Question 1Incident Environment

A coach breaks down on a high-speed road shoulder. What is the best first priority?

  1. Protect passengers and the scene: stop safely, use hazard warning, move passengers away from danger when safe, and warn traffic Correct answer.
  2. Keep passengers seated next to fast traffic for comfort
  3. Try to repair the bus in the live lane
  4. Turn off all lights to save battery

Explanation

A breakdown becomes an emergency scene when a large passenger vehicle is near moving traffic. The driver should secure the vehicle, make it visible, protect passengers, and call for help as needed.

Question 2Finnish Framework

What vehicle type is Finland Category D primarily for?

  1. Motorcycles over 35 kW
  2. Buses and coaches Correct answer.
  3. Passenger cars with trailers
  4. Goods vehicles over 3,500 kg

Explanation

Traficom describes Category D as the licence needed to drive a bus or coach. Category C is for lorries, while Category B is for passenger cars and vans within its limits.

Question 3Finnish Framework

Which statement best describes a Category D1 bus in Finland?

  1. It may carry no more than eight passengers
  2. It may carry up to 16 passengers and must not exceed 8 metres in length Correct answer.
  3. It is any bus with a trailer over 750 kg
  4. It is only for electric city buses

Explanation

Traficom lists Category D1 for smaller buses designed for a maximum of 16 passengers in addition to the driver, with a vehicle length not exceeding 8 metres. Category D covers larger bus and coach vehicles.

Question 4Finnish Framework

With a Finnish Category D bus licence, what trailer limit applies without a DE category?

  1. A trailer up to 750 kg Correct answer.
  2. A trailer up to 1,250 kg
  3. Any trailer if it is empty
  4. No trailer of any weight may be towed

Explanation

Traficom states that Category D allows a Category D towing vehicle with a towed vehicle not exceeding 750 kg. A heavier trailer requires the DE combination category.

Question 5Finnish Framework

Which licence category is needed for a Category D bus with a trailer over 750 kg?

  1. D1
  2. D
  3. DE Correct answer.
  4. B/96

Explanation

Traficom lists DE as the category for vehicle combinations with a Category D towing vehicle and a trailer over 750 kg. Category D by itself is limited to a trailer that does not exceed 750 kg.

Question 6Finnish Framework

What extra qualification is required for bus and coach drivers working in commercial transport?

  1. Professional competence of a bus and coach driver Correct answer.
  2. A motorcycle instructor certificate
  3. A private security guard card
  4. A recreational boating certificate

Explanation

Traficom states that all bus and coach drivers working in commercial transport must also have valid professional competence. A Category D licence gives driving entitlement, but commercial passenger transport adds professional qualification duties.

Question 7Finnish Framework

What are Finnish theory-test questions based on according to Ajovarma?

  1. Road traffic and vehicle legislation, related regulations, and general road-traffic principles Correct answer.
  2. Only local bus-company route manuals
  3. Only the candidate's driving-school marketing material
  4. Only questions about vehicle insurance pricing

Explanation

Ajovarma describes the questions as based on road traffic and vehicle legislation, regulations issued under them, and the general principles of road traffic. That is why practice should cover rules, signs, hazards, vehicle operation, and responsible driving.

Question 8Finnish Framework

Which vehicle fits Category D rather than Category B based on passenger capacity?

  1. A car designed for eight passengers plus the driver
  2. A van designed for seven passengers plus the driver
  3. A vehicle designed for more than eight passengers in addition to the driver Correct answer.
  4. A two-wheeled motorcycle with one passenger seat

Explanation

Traficom states that Category D covers vehicles designed and manufactured to carry more than eight passengers in addition to the driver. Category B is limited to vehicles designed for a maximum of eight passengers in addition to the driver.

Question 9Finnish Framework

Why does a Category B licence not by itself authorize driving a full-size coach?

