Transport and Main Roads Queensland (TMR) has recently made amendments that impact B-triple road train combinations.
The amendments refer to the Transport Operations (Road Use Management–Road Rules) Regulation 2009 (Queensland Road Rules) and came into effect on September 9.
The changes are as follows:
- The definition of a B-triple road train combination in the Queensland Road Rules will align with the Heavy Vehicle National Law .
- B-triple road train combinations will be permitted to travel at speeds of up to 100 km/h (all other road train combinations are only permitted to travel at speeds of up to 90 km/h).
The definition of a B-triple road train combination in the Queensland Road Rules is a prime mover towing 3 semitrailers:
a) the first semitrailer being attached directly to the prime mover by a fifth wheel coupling; and
b) the second semitrailer being mounted on the rear of the first semitrailer by a fifth wheel coupling on the first semitrailer; and
c) the third semitrailer being mounted on the rear of the second semitrailer by a fifth wheel coupling on the second semitrailer.
