Final answer:
Federally regulated drivers required to maintain a daily log must have their daily logbook with them. The logbook records hours spent in various activities to ensure compliance with HOS regulations. Maps, task lists, or vehicle registration are not required for the daily log.
Step-by-step explanation:
Under federal regulations, drivers who are required to keep a daily log must have the daily logbook in their possession to comply with the Hours of Service (HOS) Regulations. The daily logbook is a record that details the hours spent driving, on-duty but not driving, off-duty, and in the sleeper berth. It is not necessary for drivers to carry a map of the route, a list of daily tasks, or the vehicle registration as part of the daily log requirements. The logbook ensures that drivers adhere to the legal limits on driving time and must be present if requested by law enforcement or Department of Transportation (DOT) inspectors.
