Traffic Law and Road Signs

  • Greece drives on the right; overtaking is on the left except when traffic is in ordered lanes and the left lane is occupied by a turning vehicle.

  • Priority to the right applies at uncontrolled intersections; a driver leaving a private road, dirt track, or parking area must yield to all traffic already on the public road.

  • Sign shapes: red-bordered triangles warn, red-bordered circles prohibit or restrict, blue circles command, blue squares and rectangles inform, octagons stop.

  • A STOP sign (octagon, 'STOP') requires a complete halt at the stop line; a yield triangle requires giving way without necessarily stopping.

  • Speed limits for lorries over 3.5 t: 80 km/h on ordinary roads outside built-up areas, 90 km/h on motorways, 50 km/h in built-up areas unless signed otherwise.

  • Minimum following distance is at least the distance covered in 2 seconds; in tunnels and on bridges a fixed gap must be kept where signed.

  • Safety belt use is mandatory for driver and all passengers; children under 12 and under 150 cm need an approved restraint system.

  • Alcohol limit is 0.50 g/l blood alcohol for category B and C/D licence holders; 0.20 g/l applies to professional drivers of lorries and buses and to novice drivers.

  • Using a hand-held mobile phone while driving is prohibited; only hands-free equipment is allowed.

Road Safety and Hazard Perception

  • Stopping distance = reaction distance + braking distance; braking distance grows with the square of speed, so doubling speed quadruples braking distance.

  • On dry asphalt a loaded lorry's braking distance at 80 km/h is roughly 55-60 m; on wet road add about 50%, on ice multiply by up to 10.

  • Total stopping distance at 50 km/h on dry road is about 27 m (14 m reaction + 13 m braking); at 90 km/h it is about 90 m.

  • A lorry's blind spots extend along both sides and directly in front; a cyclist or pedestrian within 2 m of the cab front is invisible to the driver.

  • When a bus or lorry ahead brakes suddenly, treat it as a signal that a pedestrian or obstacle is crossing in front of it.

  • In fog use dipped headlights and fog lamps, reduce speed so that you can stop within the visible distance, and never use rear fog lamps in clear conditions.

  • Hydroplaning begins at roughly 80 km/h on a film of water 2 mm deep; ease off the accelerator and do not brake hard.

  • On a downhill gradient, select a low gear before descending and use engine braking; continuous service braking overheats drums and fades the brakes.

  • Overtaking a long vehicle needs a clear view far ahead: the overtaking distance at 80 km/h versus 60 km/h exceeds 300 m.

Vehicle Categories

  • Category B: motor vehicles up to 3,500 kg maximum authorised mass with no more than 8 seats excluding the driver, optionally with a trailer up to 750 kg.

  • Category C1: goods vehicles from 3,500 kg to 7,500 kg; Category C: goods vehicles over 3,500 kg (C1 included), optionally with a trailer up to 750 kg.

  • Category D1: buses with up to 16 passenger seats plus the driver and maximum length 8 m; Category D: buses with more than 8 seats, no upper mass limit.

  • Trailer classes: BE up to 3,500 kg trailer, C1E up to 7,500 kg combination, CE unlimited, DE buses with trailer.

  • A category C or D licence requires a medical certificate and, for professional use, a Certificate of Professional Competence (CPC).

  • Drivers under 21 cannot hold a C or D licence for hire or reward; minimum age for C is 21 and for D is 24, with exceptions for scheduled services under 50 km.

  • Category AM covers mopeds up to 50 cc and 45 km/h; A1 up to 125 cc and 11 kW; A2 up to 35 kW; A unlimited.

  • Licence categories are shown on the Greek licence with harmonised EU codes; code 95 marks CPC qualification.

Weights, Dimensions and Loads

  • EU maximum authorised mass for a rigid lorry is 40 t; a road train (lorry plus trailer) may reach 40 t, and 44 t for combined transport of containers.

  • Maximum width 2.55 m (2.60 m for refrigerated vehicles), maximum height 4.00 m, maximum length 12 m for a rigid vehicle and 18.75 m for a road train.

