire impressions,
and blood.
- Photograph the
interior of any vehicle in an injury or fatal accident. Show anything
in the interior that indicates body contact. Use an electronic flash
when photographing the interior of a vehicle.
Night Photography
Use multiple flash, painting with light, or available light for large
scenes, extra long skid marks, or to show two vehicles some distance apart.
Technical Photographs of Damage to a Vehicle
- Vehicle damage
is photographed to help reconstruct the accident. Reconstruction can
determine how one vehicle fitted against another vehicle or fixed object,
from what direction the major force came, whether the vehicle rolled
over, or whether it had more than one collision during the accident.
- Take vehicle damage
photographs at the scene before the vehicles are moved so they will
show no additional damage due to removal operations.
- Take six photographs.
Two from each side in line with the axles. Take one of each end of the
vehicle, straight on. If possible, take one more from overhead. (Do
not take any oblique or corner photographs to show damage because the
photograph will not be aligned with the axis of the vehicle. Oblique
photographs conceal the amount and direction of the damage.
- Use scales to
indicate height and size of damage in the photographs.
- Always use electronic
flash to fill in shadows within the damage.

Do not take oblique
or corner photographs to show vehicle damage.
Oblique photographs conceal the amount and direction of the damage. Compare
the appearance of the damage in the photograph above with the two photographs
below.
