Bicyclists represent 12% of all on-road injuries in Missouri

NOTE: This article has been superceded by a more recent summary of this same data.


Looking at the Missouri Highway Patrol's figures for bicycle injuries, the number is quite low--for the years 2000-2002, bicycle crashes represented between 1.3% and 1.5% of all traffic injuries measured by the Highway Patrol.

However, the Highway Patrol's figures only measure collisions in which a motor vehicle actually collides with a bicycle.

This excludes a broad range of bicycle-related injuries that happen on the road, such as:

  • Bicylist hits a parallel bar grate, a curb, roadway imperfections, etc., and falls
  • Motorist intentionally or unintentionally runs bicyclist off the road, however never physically contacts bicyclist
  • Bicyclist must take evasive action due to motorist, avoids colliding with motorist but still crashes
  • Simple falls, bicycle-bicycle collisions, bicycle-pedestrian collisions, bicycle-dog collisions, bicycle-road debris collisions, etc.

Here is a summary of bicycle and pedestrian injuries which includes bicycle-automobile injuries but also all other types of bicycle and pedestrian injuries on the public roads:

Missouri DHSS InjuryMICA figures, 1996-2002

                         Number   Percentage
                         -------  ----------
   TOTAL INJURIES[1]     :  670,763  100.0%   
Bicycle injuries[2]   :   78,724   11.7%
Pedestrian injuries[3]:   23,144    3.5%

In short, when ALL on-road bicycle injuries are considered, bicycle injuries comprise nearly 12% of all roadway injuries.

Dr. Greg Luttrell is currently working to research in this area of bicycle injuries. Luttrell has found that, nationwide, about 10% of bicycle crashes are with a motor vehicle and the other 90% are "bike only". (In Missouri it is more like 94%/6% according to the InjuryMICA data 1996-2002.)

Luttrell also says that "the average out of pocket cost of a bike only crash (not involving a motor vehicle) was over $3,200. Taken nationwide, this results in almost $1.5 billion in annual bike crash costs (again, not including insurance payments)."

[1]. Total injuries was calculated by adding the TOTAL from the "Traffic injury statistics" together with the total bicycle non-motor vehicle injuries and the total pedestrian non-motor vehicle injuries from "Bicycle/Ped non-motor vehicle injury statistics". The purpose of this was to include all on-road injuries, whether involving a motor vehicle or not, but to exclude off-road injuries not involving a motor vehicle.
