Which of the following must be included in a CMV DR-18 report if available?

• A. The date and nature of the offense
• B. The commercial driver's license number and social security number
• C. The vehicle was a CMV
• D. The hazardous materials indicator

Answer: (B)

Driver identification is the focus of this form. The CDL number serves as the primary identifier for a commercial driver, linking to licensing status and driving history. If available, the Social Security number provides an additional universal identifier to confirm the driver’s identity across states and records, helping to prevent mix-ups when names are similar or records come from different sources. Other data like the fact that the vehicle is a CMV or a hazardous materials indicator are conditional or contextual and not universally required for identification in every DR-18 report. So, when possible, including both the CDL number and the Social Security number ensures accurate identification.
