Greece Category D Theory common mistakes
Greece Category D Theory · Understand the traps and how to avoid them.
When a tachograph chart or digital record shows a break, the candidate counts the break as driving time or forgets that a break may be split into two parts of at least 15 minutes followed by 30 minutes, and answers a calculation question with the wrong total.
Candidates memorize '45 minutes' as a single block and never practise splitting it across a duty period, so under exam pressure they add the break into the driving total or apply the split in the wrong order.
What to do instead
Work through at least ten written duty timelines: mark each driving segment, each break, and each rest, then verify that the 15+30 split always follows the 15-minute part first. Practise converting the same timeline into a 4.5-hour driving check and a 9-hour or 10-hour daily driving check separately.
The candidate reads a road sign or marking as its general shape suggests rather than as Greek law defines it, for example treating a blue circular sign as a prohibition instead of a mandatory instruction, or missing the difference between a warning triangle and a danger sign with supplementary plate.
Shape-and-colour logic is learned quickly but then over-applied; candidates stop checking the supplementary plates and the Greek-language text under the symbol, which often changes the meaning (time limits, vehicle categories, exemptions).
What to do instead
Build a one-page table of sign families by shape and colour, then add a column for supplementary plates. For every sign in the table, write one sentence on what it requires and which vehicle categories it applies to. Re-test yourself by covering the symbol and naming the rule from the plate alone.
On hazard-perception items the candidate answers with what the driver should do after the hazard is obvious, instead of identifying the earliest clue in the described scene (a pedestrian hesitating at a crossing, a bus stopped without indicators, a wet patch on a bend) and the speed or space adjustment it demands.
Candidates revise rules rather than scan technique, so they jump to the correct final action and lose the marks attached to anticipation, observation sequence, and the decision to slow before the hazard develops.
What to do instead
Practise the mirror–signal–manoeuvre sequence aloud on paper scenes: name the clue, name the mirror check, name the speed change, then name the action. For each written scenario, write the earliest clue and the latest safe point to act. Do this for twenty short scenarios across urban, rural, and motorway settings.
The candidate mixes up the permitted maximum authorised mass, the maximum permissible payload, and the actual laden mass when a question asks whether a load is legal, and then applies the wrong limit to the vehicle category.
The Greek terms for these masses look similar and candidates learn them as vocabulary rather than as a calculation, so they pick the number that appears in the question instead of the number the law sets for that category.
What to do instead
Learn the three definitions with a worked example each: a vehicle with a stated maximum authorised mass, a stated kerb mass, and a stated payload. Compute the payload from the other two and check it against the category limit. Then do the same for an axle-load question and a train-weight question.
The candidate answers first-aid questions by describing hospital treatment or by moving a casualty immediately, rather than following the protect–alert–rescue order and the rule that an unconscious but breathing casualty is placed in the recovery position.
First aid is studied last and briefly, and candidates rely on general intuition; they forget that the exam tests the sequence of actions at the scene, the correct emergency number, and what not to do (do not give drink, do not remove a motorcyclist's helmet unless the airway demands it).
What to do instead
Memorize a fixed four-step script: secure the scene and warn traffic, call the emergency services with location and casualty count, check response and breathing, then act (recovery position, control bleeding, keep warm). Rehearse the script on five written scenarios including a motorcyclist, a trapped occupant, and a casualty not breathing.
The candidate treats the pre-trip check as a list of items to name rather than a sequence with pass criteria, so questions about tyre tread depth, brake air-pressure warning, or tachograph calibration validity are answered with a vague 'check it is in order'.
Checklists are memorized as headings without the numeric limits and without the order in which checks are made, so the candidate cannot answer a question that supplies a measurement and asks for a decision.
What to do instead
Write the pre-trip check as a numbered sequence with a number beside every item: minimum tread depth for the vehicle category, correct tyre pressure source, brake test method before moving off, lights and indicators, load securing, tachograph calibration and seal. Then answer ten questions that give a measurement and require a pass or fail judgement.
The candidate confuses the rules on daily and weekly rest with the rules on breaks, and answers that a reduced daily rest is always allowed or that weekly rest can be compensated at any later date without the required compensating rest attached to it.
Breaks, daily rest, and weekly rest are revised as one block of numbers, and the conditions attached to reductions (the compensating rest, the limit on reductions between weekly rests) are dropped under time pressure.
What to do instead
Draw a three-column sheet: breaks, daily rest, weekly rest. In each column record the normal duration, the permitted reduction, the compensation rule, and the time limit for taking compensation. Then annotate a seven-day rota and mark every reduction with its compensation.
The candidate answers passenger-carrying questions using lorry or car assumptions, for example on the number of passengers permitted, on standing passengers, on the carriage of luggage in the aisle, or on which documents must be carried on the vehicle during a national or international journey.
Category D candidates often revise from general driving material and never separate the bus-specific obligations: the passenger count against the registration document, the prohibition on obstructing the aisle and emergency exits, and the documents that must be on board.
What to do instead
Make a dedicated bus-operations sheet: permitted passenger number and how it is shown, rules on standing passengers and aisle clearance, emergency exit access, and the document set for national and international journeys. Test yourself by describing a loading situation and stating whether it is legal and why.
The candidate gives an environmental or fuel-efficiency answer that is only a slogan ('drive smoothly') instead of naming the specific techniques the exam rewards: early upshifting, reading the road to avoid braking, correct tyre pressure, avoiding unnecessary idling, and using engine braking and cruise control appropriately.
Environmental driving is treated as common sense and revised without the technical vocabulary, so answers lack the specific action the marking scheme expects and cannot be distinguished from a guess.
What to do instead
List eight named techniques with the mechanism for each (why early upshifting reduces consumption, why idling wastes fuel, how under-inflation raises rolling resistance). Then answer ten scenario questions by naming the technique and the saving it produces, not by describing a driving style.
The candidate answers professional-conduct and accident-procedure questions by describing what feels fair rather than the legal duty: failing to state the obligation to stop, to give assistance, to exchange particulars, to report to the police within the required time, and to secure the scene and warn other traffic.
Conduct is revised as attitude rather than as legal duties, and the accident procedure is remembered as 'call the police' without the order of steps, the particulars to exchange, and the duty to remain at the scene.
What to do instead
Write the accident procedure as a fixed ordered list from stopping and securing the scene through assistance, exchange of particulars, police notification, and written statement. Add the professional-conduct duties separately: fitness to drive, no alcohol or drugs, no mobile phone use, courtesy to passengers and other road users, and correct handling of complaints. Rehearse both lists on written scenarios.
