About This Website

The University of Cincinnati, in association with eScience & Technology Solutions, Inc. (eSTS), University of California, Los Angeles (UCLA), and North Dakota State University’s (NDSU) Upper Great Plains Transportation Institute (UGPTI) developed the reference documents presented on this website through an FMCSA-sponsored Commercial Driver’s License Program Implementation (CDLPI) Grant Agreement (Number 69A3602040473CDL0OH) for the “National Commercial Driver License Program Assessment” project. The goal of the project is to identify opportunities to strengthen the National CDL Program and enhance the ability of State Driver Licensing Agencies (SDLAs) to maintain compliance with Federal Motor Carrier Safety Regulations (FMCSRs) 49 CFR 383 and 384.

The Traffic Citation Lifecycle

The Traffic Citation Lifecycle Process Flow diagram illustrates when each stakeholder group is involved. The lifecycle begins when a law enforcement officer issues the traffic citation and continues next through the adjudicatory process. The cycle is complete when the SDLA receives a conviction notice, updates the CDL holder's driving record, and imposes any sanction. The cycle begins again with a law enforcement officer verifying CDL status when conducting a roadside enforcement action.
