The EWD Standards set minimum performance requirements for an electronic recording system to be approved for use as an EWD.

EWDs may provide extra commercial features as long as they don't interfere with the regulatory functions of the EWD.

EWD is short for Electronic Work Diary and is an electronic recording system approved by the NHVR for recording the work and rest times of a heavy vehicle driver as a voluntary alternative to the written work diary.

  • level of services that are requested by the transport operator
  • associated training
  • number of units required.

The provisions for EWDs are included in Chapter 6 Vehicle operations—driver fatigue of the Heavy Vehicle National Law (HVNL).