  1. Category B vehicles are limited to a maximum of eight passengers in addition to the driver Correct answer.
  2. Category B is valid only for mopeds
  3. Category B allows only vehicles with manual transmission
  4. Category B is valid only inside Finland during daylight

Explanation

Traficom describes Category B as cars up to 3,500 kg designed for a maximum of eight passengers in addition to the driver. A full-size coach is designed for more passengers and requires the bus category.

Question 10Finnish Framework

A vehicle is designed for 16 passengers plus the driver and is 7.8 metres long. Which bus category does Traficom describe for this size?

  1. D1 Correct answer.
  2. D only
  3. C1
  4. AM/121

Explanation

D1 covers buses designed for a maximum of 16 passengers in addition to the driver and no more than 8 metres long. Category D covers larger buses, but D1 is the smaller bus category for this exact limit.

Question 11Finnish Framework

A Category D coach will tow a trailer with an allowed mass over 750 kg. What is the licensing issue?

  1. A Category D licence alone is enough for any trailer
  2. The driver needs the DE combination category Correct answer.
  3. The trailer can be ignored if no passengers are aboard
  4. The driver needs only a Category BE licence

Explanation

Category D permits a trailer only up to 750 kg. A heavier trailer behind a Category D bus requires Category DE, regardless of whether passengers are aboard.

Question 12Finnish Framework

Which statement best separates a Category D licence from commercial bus-driver professional competence?

  1. The Category D licence is driving entitlement; commercial passenger work also requires valid professional competence Correct answer.
  2. Professional competence replaces the need for a Category D licence
  3. A Category D licence automatically proves all professional competence forever
  4. Neither is needed on scheduled routes

Explanation

Traficom identifies the bus licence process separately from the professional competence required for commercial transport. A commercial bus driver must hold both the appropriate right to drive and the required professional competence.

Question 13Finnish Framework

What training content does Traficom require in professional competence training for lorry and bus drivers?

  1. Safe, economical, and environmentally friendly driving plus risk recognition and accident response Correct answer.
  2. Only route memorisation for the driver's home city
  3. Only ticket-machine operation
  4. Only washing and refuelling the vehicle

Explanation

Traficom describes professional competence training as including safe, economical, and environmentally friendly driving, risk-factor recognition, avoiding dangerous situations, and acting in accidents. These topics overlap with the hazard and responsibility focus of the Category D theory test.

Question 14Finnish Framework

A driver has a Category D licence but no valid bus-driver professional competence. What is the safest exam answer for commercial passenger transport?

  1. They may drive commercial passengers because the licence alone is enough
  2. They need valid professional competence before working in commercial bus or coach transport Correct answer.
  3. They may work only if passengers sign a waiver
  4. They may work only at night

Explanation

Traficom states that bus and coach drivers working in commercial transport must have valid professional competence. Passenger waivers or time of day do not remove that qualification duty.

Question 15Finnish Framework

For road passenger transport, when is a tachograph required under Traficom guidance?

  1. For vehicles designed for more than 9 persons including the driver, subject to exceptions Correct answer.
  2. Only for motorcycles used commercially
  3. Only for empty buses in private yards
  4. Only when the bus is painted in a public-transport colour

Explanation

Traficom states that tachographs are mandatory in road passenger transport for vehicles manufactured to carry more than 9 people including the driver, subject to listed exceptions. Most commercial bus and coach operations therefore require tachograph use.

Question 16Finnish Framework

What is a main purpose of tachograph rules in bus transport?

  1. Improving traffic safety, monitoring social-legislation compliance, and protecting working conditions Correct answer.
  2. Making the bus accelerate faster
  3. Replacing the driver's licence
  4. Allowing drivers to skip rest periods when late

Explanation

Traficom explains that the tachograph supports compliance with road-transport social legislation, traffic safety, fair competition, and driver working conditions. It is a safety and compliance tool, not a performance upgrade.

Question 17Finnish Framework

What does Traficom say a second-generation smart tachograph can automatically record?

