We use science to understand and manage the danger of motorcycling.

Although motorcycle drivers and passengers (Motorcyclists) are fatally injured 27 times more often per vehicle than car drivers and passengers (Motorists), this fact understates the danger of riding upon motorcycles. This understatement happens because the occupancy per vehicle of cars is so much higher than motorcycles. Cars carry many more, and more frequently carry, passengers. The occupancy of cars is about 1.5 times that of motorcycles. This means that riding on a motorcycle is about 38 times more dangerous than riding in a car, per person! (38 times is the USA 5-year average.)

Motorcycle Driver Crash Image

The one fact you must know before you decide to operate a motorcycle on public roadways: In fatal motorcycle crashes, the motorcycle is almost always the striking vehicle. In 40% of the crashes the motorcycle was the ONLY vehicle. You should also become aware of Inattentional Blindness before you choose to ride on motorcycles in traffic.

Motorcycle License Endorsed/Not-Endorsed Tombstone Image

About 86% of all motorcycle drivers killed had a motorcycle endorsement (73% Valid+Endorsed and 13% not valid but endorsed). Only 14% did not have an endorsed license (27% not valid minus 13% not valid but endorsed). This is the result when you include all motorcycle drivers killed with a motorcycle endorsed license, whether or not the license is Suspended, Expired, Revoked, Foreign, or Valid. Please learn the difference between the terms “Endorsed” and “Valid.” For example, in 2015, 13% of the Motorcycle Driver fatalities had an Endorsed License that was Suspended, Revoked, or Foreign whereas 14% of the Motorcycle Driver fatalities did not have an endorsement. When the suspended/revoked endorsements are added to the non-endorsed fatalities, the result is 27% “Not Valid,” as published by NHTSA. It is important to remember about one half the “Not Valid License” count included those who had possessed a motorcycle endorsement.

There are over 150 Other Vehicles using the road for every single motorcycle!


When scientifically evaluating any aspect of motorcycles and public roadways, it is important to recognize that there are very few motorcycles compared to the number of other vehicles. For example, annually, there are more than 150 other vehicles on the road for every single motorcycle!
