Research Studies & Reports

DMV’s Research & Development Branch has been conducting research and producing studies and reports since the 1950s. Research & Development reports help DMV to measure the impact of new laws on making drivers safer. We also identify areas where we can improve our processes, explore new approaches to solving existing problems, and branch out into new opportunities to serve you better.

Comparison of Accident and Conviction Rates for Commercial Drivers Tested Under the Employer Testing Program and Commercial Drivers Tested by DMV

By: Eric Chapman

The Employer Testing Program (ETP) allows eligible employers to conduct drive tests and issue the Certificate of Driving Skills (DL 170) to commercial vehicle operators they employ. To participate in the program, an employer must demonstrate that their driving test and examiners meet standards set by DMV. Employers in the program are subject to annual inspections and audits by the department’s Intrastate Audits Unit. If any deficiencies on the part of the employer are found, the department may impose restrictions ranging from warning letters to revocation or cancellation of the employer’s testing authorization. Approximately 980 employers participate in this program, 60% of which are in the government sector (e.g., fire departments and Caltrans). To help in monitoring the program, the department’s Research and Development Branch compared the driving records of licensed commercial drivers tested under the ETP to commercial drivers tested by DMV. The remainder of this paper presents the methods and results of the driver record analyses and a discussion of the findings.
