Bulgaria Driver CPC common mistakes
Bulgaria Driver CPC · Understand the traps and how to avoid them.
Treating the posted speed limit as the target speed and braking late into bends or hazards instead of adjusting speed before the hazard and using engine braking plus progressive braking.
Candidates memorise limits as compliance numbers and underestimate how a laden vehicle's mass and high centre of gravity lengthen stopping distance and shift weight forward under braking.
What to do instead
Practise a fixed routine: identify the hazard, reduce speed before it using engine braking and gentle continuous braking, keep both hands on the wheel, and only then steer. Justify each speed choice aloud by reference to load, road surface, visibility and gradient.
Descending long gradients in a high gear with the service brake held continuously, or coasting in neutral to save fuel.
Fuel-economy advice about coasting is misapplied to descents, and candidates fear over-revving the engine, so they rely on the footbrake until it fades.
What to do instead
Select a gear that holds a safe speed without gaining revs, use the retarder or exhaust brake where fitted, and apply the service brake only in short firm applications. State explicitly that coasting and neutral are prohibited because they remove engine braking and vehicle control.
Misreading the tachograph mode switch, leaving the unit on 'other work' during loading or on 'driving' while stationary, and failing to make manual entries for work done away from the vehicle.
The four-mode switch is confused under time pressure, and candidates do not realise that manual entries and printouts are part of the assessed competence, not optional housekeeping.
What to do instead
Learn the mode sequence and when each applies, rehearse making manual entries on a training unit, and always carry enough printout paper. Before any check, confirm mode, record any missing activity, and be able to explain each entry on a printout.
Planning daily driving time to the absolute limit with no margin, then exceeding 4.5 hours of driving or taking a break of only 40 minutes instead of the required 45.
Candidates calculate against ideal traffic and assume breaks can be split arbitrarily, forgetting that a split break must be 15 minutes followed by 30 minutes in that order.
What to do instead
Plan with a buffer, schedule the first break at about 15 minutes and the second at 30 minutes in the correct order, and use a written plan showing driving, break, rest and availability periods before departure.
Failing the daily walk-round check because the candidate only looks at tyres and lights, skipping load security, coupling security on articulated units, fluid levels, warning lamps and the condition of the tachograph seal.
The check is treated as a ritual to be recited rather than a systematic inspection, and candidates have not internalised a fixed sequence.
What to do instead
Use a fixed clockwise sequence from the front of the vehicle around the combination and back, naming each item and its acceptance criterion, including coupling locks, load restraints, tyre tread and pressures, lamps, fluids and dashboard warnings. Record defects and state the procedure for reporting them.
Underestimating the blind spots and swept path of a long combination, swinging wide into the opposing lane on right turns and cutting the corner on left turns.
Candidates drive the vehicle as if it were a car and do not visualise the rear axle path or the area hidden by the mirrors and cab pillars.
What to do instead
Before every turn, check both mirrors and the blind-spot area, take the correct position, and use the 'go wide, come back' technique for right turns. Practise judging the swept path with cones and state the mirror check order aloud.
Giving a single mirror glance before a lane change or manoeuvre instead of a structured observation cycle including blind spots and, where fitted, camera or sensor systems.
Mirror use is habitual and shallow, and candidates assume that a mirror showing no vehicle means the space is clear.
What to do instead
Adopt a repeatable observation sequence: mirrors, blind spot, signal, mirrors again, manoeuvre. Emphasise that mirrors have blind spots and that camera and sensor aids supplement, never replace, direct observation.
Loading the vehicle without checking axle load distribution, exceeding the permitted gross or axle weight, or relying on the load's own weight to keep it in place.
Candidates think only about total payload and forget individual axle limits, load-bearing capacity of the restraint system, and the effect of a high centre of gravity on stability.
What to do instead
Calculate gross and axle loads before departure, place heavy items low and over the drive axles, and secure the load with a restraint system whose capacity matches the load. Be able to state the consequences of overload for braking, steering and legality.
Skipping or rushing the pre-journey check of the digital tachograph and the vehicle's safety systems, including warning lamps that stay illuminated after start-up.
Candidates treat warning lamps as noise and assume the tachograph is the workshop's responsibility, so they never verify card insertion, correct time and functioning of the unit.
What to do instead
Build a start-up checklist: insert the driver card, verify the displayed time and mode, note any warning lamp and its meaning, and confirm the tachograph is functioning. Know which faults require the vehicle to be stopped and reported rather than driven.
Ignoring the effect of fatigue, medication and shift timing on driving, and treating the health and fitness rules as paperwork rather than a live operational constraint.
Candidates separate 'health' from 'driving' and do not connect sleep debt, circadian low points, alcohol clearance times or prescribed medicines to real impairment.
What to do instead
Learn the signs of fatigue and the countermeasures that work (planned rest, short naps, avoiding the early-morning low point) versus those that do not (fresh air, loud music, caffeine as a substitute for sleep). Be able to state the employer's and driver's responsibilities for fitness to drive and for reporting medical conditions.
