Do you find logbooks confusing? You're not alone

FIND logbooks confusing? You're not the only one. A recent post on Facebook about how to count time led us to contact the NHVR to clarify a few things.

How are 24 hour periods counted?

  • The Heavy Vehicle National Law limits counting of 24 hour periods to only those 24 hour periods commencing at the end of a relevant major rest break (section 247 (b)).
  • Page 22 of the work diary instructions states the different relevant major rest breaks for drivers depending on their work and rest option.
  • There is no way to reset or end a 24 hour period. A 24 hour period only ends 24 hours after it started (ie - the same time on the following day).
  • A relevant major rest break, is any period of rest of at least 5 or 7 continuous hours (depending on your work and rest option).
  • The 24-hour period ends 24 hours later (at the exact same time on the following day), regardless of how much work you have done or rest you have taken during that time.
  • It is important to remember that the 5 or 7 continuous hour period for a major rest break is the minimum amount of continuous rest required in a 24-hour period.

What happens if a driver has another relevant major rest break within the current or first 24 hour period?

  • Having another, second relevant major rest break starts a second, overlapping 24 hour period.
  • It does not reset or end the first 24 hour period.
  • Any work done by a driver after the second relevant major rest break counts toward both 24 hour periods.
  • Drivers must not work after the second relevant major rest break if doing so would cause them to exceed their work limit for the first period.
  • If work after the second relevant major rest break causes the driver to exceed their work limit in the first 24 hour period they would be breaching the law.

Some common questions:

  • Does a major rest break reset my 24-hour period?

No. The law doesn't allow you to reset or shorten a 24-hour period. A major rest break during this time will only start another 24-hour period. This means that a solo driver (under Standard Hours) who works 12 hours in a 24-hour period must also have a total of 12 hours rest.

  • Can I start working again straight after taking a major rest break?

That depends on how many hours you worked before taking the break. If you have worked less than your maximum work hours for that 24-hour period, you can work any remaining hours after finishing your break.
