How to Fill Out a DOT Log Book for Truck Drivers

Filling out a DOT log book means completing a paper record of duty status for each 24-hour period: identifying yourself, your carrier, and your vehicle at the top; drawing your time across a four-row, 24-hour grid; noting the city and state at every status change; totaling your hours to exactly 24; and signing the sheet before it goes to the carrier. The rules for what the form must contain and how it must be maintained sit in 49 CFR § 395.8.¹ Use blue or black ink. Pencil will not survive a roadside inspection.

Complete the Header First

The top block of the log sheet ties the record to a specific driver, carrier, vehicle, and load. Pre-printed booklets from truck stops or your carrier give you a labeled box for each item, but nothing gets filled in unless you do it.

Every log needs:

The date — month, day, and year that begin the 24-hour period.
Total miles driven during the period, from your starting odometer to your ending odometer.
Vehicle identification for every truck, tractor, and trailer you operated. Use the carrier’s unit number, or the license plate and state. If you swapped units mid-shift, list all of them.
Carrier name and main office address, written exactly as they appear on official registration. Mismatches invite scrutiny.
Shipping document number, or the shipper’s name and the commodity, linking the log to the load.
The 24-hour period starting time set by your employer for your home terminal — midnight, noon, or whatever hour the terminal uses. Every driver working from that terminal uses the same starting time.¹
Co-driver’s name, if you are running as a team.

Log every entry in your home terminal’s time zone, no matter where you actually are that day.² If your terminal is on Central time and you cross into Eastern, the log stays on Central. That keeps the record consistent when inspectors compare it against fuel receipts and toll timestamps.

Draw Your Time on the 24-Hour Grid

The grid is the core of the log. It spans a full 24 hours in one-hour increments across the top, with four horizontal rows for the four duty statuses defined in 49 CFR § 395.8(b).¹

The four rows are:

Off Duty (OFF) — you are completely relieved of all work responsibility.
Sleeper Berth (SB) — rest time inside the truck’s sleeping compartment. Only use this row if the vehicle has one.
Driving (D) — any time the vehicle is in motion under your control.
On Duty Not Driving (ON) — work tasks that are not driving: loading, unloading, fueling, inspecting, paperwork.

To record your day, draw a continuous horizontal line along the row that matches your current status. When you change status, drop a vertical line from the row you were on down or up to the new row, at the exact time of the change. Keep going. What you end up with is a stair-step path across the 24 hours that shows an inspector the whole shift at a glance. Precision is not optional here. Inspectors will hold your grid against GPS traces, fuel transactions, and toll data.

Note the Location at Every Status Change

Every vertical line on the grid needs a matching city and state (or province, in Canada) in the remarks section beside or below the grid.¹ Stop for fuel, draw the line to On Duty Not Driving, write the city and state. Get back in, draw the line to Driving, no new location needed until the next change. Those location entries are what let an inspector confirm your distances are physically possible in the time you claim. Skipping them is one of the most-cited form-and-manner violations on the road.

Total the Hours and Sign the Sheet

At the end of the 24-hour period, add up the time you spent in each status and write those totals in the right-hand column next to the grid. The four numbers have to add up to 24. If they do not, something on the grid is wrong. Enter your ending odometer, calculate total miles driven, and put that number in the header.

Then sign. Use your legal name or name of record. Your signature certifies that every entry is true and correct.¹ An unsigned log is treated as if it does not exist.

Paper logs are filled in duplicate. The original goes to your motor carrier within 13 days of the period it covers. The carbon copy stays with you.¹

Keep the Current Day and the Previous 7

Any time you are on duty, you must have your log for the current day plus the prior 7 consecutive days available for inspection. That is an 8-day window, and it exists so enforcement can verify the weekly cumulative limits.¹ A gap in that window is a citable violation on its own, separate from anything wrong on the individual sheets. Keep them in a folder or binder where you can hand the whole set over in one motion.

Check the Log Before You Sign

The same errors turn up in roadside inspections again and again. Run through them before your signature goes on the sheet.

Missing locations. Every vertical line on the grid needs a city and state in the remarks. This is the most common form-and-manner miss.
Blank total miles. The mileage box at the top gets skipped often. Subtract starting odometer from ending odometer and write it in.
Log not current. Your entries have to be up to date through your most recent status change. If you stopped driving two hours ago and the grid still shows you in the Driving row, the log is not current.
Missing days in the 8-day window. Today plus the previous 7. Count them.
Hours that do not total 24. Off Duty plus Sleeper Berth plus Driving plus On Duty Not Driving equals 24, always. If it comes out to 22 or 26, the inspector will find it before you do.

The fastest quality check is to look at the finished sheet the way an inspector would seeing it for the first time. Header complete. Every vertical line paired with a location. Totals equal 24. Get those three right and most citations never happen.

When Paper Logs Are the Required Record

Since December 2017, most interstate carriers have run on Electronic Logging Devices, and paper is no longer the everyday record. It still applies in specific situations. Drivers operating a commercial motor vehicle manufactured before model year 2000, as identified by the VIN on the registration, are allowed to record duty status manually.³ Short-haul drivers who stay within a 150 air-mile radius of their normal work reporting location, return within 14 consecutive hours, and meet off-duty rest requirements are exempt from keeping a daily log at all, though the carrier still tracks time records.⁴

The most common reason for a paper log is an ELD malfunction. When the device fails, note the malfunction, give written notice to your motor carrier within 24 hours, and start recording duty status on paper.⁵ If the malfunction prevents the ELD from displaying the previous seven days, have printed copies or an electronic backup available for inspectors.⁶ During the entire malfunction period, the paper log is your legal record of duty status and needs the same attention as any other day’s entry.
