Problem interstate commercial drivers are not being effectively detected and controlled by Federal and State regulations and driver licensing systems. This paper highlights findings in the National Transportation Safety Board's 'Safety Effectiveness Evaluation of Detection and Control of Unsafe Interstate Commercial Drivers Through the National Driver Register, State Driver Licensing Policies, and the Federal Motor Carrier Safety Regulations." It points out that even though motor carriers are required to do certain driver investigations, there is no single source they can utilize to obtain a nationwide accounting of driver records.

Safety Board-recommended changes to the National Driver Register, Federal Motor Carrier Safety Regulations, as well as State adherence to the one-license concept are explained.

Selected accident investigations are used to provide real world examples of the problem.