  • Maximum axle load is 10 t for a single driving axle and 11.5 t for a single non-driving axle; a tandem axle group is limited to 19 t.

  • Payload = maximum authorised mass minus kerb weight; the load must never push any axle over its plated limit, so distribute weight evenly.

  • Loads may overhang the front only slightly; rear overhang beyond the vehicle body must be marked with a red-and-white panel by day and a red light at night.

  • Loads projecting more than 1 m beyond the rear must be signalled; the total length including load must stay within legal limits.

  • The load must be secured so it cannot shift, fall, or drag; tarpaulins and ropes must be checked before departure and after the first 50 km.

  • Vehicle documents carried: registration certificate, insurance certificate, and for hire or reward the licence and CPC card; the tachograph record must be available for inspection.

Quick reference

Driver Hours, Rest Periods and Tachograph

  • Daily driving limit is 9 hours, extendable to 10 hours twice in a week; weekly driving limit is 56 hours; two consecutive weeks must not exceed 90 hours.

  • After 4.5 hours of driving a 45-minute break is required, which may be split into 15 minutes followed by 30 minutes.

  • Daily rest is 11 hours, reducible to 9 hours at most three times between weekly rests; a split daily rest is 3 hours plus 9 hours.

  • Weekly rest is 45 hours, reducible to 24 hours; any reduction must be compensated en bloc before the end of the third following week.

  • A rest period is uninterrupted time for recuperation; a break is any period not counted as driving or other work.

  • The tachograph records driving, other work, availability and rest; manual entries must be made for any period not recorded automatically.

  • Drivers must carry the previous 28 days of tachograph records and the current day's record and present them on request.

  • The digital tachograph card is personal; using another driver's card or driving without a card is an offence.

Quick reference

Vehicle Mechanics, Maintenance and Pre-Trip Checks

  • Daily walk-around check: tyres (tread depth at least 1.6 mm for cars, 1.0 mm for lorries, no cuts or bulges), lights, mirrors, plates, and load security.

  • Check engine oil, coolant and washer fluid with the engine cold and the vehicle level; low coolant can cause overheating and head gasket failure.

  • Air brake system: pressure must build to operating level before moving; a warning buzzer or low-pressure lamp means do not drive.

  • Drain water from the air tanks and check the automatic drain; moisture in the air system can freeze and disable the brakes in winter.

  • Tyre pressure is checked cold; under-inflation increases rolling resistance, fuel consumption and tyre temperature, risking a blowout.

  • Brake test: at low speed apply the brakes firmly and check for pull to one side, vibration, or a spongy pedal, indicating air or fluid loss.

  • The ABS warning lamp must go out after the self-test; if it stays on, the anti-lock function is disabled even if normal braking works.

  • Check the coupling and safety devices of a trailer: fifth-wheel jaw, kingpin, air lines, electrical cable, and the parking brake.

First Aid, Emergencies and Accident Procedure

  • At an accident: stop, secure the scene with hazard lights and warning triangle at least 50 m behind (150 m on motorways), and call 112.

  • Do not move an injured person unless there is fire, risk of further collision, or the airway is blocked; suspected spinal injury makes movement dangerous.

  • Check responsiveness and breathing; if absent, start chest compressions at 100-120 per minute, 5-6 cm deep, and use an AED if available.

  • For severe bleeding, apply direct pressure with a clean cloth and elevate the limb; do not remove an object embedded in a wound.

  • For burns, cool with running water for at least 10 minutes and never apply ice, butter, or ointments; do not burst blisters.

  • Place an unconscious but breathing casualty in the recovery position and monitor breathing continuously until help arrives.

  • A fire in the engine compartment: switch off the engine, do not open the bonnet fully, and use a dry powder or CO2 extinguisher through the gap.

  • Exchange details at the scene: names, addresses, insurance and registration numbers; report the accident to the police if there are injuries or a dispute.

Quick reference

Environmental Driving and Fuel Efficiency

  • Fuel consumption rises steeply above 80-90 km/h because aerodynamic drag increases with the square of speed; driving at 80 instead of 100 km/h saves roughly 20-25% fuel.

