A medium rigid (MR) license in Australia allows holders to operate vehicles with two axles which weigh more than 8 tonnes, as well as any trailer which weighs under 9 tonnes. The MR license also allows drivers to operate any LR class vehicle. In Australia, the MR license is one of the most common license upgrades because it covers a wide variety of buses and trucks. It is not difficult to obtain this upgrade due to the gearbox configuration similarities between LR and MR vehicles.
There are many training courses which drivers can take to help them obtain an MR license. These programs can teach people who are experienced in driving manual cars to drive MR class vehicles in a single day. Training courses rely on the RTA competency standards to train and assess student drivers.
