Quick checklist

  • Keep your own DQ file if you are the driver for your authority.
  • Save every maintenance record by truck and trailer.
  • Review ELD logs weekly.
  • Keep insurance, authority, registration, and UCR records in one folder.
  • Ask drug testing and ELD vendors for audit-ready records before the deadline.

Why this matters

A one-truck business still has multiple record categories. The goal is not a big office system; it is a small packet that can be maintained after every trip and repair.

What to prepare

Area Records to gather
Single-truck packet
Weekly routine
  • Certify logs
  • Save fuel and trip support records
  • File repair receipts by unit
  • Check mail and portals for official notices

Common gaps

  • The owner assumes driver qualification rules only apply to hired drivers.
  • Receipts are kept in the truck but not copied to a file.
  • ELD records are never exported until the audit.
  • Insurance and authority documents are scattered between email and glovebox copies.

Before / During / After audit

Before

  • Build a one-truck packet.
  • Request vendor records early.
  • Run an ELD export test.

During

  • Use the packet index to keep answers focused.
  • Keep vendor contact information nearby.

After

  • Update the packet each Friday or after each trip cycle.
  • Store digital copies outside the truck.
