A Short Primer on Scientific Method
According to the scientific method, a theory must fulfill three criteria. First, its claims must be testable; second, its explanations must be difficult to vary; and finally, its test results must be truthfully reported.

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.

NMI Graduated Driver License (GDL) System

The National Motorcycle Institute (NMI) Training/Licensing System reduces motorcycle driver Fatalities. This is a basic Graduated Drivers License type of system, intended to be administered by civil servants. It is based on the permit-then-endorsement system previously used in the USA that separated training from endorsement testing. This two-step system is still used by most states for passenger vehicle driver licensing. The two-step Motorcycle Learner-Permit-Then-Endorsement System was well established, prior to the motorcycle industry’s Beginner-Training-License Waiver system that is now in use in many states. The NMI system emphasizes an “Opt-Out” feature to allow new motorcyclists a guilt-free way to discontinue training. Here is the detailed explanation of the flowchart: 6.

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!

Warning Sign, Participating in Motorcycling may lead to serious injury or death.  Enjoy Responsibly

To summarize the facts:
1. 38 times per person-mile more dangerous.
(27 times per vehicle-mile since cars carry more passengers.)
2. The motorcycle is almost always the striking vehicle.
3. The motorcycle driver (rider-operator) typically has a Motorcycle endorsement.


We do not promote or discourage using motorcycles, we promote making informed choices.
