Final answer:
Drivers of property-carrying CMVs are required to complete and sign a DVIR at the start of their work day, whenever a defect or deficiency is discovered or reported, and when a change of duty status is made, every three hours or every 150 miles.
Step-by-step explanation:
The regulations require drivers of property-carrying CMVs to complete and sign a DVIR under the following circumstances:
- At the start of their work day for each vehicle they intend to operate during that shift.
- Whenever a defect or deficiency is discovered or reported.
- When a change of duty status is made, every three hours, or every 150 miles, whichever comes first.
Therefore, options A, B, and C are correct answers.
Option D, at the end of their work day for any vehicle or equipment they used during that shift, is not accurate.
