Countries like Australia where everything from sports to movies, from tourism to driving every single thing is so particular which require proper authenticated licenses, permissions and regulations. In almost every western country especially in Australia driving is sensitive hence rules are quite rigid there, separate rules and regulations for car license, LR license, MR license and HR license, in addition to this they have defined separately what specifications of vehicle considered as LR, MR and HR this brings us to the discussion of multi combination/b doubles.

For those who don’t know about B doubles, it’s a hybrid version of truck and trailer in which there is a prime mover to pull two trailers attached behind the mover. In this field Australia has violated some rules and has established B doubles, B triples, double-B doubles and 2 AB quads and these kinds can be witnessed generally in Australia. Usually B doubles are 90 to 93 ft. long and b triples are 110 to 114 ft. long, the actual term B double (where B stands for Bogie). HC license covers the driving capacity of a B double since the B double is a kind of vehicle described in HC specs, 3 or more axles and weight more than 7500 kg. Driving skills required to drive this giant vehicle are stricter than any normal vehicles, because it’s like a long metal snake which a driver is driving on the road. Extra containers or load/weight on the trailer makes it even more difficult for the person to handle a B double. According to the data collected from the driving schools in Australia it has been concluded that, the most difficult part for most of the drivers is to reverse the B-double licence Gold Coast and B triple truck, as it requires critical turning skills, extreme road sense and patience because a single mistake can cause massive destructions in Australia heavy loads of oil and other gigantic heavy containers are transported from one place to another hence the rules of B doubles are different, lanes are separate in order to save small cars and all other vehicles.

A b double driver has to adapt left lane always, driving schools in Australia usually focus on techniques like move off in the traffic flow, make left and right turns (especially narrow and wide roads among divided roads and crossings), uphill and downhill, appropriate shifting of gears and maintenance of speed under all conditions, braking techniques (since braking is an important factor while driving any vehicle especially B doubles) speed maintenance and braking both are important since applying brakes abruptly may cause skidding and destructive flipping of weights (behind the prime mover). Even during final driving test one needs to be stay alert and vigilant while changing gears, accelerating and steering.
