2-1 Accidents by primary/secondary party*3 and casualties by age group
Figure 2 shows the number of crossing collisions between mopeds (as Party 1 or 2) and various types of vehicles, the most fatal type of accident. The figure is outstanding for collisions between mopeds as Party 2 and standard/mini passenger cars as Party 1, followed by collisions between mopeds as Party 1 and standard/mini passenger cars as Party 2.
The number for the former case is approximately 3.7 times higher than that for the latter, 16,252 and 4,397, respectively.
Figure 3 illustrates the number of casualties by age group for mopeds, both as primary and secondary parties.
Young people (16-24 years old) constitute the age group most frequently killed or injured regardless of whether they are Party 1 or 2; they account for 6,861 or about 23% of all casualties, especially when they are Party 2.
*3: "Primary party" is the more negligent of the drivers of the vehicles, etc. first involved in a traffic accident, or, if the level of negligence is almost the same, the less injured of the two (referred to as "Party 1").
: "Secondary party" is the driver of the vehicle, etc. other than the primary party first involved in a traffic accident (referred to as "Party 2").
