Final answer:
D. 14. To avoid violations, commercial motor vehicle drivers must keep their record of duty status up to date. They need to have the previous 14 consecutive days' records in their possession and available for inspection.
Step-by-step explanation:
In this context, the subject of keeping a record of duty status current is related to the Trucking Industry and Compliance Regulations. Specifically, it pertains to the Hours of Service (HOS) regulations for commercial motor vehicle drivers. These regulations are enforced by the Federal Motor Carrier Safety Administration (FMCSA) in the United States.
The correct answer to the question is D. 14. According to the HOS regulations, commercial motor vehicle drivers must have the previous 14 consecutive days' record of duty status in their possession and available for inspection at all times.
Failure to comply with these regulations can lead to penalties, violations, and potential suspension of driving privileges.