  • Use the highest gear that does not labour the engine; change up at about 1,500-2,000 rpm in a diesel and keep the engine in its economical band.

  • Anticipate traffic and use engine braking rather than late, hard braking; smooth driving cuts fuel use and brake wear.

  • Idling wastes about 0.5-1 litre per hour; switch off the engine for stops longer than about 30 seconds where the vehicle allows it.

  • Correct tyre pressure and wheel alignment reduce rolling resistance; under-inflated tyres can raise fuel consumption by several percent.

  • Remove unnecessary roof racks and empty loads; extra mass and drag increase consumption and emissions.

  • A cold engine uses more fuel; avoid short trips and combine errands, and do not warm up by idling.

  • Euro emission standards (Euro VI for new lorries) set NOx and particulate limits; low-emission zones may restrict older vehicles.

Quick reference

Professional Driver Conduct

  • The driver is responsible for the vehicle, the load and the tachograph records; falsifying records or tampering with the tachograph is an offence.

  • Professional drivers must hold a valid CPC card and complete 35 hours of periodic training every 5 years.

  • A driver must not drive under the influence of alcohol, drugs or fatigue; fatigue is a leading cause of lorry accidents, and the remedy is rest, not coffee.

  • Courteous behaviour includes not tailgating, giving way to buses leaving stops, and not blocking junctions or pedestrian crossings.

  • The driver must check the load and secure it before departure and is liable for overweight or unsecured loads even if loaded by others.

  • Report accidents and mechanical defects to the operator immediately; the operator must keep maintenance records for inspection.

  • Drivers must carry a valid driving licence, CPC card, medical certificate and vehicle documents and present them to inspectors.

  • Discrimination, harassment and aggressive driving are disciplinary matters; keep a professional log of incidents.

Quick reference

Passenger Safety and Documentation

  • Bus passengers must be seated or provided with handholds; standing passengers are not allowed on motorways or at speeds above 80 km/h.

  • Safety belts must be worn where fitted; the driver must ensure that children are properly restrained and that the aisle and exits are clear.

  • Emergency exits must be marked, unobstructed and operable from inside; the driver checks them before each trip.

  • A first-aid kit, fire extinguisher and warning triangle are mandatory equipment on buses; check their presence and expiry dates.

  • Before departure the driver checks the passenger list, luggage security, doors closed and the route; the bus must not move with a door open.

  • Passengers may not stand in the stairwell, on the platform, or lean out of windows; the driver enforces this and stops the vehicle if necessary.

  • Transport documents: the passenger transport licence, the vehicle registration, insurance for passengers, and the driver's CPC card must be on board.

  • For international or school transport, additional authorisation and a passenger list are required; keep them with the vehicle documents.

Quick reference

Traffic Law and Road Signs

  • A yellow diamond sign indicates a priority road; at its end the priority-to-the-right rule resumes.

  • Traffic lights: flashing amber means proceed with caution and give way as at an uncontrolled junction.

  • A solid white line means no crossing; a broken line may be crossed when safe.

  • Overtaking is prohibited at pedestrian crossings, on bridges, in tunnels and where visibility is limited.

  • Parking is prohibited within 5 m of a junction, on crossings, at bus stops and on pavements unless signed.

  • A vehicle must stop for a red light before the stop line, not on the crossing.

  • Roundabouts: traffic already on the roundabout has priority unless signs say otherwise.

Quick reference

Road Safety and Hazard Perception

  • In strong crosswind, reduce speed and hold the wheel firmly; high-sided vehicles are most affected on bridges and open stretches.

  • At night, dip headlights when meeting oncoming traffic and when following another vehicle.

  • When a vehicle ahead flashes its headlights, do not assume it is giving way; check the situation yourself.

  • Tiredness signs: heavy eyelids, wandering attention, yawning; stop at a safe place and rest.

  • Snow chains are required where signed; fit them on the driving wheels and keep speed below 50 km/h.

  • A skid is corrected by steering into it and easing off the accelerator, not by braking hard.

Quick reference

Vehicle Categories

  • A BE licence allows a category B vehicle with a trailer over 750 kg, up to a combined mass of 3,500 kg.

