Greece Category C Theory study guide
Greece Category C Theory · Work through your exam, one topic at a time.
The Greek Category C theory examination is the written knowledge test that a candidate must pass to obtain a professional driving licence for rigid lorries above 3.5 tonnes maximum authorised mass in Greece. It is aimed at people who want to work as lorry drivers, whether entering the profession for the first time or upgrading from a Category B car licence, and it is administered by the Greek public authorities responsible for driving licences and road transport. The Greece Category C Theory study guide has 8 sections and about 4,900 words.
01Road Traffic Law and the Highway Code (Κώδικας Οδικής Κυκλοφορίας)
This domain tests the Κώδικας Οδικής Κυκλοφορίας (ΚΟΚ, Law 2696/1999 as amended) as it applies to a heavy goods vehicle rather than a car. Questions focus on licence scope, the paperwork that must be in the cab, the speed and alcohol limits that bind professional drivers, priority at junctions, and the sanctions that follow an offence.
523 words, about 3 min02Road Signs, Markings and Signals
This domain checks whether you can read the signing system fluently at lorry speed: which sign family a shape belongs to, which restrictions are aimed at your vehicle rather than at cars, what each road marking permits, and how signals from lights and officers override everything else. Danger signs: equilateral triangle, red border, white ground, black symbol; they warn of a hazard ahead and are placed in advance of it, closer in built-up areas than on rural roads.
487 words, about 2 min03Safe Driving Behaviour
This domain examines the everyday habits that decide whether a loaded lorry arrives safely: speed choice for the conditions, following distance, lane and overtaking discipline, correct use of lights and signals, personal fitness to drive, and the standard procedure after a motorway breakdown. Speed must allow you to stop within the distance you can see to be clear.
502 words, about 3 min04Hazard Perception and Defensive Driving
This domain is assessed through the hazard perception component and scenario questions, and it tests whether you spot developing hazards early and choose a plan that leaves you an escape route. A professional driver is expected to assume that the other road user has not seen the lorry, not the reverse.
506 words, about 3 min05Vehicle Loading, Dimensions and Mass Limits for Category C
This domain tests whether you can load and operate a lorry within its legal and structural limits: mass definitions, axle loads, the harmonised dimension limits, load distribution and securing, and what happens when a weighbridge shows an overload. Kerb mass (tare) is the empty vehicle; maximum permissible mass (MMA) is the manufacturer's and legal ceiling including load, fuel and driver; payload is MMA minus kerb mass.
475 words, about 2 min06Driving and Rest Time Rules
This domain covers Regulation (EC) 561/2006 and its enforcement in Greece: daily, weekly and fortnightly driving limits, the break rule, daily and weekly rest, multi-manning and how the limits interact with other work such as loading. Maximum 9 hours driving per day, extendable to 10 hours twice in a week.
454 words, about 2 min07Tachograph and Transport Documentation
This domain tests practical tachograph operation under Regulation (EU) 165/2014 and the paperwork a Category C driver must be able to produce at a roadside check in Greece. Digital and smart tachographs record speed, distance, driving, other work, availability and break.
482 words, about 2 min08Vehicle Mechanics, Inspection and Pre-Departure Checks
This domain tests the daily walk-around and the mechanical knowledge a Category C driver needs to refuse an unsafe vehicle: brakes and air system, tyres and wheels, lights, steering, couplings and fluids, plus the statutory inspection regime. Check tyres and wheels first: tread depth of at least 1.0 mm for heavy vehicles, correct pressure when cold, no cuts, bulges, exposed cords or objects, and sufficient spacing between twins.
