14. Conspicuity of the motorcycle is a critical factor
in the multiple vehicle accidents, and accident involvement is significantly
reduced by the use of motorcycle headlamps (on in daylight) and the wearing of
high visibility yellow, orange or bright red jackets.
15. Fuel system leaks and spills were present in 62% of
the motorcycle accidents in the post-crash phase. This represents an undue
hazard for fire. 16. The median pre-crash speed was
29.8 mph, and the median crash speed was 21.5 mph, and the one-in-a-thousand
crash speed is approximately 86 mph.
17. The typical
motorcycle pre-crash lines-of-sight to the traffic hazard portray no
contribution of the limits of peripheral vision; more than three-fourths of all
accident hazards are within 45deg of either side of straight ahead.
18. Conspicuity of the motorcycle is most critical for
the frontal surfaces of the motorcycle and rider.
19.
Vehicle defects related to accident causation are rare and likely to be due to
deficient or defective maintenance.
20. Motorcycle
riders between the ages of 16 and 24 are significantly overrepresented in
accidents; motorcycle riders between the ages of 30 and 50 are significantly
underrepresented. Although the majority of the accident-involved motorcycle
riders are male (96%), the female motorcycles riders are significantly
overrepresented in the accident data.
22. Craftsmen,
laborers, and students comprise most of the accident-involved motorcycle riders.
Professionals, sales workers, and craftsmen are underrepresented and laborers,
students and unemployed are overrepresented in the accidents.
23. Motorcycle riders with previous recent traffic
citations and accidents are overrepresented in the accident data.
24. The motorcycle riders involved in accidents are
essentially without training; 92% were self-taught or learned from family or
friends. Motorcycle rider training experience reduces accident involvement and
is related to reduced injuries in the event of accidents.
25. More than half of the accident-involved motorcycle
riders had less than 5 months experience on the accident motorcycle, although
the total street riding experience was almost 3 years. Motorcycle riders with
dirt bike experience are significantly underrepresented in the accident data.
26. Lack of attention to the driving task is a common
factor for the motorcyclist in an accident.
27. Almost
half of the fatal accidents show alcohol involvement.
28. Motorcycle riders in these accidents showed
significant collision avoidance problems. Most riders would overbrake and skid
the rear wheel, and underbrake the front wheel greatly reducing collision
avoidance deceleration. The ability to countersteer and swerve was essentially
absent.
29. The typical motorcycle accident allows the
motorcyclist just less than 2 seconds to complete all collision avoidance
action.
