Truck Log Book

A truck log book, also known as a work diary, is a document truck drivers must keep to show their compliance with the work and rest hours regulations in Australia according to the Heavy Vehicle National Law.

The work diary is in the form of empty sheets that drivers must fill out each day with the start of the working day, driving, rest hours and more. Of course, there are some exceptions to the drivers that must keep a truck log book.

When to keep a truck log book

The Heavy Vehicle National Law (HVNL) sets out rules on who must keep a truck log book and in which instances.

These laws relating to work diaries currently apply in NSW, QLD, SA, TAS, ACT and VIC.

You must keep a truck work diary if you drive a fatigue-regulated heavy vehicle (vehicles with a gross mass over 12 tonnes and busses over 4.5 tonnes for more than 12 people) and:

  • Operate more than 100 kilometres from your home base under standard hours.
  • Work under Basic Fatigue Management (BFM), or
  • Work under Advanced Fatigue Management (AFM)

Note that even if most of the time you operate under standard hours within a local, 100 km radius from your home base, but have days where you drive farther, you will need to keep a log book for these days.

How to fill out a truck driver log book in Australia

You must always fill out specific details of your work day in order to maintain a compliant work diary. The first part of your truck log book contains data for driver identification, specifically your name, driver's license number and the vehicle number plate. You must also fill out the date, week and time zone of your home base and the hours under which you are operating, e.g. standard, AFM or BFM.

Throughout your work day, you must fill out your work and rest hours at every switch between rest and work, an odometer reading of your vehicle and the location of the change. Truck log book regulations stipulate you should be as specific as possible when you write down the location.

Finally, you calculate your total driving and rest hours for the date and sign the work diary.

Keeping your truck log book

You must have your truck log book with you at all times, even if on some days you only operate in your local area. If you finish the sheets on your work diary and are filling out a new one, you will still need to keep the completed truck log book with you for 28 days.

Every page of your work diary has an Original, and two Copy pages - a yellow and a pink one.

You must keep the Original page in your truck log book, and provide the yellow copy of your daily work diary to your record keeper. The pink Copy page can be used if for example, you complete work for two separate employers in one day, or if an authorised officer requests it.

Trucks that need to keep a log book are trucks with a gross vehicle mass of over 12 tonnes.
You can purchase a truck driver’s log book directly from the National Heavy Machine Regulator (NHVR), or their official distributors. Other outlets you can find truck log books include stationery shops or online shops.
