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 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.
