AF Commercial Driving Theory case studies
AF Commercial Driving Theory · Put your knowledge to work in context.
The AF Commercial Driving Theory exam is a multiple-choice knowledge test for candidates seeking to drive commercial vehicles professionally. It assesses whether a driver understands the rules, signage, vehicle condition requirements and compliance obligations that apply to heavier and larger vehicles in everyday working conditions. The syllabus is organised into eight domains: road traffic rules and regulations carry the largest share, followed by traffic signs, signals and road markings, vehicle safety, inspection and maintenance, and driver hours, rest periods and fitness to drive. Load securing, weights and dimensions, hazard perception and defensive driving, incidents and first aid, and vehicle documentation and regulatory compliance make up the remainder. The AF Commercial Driving Theory case studies are 5 cases and about 1,754 words.
