CBR Bus Theory D common mistakes
CBR Bus Theory D · Understand the traps and how to avoid them.
On priority questions the candidate stops answering at 'who goes first' and forgets that a bus pulling out of a stop inside a built-up area must be given free passage by other traffic, so they mark the car as having priority.
Candidates learn the general right-hand rule and the sign hierarchy, but do not connect the special bus provision to it, because it appears in a different article of the RVV 1990 than the priority rules they revise.
What to do instead
Drill the bus-specific exceptions as a separate list: free passage for a bus leaving a stop within the built-up area, and the tram/bus priority order at unsignalised junctions. For each exception, write out who must yield and to whom, then test yourself on mixed scenarios where the bus is the one emerging.
The candidate treats a 'closed for all traffic' sign as identical to a 'closed for motor vehicles' sign and answers that a bus may pass a sign that in fact excludes it too.
The C-round prohibition signs look similar and candidates memorise the shape (red circle) rather than the pictogram inside, and buses fall under different categories (motor vehicle, goods vehicle above a mass limit) depending on the sign.
What to do instead
Build a one-page table of every C-sign with its exact scope: pedestrians, bicycles, motor vehicles, goods vehicles over a stated mass, vehicles over a stated length or width. Add the onderborden (exception plates) that exempt buses or line buses, and rehearse the table until you can state the scope from the pictogram alone.
The candidate reads a speed-limit question as 'what is the maximum here' and answers 80 km/h on a road outside the built-up area, ignoring that a bus is limited to a lower figure and that the lower limit applies even where a higher sign is posted.
Candidates revise the general limits for cars and assume the same figures apply to the bus they will drive, and they do not distinguish the limit for the vehicle category from the limit shown on the sign.
What to do instead
Memorise the bus-specific maximum as a separate number and practise questions where a sign shows a higher limit than the bus limit, so the answer is always the lower of the two. State the rule aloud each time: the vehicle limit applies regardless of the posted sign when it is lower.
The candidate answers tachograph questions by counting only driving time and ignores other work, availability and breaks, so a 45-minute break taken as 3×15 minutes is accepted as valid.
The 15+30 split is well known, but candidates do not internalise that the second part must be at least 30 minutes and that the split must be taken in that order; they also forget that loading, paperwork and vehicle checks count as other work and eat into the 13-hour duty window.
What to do instead
Work through a full 24-hour timeline for a realistic bus day, marking each activity as driving, other work, availability or break, and check the totals against the daily driving limit, the 9-hour daily rest reduction and the weekly totals. Redo the timeline with the 15+30 split in the wrong order to see why it fails.
The candidate applies the 4.5-hour driving rule to a regular national bus service and marks the tachograph as required, when the vehicle falls under a national exemption from EU Regulation 561/2006.
Training material presents the EU regulation as universal and candidates do not learn the exemption list, nor that a national rule may still require recording even when the EU regulation does not apply.
What to do instead
Learn the exemption categories by name (regular services on routes not exceeding 50 km, certain vehicles used by public authorities, and the others in the regulation) and, for each, state whether a tachograph, a national record or nothing is required. Then answer mixed questions where the only clue is the route length or the type of service.
When a passenger stands up before the bus has stopped, the candidate brakes hard to 'teach' the passenger or simply continues, instead of choosing the graded response the exam expects.
Candidates answer from instinct about everyday bus driving rather than from the defensive-driving principle that an unsecured passenger is a hazard to be managed smoothly, and they forget that harsh braking is itself a cause of passenger injury.
What to do instead
Learn the graded response: reduce speed early, brake progressively, avoid sudden steering, and only stop fully if the passenger remains standing or moves toward the doors. Practise describing the sequence in order, because exam questions often ask for the first action rather than the best overall action.
The candidate answers a mirror and blind-spot question by naming the mirror to check but omits the shoulder check and the front blind spot, and treats the interior mirror as sufficient for the nearside.
Candidates transfer car habits to the bus, where the flat interior mirror shows little of the nearside and the front blind spot in front of the windscreen is large; they also underestimate how far the nearside mirror overstates distance.
What to do instead
Memorise the bus blind-spot zones as a diagram you can draw from memory: directly in front of the bumper, the nearside flank at the front door, and the area behind the rear axle. For each manoeuvre, state the order: mirrors, shoulder check, signal, move, and repeat the nearside check before turning across a cycle lane.
The candidate loads a coach for a school trip and answers that the luggage may go in the aisle or on the rear platform if the boot is full, and does not check the permitted axle loads.
Candidates focus on the total permissible mass and forget that the axle loads and the load distribution matter, and they do not know that an obstructed aisle or emergency exit is a prohibition, not a preference.
What to do instead
Learn the three checks in order: total mass against the permissible maximum, each axle against its permitted load, and the load secured so that no item can move and no exit or aisle is blocked. Practise questions where the boot is full and the correct answer is to leave items behind or arrange a second vehicle.
On a first-aid question the candidate says to move an injured motorcyclist out of the road immediately, or to give an unconscious casualty a drink, instead of securing the scene and checking breathing.
Candidates prioritise clearing traffic over casualty care and do not know the order of the emergency protocol, nor that moving a casualty can worsen spinal injury unless there is an immediate danger such as fire.
What to do instead
Learn the fixed sequence: warn traffic and put on the hazard lights and warning triangle, check danger to yourself, check consciousness and breathing, call the emergency number with the location and number of casualties, and only then give care. Rehearse the sequence for a bus incident where the priority is evacuating passengers from the vehicle before treating them.
The candidate evacuates passengers through the nearest door in every emergency, including a fire in the engine compartment at the rear, and does not consider which exits are usable and which passengers need help first.
Candidates answer evacuation questions as a single routine and do not learn that the exit choice depends on the location of the hazard, nor that the emergency door, roof hatch and windows are alternative exits whose operation they must be able to describe.
What to do instead
For each hazard type (fire at the front, fire at the rear, collision blocking a door, vehicle in water), state which exits are used, in what order passengers leave, and who assists passengers with reduced mobility. Learn the operation of the emergency door release and the roof hatch, including that the engine must be switched off and the handbrake applied before evacuation.
