The National Highway Traffic Safety Administration (NHTSA), a division of the United States Department of Transportation, has this brief and informative cycling overview on their Bicyclists Road Safety website page (HERE). Good info for trike pilots to know:
As you might expect, when a crash occurs between motor vehicle and a bike, it is the cyclist who is most likely to be injured. Bicyclists accounted for 2 percent of all traffic deaths and 2 percent of all crash-related injuries in 2014. Bicyclist deaths occurred most often between 6 p.m. and 9 p.m. (20%) and in urban areas (71%). The vast majority of bicyclists killed were male (88%) and the largest number of males injured were between 20 to 24 years old. About one in five bicyclists (21%) killed in crashes had blood alcohol concentrations (BACs) of .08 grams per deciliter (g/dL) or higher, the illegal alcohol level in all States. A large percentage of crashes can be avoided if motorists and cyclists follow the rules of the road and watch out for each other.
