The ALRTA says the Queensland rule change means B-triple combinations can adjust their speed
The Queensland Transport and Main Roads (TMR) department has recently made amendments to its B-triple road train combinations.
The Australian Livestock and Rural Transporters Association (ALRTA) announced in its weekly newsletter that the TMR changed its Transport Operations (Road Use Management-Road Rules) Regulation 2009 (Queensland Road Rules) for B-triple combinations.
The changes include the definition of a B-triple road train combination in the Queensland Road Rules aligning with the Heavy Vehicle National Law while allowing B-triple road train combinations to be permitted to travel at speeds of up to 100 kilometres per hour.
The ALRTA warns that all other road train combinations are only permitted to travel at speeds of up to 90 kilometres per hour.

Under the new law, B-triple road train combinations are a prime mover towing three semitrailers.
Under the Queensland Road Rules, the first semitrailer must be attached directly to the prime mover by a fifth wheel coupling, while the second semitrailer has to be mounted on the rear of the first semitrailer by a fifth wheel coupling on the first semitrailer.
Finally, the third semitrailer has to be mounted on the back of the second semitrailer by a fifth wheel coupling.