  • A C1E licence allows a C1 vehicle with a trailer over 750 kg, up to a combined mass of 12,000 kg.

  • A D1E licence allows a D1 bus with a trailer over 750 kg, up to a combined mass of 12,000 kg.

  • A CE licence covers a C vehicle with a trailer of any mass.

  • A DE licence covers a D bus with a trailer of any mass.

  • Codes on the licence (e.g. 95, 01, 78) restrict or describe the entitlement; 95 means CPC qualification.

Quick reference

Weights, Dimensions and Loads

  • The plated maximum authorised mass is shown on the manufacturer's plate; it must not be exceeded even if the road limit is higher.

  • The axle load limit is checked on a weighbridge; overloading an axle damages the road and causes tyre failure.

  • A load must not obstruct lights, plates, mirrors or the driver's view.

  • Loads that can shift must be restrained with straps, nets or bars rated for the load.

  • The load must be covered if it can blow off or cause dust.

  • Maximum height including load is 4.00 m; check bridge heights on the route.

Quick reference

Driver Hours, Rest Periods and Tachograph

  • Driving time includes time spent at the wheel with the vehicle moving; waiting time with the engine off can be recorded as availability.

  • A break may be taken on the vehicle if the driver is not required to work.

  • The tachograph must be switched to the correct mode: driving, other work, availability, rest.

  • Records must be produced for the last 28 days; missing records can lead to a fine.

  • The weekly rest must be taken in the first 24 hours after the end of the previous weekly rest.

  • Compensation for reduced weekly rest is added to a rest period of at least 9 hours.

Quick reference

Vehicle Mechanics, Maintenance and Pre-Trip Checks

  • Check the battery terminals and electrolyte level; a weak battery fails in cold weather.

  • Check the alternator belt tension and condition; a slipping belt stops charging.

  • Check the cooling fan and radiator for debris; a blocked radiator causes overheating.

  • Check the exhaust for leaks; carbon monoxide can enter the cab.

  • Check the lights and indicators with a helper or by reflection.

  • Check the mirrors and adjust them before moving.

  • Check the fire extinguisher pressure gauge and the first-aid kit.

Quick reference

First Aid, Emergencies and Accident Procedure

  • Call 112 for ambulance, police or fire; give location, number of casualties and hazards.

  • Do not give food or drink to an injured person.

  • Keep the casualty warm with a blanket or coat.

  • For a fracture, immobilise the limb and do not attempt to straighten it.

  • For a suspected spinal injury, keep the head and neck still and wait for help.

  • For a choking casualty, give back blows and abdominal thrusts.

  • For a chemical splash in the eye, rinse with clean water for at least 15 minutes.

Quick reference

Environmental Driving and Fuel Efficiency

  • Plan routes to avoid congestion and steep gradients; a steady route saves fuel.

  • Use cruise control on motorways where traffic allows.

  • Avoid rapid acceleration and late braking; smooth driving cuts fuel use.

  • Keep the engine well maintained; a dirty air filter or faulty injector increases consumption.

  • Use the correct engine oil grade; the wrong oil increases friction.

  • Check the tyre pressure weekly; under-inflation raises consumption.

  • Do not carry unnecessary weight; every 100 kg adds about 1% fuel use.

Quick reference

Professional Driver Conduct

  • Keep a professional appearance and treat passengers and other road users with respect.

  • Do not use a mobile phone while driving; use hands-free only.

  • Do not smoke in the cab if the vehicle is a bus or carries passengers.

  • Report any accident, near miss or defect to the operator.

  • Keep the cab clean and the documents in order.

  • Do not accept gifts or favours that could affect your judgement.

  • Follow the operator's instructions on routes and schedules.

Quick reference

Passenger Safety and Documentation

  • Check the passenger list before departure and after each stop.

  • Ensure luggage is stored safely and does not block the aisle or exits.

  • Check that doors are closed before moving.

  • Ensure the first-aid kit and fire extinguisher are on board and in date.

  • Know the location of emergency exits and how to open them.

  • Keep the transport licence, insurance and CPC card on board.

  • For school transport, keep the passenger list and authorisation with the documents.
