Heavy Combination (HC)

TLILIC3017B Licence to drive a heavy combination vehicle


On completion of your training and assessment you will be able to drive a heavy combination vehicle including:

  • Prime mover with a minimum of three axles and a semi-trailer with a minimum of two axles (vehicle must have a GVM rating of at least 24 tonnes)
  • Heavy rigid vehicle towing a trailer (trailer must have at least two axles and a GVM of 12 tonnes or more)


Synchromesh Gear Box is the same gearbox used in a manual car. This is the gear box the trucking industry has adopted, along with automated manuals and automatics. More modern trucks are equipped with these gear boxes and are easier to drive than Constant Mesh Gear Boxes.

  • Once you pass your licence tests your licence will be restricted to ‘Condition B’. This allows you to drive an automatic and/or a synchromesh gear box.

Constant Mesh Gear Boxes are also known as “Road Ranger” or “Crash Box”. These gear boxes are difficult to drive and previous experience is an advantage. Trainees must be proficient at the double declutch required for changing gears.

  • Once you pass your licence tests your licence will have no gear box restriction conditions. You will also be qualified to drive heavy vehicles with an automatic and/or a synchromesh gear box.


  • You must be at least 20 years old
  • You have held a current NSW MR or HR truck licence for a minimum of 1 year
  • Synchromesh Truck – you must know how to reverse a trailer
  • Constant Mesh Truck (Road Ranger) – you must know how to operate a Constant Mesh gearbox and reverse a trailer

Note: P2 licence holders cannot upgrade to this class
