Conspicuous Lighting Studies

The annual number of motorcycle rider fatalities in the United States increased from 2294 in 1998 to 5290 in 2008 (National Highway Traffic Safety Administration, 2010). Many multi-vehicle motorcycle crashes involve right-of-way violations where another vehicle turns in front of, or crosses the path of an on-coming motorcycle. Improving the frontal conspicuity of motorcycles with auxiliary forward lighting may reduce these types of crashes. This book describes some recent studies sponsored by NHTSA on motorcycle conspicuity.
