This unit focuses on the operation of vehicle combinations, including different types of trailers and semitrailers (Anhänger, Sattelanhänger). It details the correct procedures for coupling and uncoupling (Kuppeln) and explains the dynamics of articulated vehicles. Key topics include the risks of jackknifing, managing off-tracking (trailer cut-in), and strategies for safe reversing with a trailer.

Prepare for your Austrian heavy-goods vehicle theory exam with this structured curriculum. The course covers all essential knowledge areas, including vehicle dimensions, load securing (Ladungssicherung), advanced braking systems, and specific rules for driving on motorways and alpine routes. You will learn to interpret heavy vehicle-specific road signs, manage vehicle stability, and understand the legal responsibilities of a professional driver, ensuring you are fully prepared for both the test and safe operation on Austria's roads.
