Buying a safe heavy vehicle

The booklet, Safety Technologies for Heavy Vehicles and Combinations [PDF 627 Kb] provides information on crash avoidance technologies, systems that improve driver safety and comfort, and systems that also improve the safety of other road users.

Crash avoidance technology systems, include:

  • Electronic Stability Control
  • Trailer Roll Stability
  • Autonomous Emergency Braking
  • Electronic Braking Distribution
  • Wheel nut indicators and locks
  • Disc brakes
  • Vehicle visible markings
  • Tyre pressure management devices
  • Reversing safety
Protective systems that improve driver and occupant safety, and the safety of other road users, include:
  • Suspension seats with integral seat belts
  • Underrun protection devices
  • Automatic traction control
  • LED Lighting
  • Airbag systems
  • Cabin strengthening
  • Fire suppression system
Technology that can improve the comfort of the driver’s workplace, include:
  • Treatments to reduce in-cabin noise levels
  • Suspension systems that improve the ride quality for the driver
  • Ergonomic cabin design
  • Intelligent speed adaptation warning system

Aftermarket Improvements

While most of the safety technologies listed above can only be fitted on new heavy vehicles, some systems can be retrofitted to existing heavy vehicles. These include:
  • Tipping-trailer stability protection system
  • Load proportioning brake value system – only for vehicles with airbag suspension
  • Wheel nut indicators and locks
  • Disc brakes
  • Vehicle visibility markings
  • Tyre pressure management devices
  • Suspension seats with integrated seat belts
  • Seat belt wearing monitors
  • Automatic brake adjustment devices
  • LED lighting
  • Intelligent speed adaptation warning system
  • Fire suppression systems
To further improve the safety of your vehicle fleet, transport companies could also consider retrofitting the following technologies:
  • Automatic incident notification and routine event reporting system
  • Alcohol ignition interlock

Retrofitting technologies on existing heavy vehicles should only be done by a qualified professional technician and some may require an Authorised Vehicle Examiner (AVE) approval certificate, commonly referred to as an engineering approval certificate. Further information about heavy vehicle modification and AVEs is available from the National Heavy Vehicle Regulator website (External link)
