  • 15 m radius, 5 to 15 km/h
  • 20 m radius, 15 to 20 km/h
  • 30 m radius, 20 to 30 km/h

A-double (Type I road train) (36.2 m)1

  • 15 m radius, 5 to 15 km/h
  • 20 m radius, 15 to 20 km/h
  • 30 m radius, 20 to 30 km/h

A-triple (Type II road train) (53.4 m)2

  • 15 m radius, 5 to 15 km/h
  • 20 m radius, 15 to 20 km/h
  • 30 m radius, 20 to 30 km/h.

  1. Note: the maximum length permitted for an A-double is 36.5 m, however the overall length of the vehicle combination is 36.2 m which reflects typical dimensions.

  2. Note: the maximum length permitted for an A-triple is 53.5 m, however the overall length of the vehicle combination is 53.4 m which reflects typical dimensions.
