HTV Driving Theory case studies
HTV Driving Theory · Put your knowledge to work in context.
The HTV driving theory test is the knowledge-assessment step for drivers who want to operate heavy transport vehicles - tractor-trailers, rigid lorries and similar high-mass combinations. It is aimed at learner drivers progressing to a heavy-vehicle licence, at drivers adding a heavier class to an existing licence, and at fleet operators who need staff to demonstrate formal road-knowledge competence. The test is computer-based and multiple choice. It examines road traffic law, signs, markings and right-of-way as they apply to large vehicles; the condition and systems of the vehicle itself, from pre-trip inspection and defect reporting through to braking and load securement; and the judgement a heavy driver needs - hazard perception, speed and space management, driver hours and emergency response. The HTV Driving Theory case studies are 5 cases and about 2,442 words.
