The U.S. Department of Transportation (DOT) has log book requirements. The requirements ensure drivers are not driving without proper rest breaks. Every driver operating a commercial motor vehicle (CMV) must track their duty status for each 24-hour period (off, sleeper berth, driving or on-duty not driving) using either an automatic on-board recording device or “Daily Log, Form MCS-59” or the “Multi-day Log, Form MCS-139 and 139A,” in duplicate. The driver must record the city (or truck stop, highway milepost or intersection) when reporting for work, starting to drive, on-duty but not driving, or released from work.

In addition to the duty status grid, the daily log form must include:

  • Date
  • Daily miles that are driven
  • Vehicle number
  • Carrier name
  • Driver’s signature
  • 24-hour starting time
  • Main office address
  • Co-driver’s name, if applicable
  • Total hours and shipping document numbers (or the name of shipper and commodity).
  • The driver’s activity record
  • Be legible and in the driver’s handwriting.
  • The seven or eight-day time period for the driver retaining the log begins from the workplace.
  • Any additional comments if necessary

Retention of Records 

Employers must keep drivers’ duty status records (and other supporting documents) for six months. Drivers must carry a copy of their duty status records for the previous seven days and provide them for inspection. Drivers also must give or mail their original duty status records to their employers within 13 days of completing them.

If a driver works for more than one employer in a 24-hour period, they must give a copy of their duty status record to each one. The record must account for all time during the 24-hour period and include the name of the employer during the period and the beginning and end time for each employer. Drivers working for more than one employer must report their total time on duty during the previous seven days to prevent exceeding the allowed work periods.
