Motorcyclists' speed and "looked-but-failed-to-see" accidents.

Previous research on motorcycle crashes has shown the frequency and severity of accidents in which a non-priority road user failed to give way to an approaching motorcyclist without seeing him/her, even though the road user had looked in the approaching motorcycle's direction and the motorcycle was visible. These accidents are usually called "looked-but-failed-to-see" (LBFS) accidents. This article deals with the effects that the motorcyclist's speed has in these accidents.
