COLLISION DIAGRAM
A basic diagram or unknown value is required for all
accidents, and is especially important for fatality
accidents. Indicate “Unknown” only if not enough
information is known to reconstruct a basic scene.
Draw a concise diagram of the roads and vehicles
showing their names, and the movement(s) of vehicle(s).
This does not have to be a scaled drawing and
should be completed whether vehicles were moved
from the scene or not.
Arrows showing vehicle movements leading to the collision are sufficient. Examples: " “
indicates a head-on collision or " • " shows a vehicle striking a pole (or another fixed object).
Show location features like a creek or river, RR tracks etc. if possible.
Other suggested inclusions:
Direction of units prior to and after impact, skid marks, etc.
Location of signs, traffic controls, and reference points
Location of other property hit or damaged (trees, signs, etc.)
Location of temporary roadway conditions (construction or maintenance zone, etc.)
Measurements to locate the accident relative to specific, fixed, and identifiable points
Note that there is a symbol located to the top right of the collision diagram. Please
indicate the North (N) direction using this symbol. Note: Electronic diagrams may use a different
north arrow orientation.
SPECIAL EVENT…can be used for tracking accidents at or related to an unusual or unique
community event.
Examples: “Kansas State Fair” (RN Co.), “Kansas Speedway Races” (WY Co.), “Walnut Valley
Music Festival” (CL Co.), “Verizon Theater Concert” (WY Co.), etc.
Note: To do research on this data field, consistency is very important in listing the event you would
like to show in this box. If several accidents for instance, happen in conjunction with the Kansas
State Fair, the law enforcement officers in Reno County should make sure they all list the “Special
Event” in the same way. “Kansas State Fair” versus “KS State Fair” or whichever way is agreed
upon. The main point here is to be consistent in the way the “Special Event” is spelled/listed so it
can be researched later.
SPECIAL DATA This box is for recording additional description of an accident location such as for
a parking lot (Dillons, Walmart, etc) or a rest area description (Matfield Green, East Topeka,
Lawrence, etc), or for any additional coding useful to accident reporting.