  1. Location data, border crossings, and loading or unloading events Correct answer.
  2. Passenger opinions about the route
  3. The driver's eyesight test results
  4. Only the bus radio station

Explanation

Traficom describes the second-generation smart tachograph as improving data security and automatically recording items such as location data, border crossings, and loading or unloading events. In bus work, it is part of modern compliance duties.

Question 18Finnish Framework

Which tachograph card should a professional bus driver use for their own driving activity?

  1. Their personal driver card Correct answer.
  2. The company card as a personal substitute
  3. A workshop card borrowed from a repair shop
  4. A control card issued for enforcement

Explanation

The driver card is personal and intended to record that driver's driving and rest activity. Other card types have different roles and are not substitutes for the driver's personal record card.

Question 19Finnish Framework

Under the standard EU driving-time rule, what break is required after 4.5 hours of driving if no rest period begins?

  1. At least 15 minutes total
  2. At least 30 minutes total
  3. At least 45 minutes total Correct answer.
  4. No break if passengers remain seated

Explanation

EU driving-time rules require a break of at least 45 minutes after 4.5 hours of driving unless the driver starts a rest period. Passenger presence does not remove the break requirement.

Question 20Finnish Framework

What is the usual maximum daily driving time under EU driving-time rules, with limited extensions?

  1. 7 hours, never extendable
  2. 9 hours, extendable to 10 hours twice in a week Correct answer.
  3. 12 hours every day
  4. No maximum if the tachograph is working

Explanation

EU rules set daily driving time at 9 hours, with extension to 10 hours no more than twice during a week. A working tachograph records compliance; it does not remove the limit.

Question 21Finnish Framework

Which pair matches the EU weekly and two-week driving-time limits?

  1. 40 hours weekly and 80 hours in two weeks
  2. 45 hours weekly and 100 hours in two weeks
  3. 56 hours weekly and 90 hours in two weeks Correct answer.
  4. 70 hours weekly and 140 hours in two weeks

Explanation

EU rules limit weekly driving time to 56 hours and total driving time over two consecutive weeks to 90 hours. Bus scheduling must be built around these limits, not around timetable pressure alone.

Question 22Finnish Framework

A coach is behind schedule and the tachograph shows the driver is nearing the 4.5-hour driving limit. What is the professional response?

  1. Continue until the destination because passengers dislike delays
  2. Plan and take the required break or rest, informing the operator as needed Correct answer.
  3. Remove the driver card to stop recording
  4. Ask a passenger to drive for ten minutes

Explanation

Driving-time and rest rules exist to prevent fatigue-related crashes. A professional driver must plan lawful breaks and communicate operational delays rather than hiding or ignoring the limit.

Question 23Finnish Framework

A coach is designed for 48 passengers plus the driver and tows a trailer with an allowed mass of 800 kg. Which category issue is present?

  1. Category D alone is enough because the trailer is under 1,000 kg
  2. DE is needed because the trailer is over 750 kg behind a Category D vehicle Correct answer.
  3. D1E is enough because any trailer makes the bus D1
  4. Only Category B is needed if the trailer is empty

Explanation

Category D covers the bus but only allows a trailer not exceeding 750 kg. An 800 kg trailer behind a Category D coach points to the DE combination category.

Question 24Finnish Framework

A dispatch message asks the coach driver to skip a required break to protect a tour schedule. What should the driver do?

  1. Follow legal driving-time and rest requirements and notify operations of the delay Correct answer.
  2. Skip the break if passengers agree
  3. Drive with the card removed
  4. Record the break while continuing to drive

Explanation

Driving and rest rules are safety duties and cannot be waived by schedule pressure or passenger preference. The driver must keep records accurate and communicate operational consequences lawfully.

Question 25Finnish Framework

For an occasional bus service where the 2024 flexibility applies, how may the 45-minute break for 4.5 hours of driving be split under Traficom's notice?

  1. Into two breaks of at least 15 minutes each Correct answer.
  2. Into five breaks of 5 minutes each
  3. Into any number of 1-minute stops
  4. It may be cancelled completely

Explanation

Traficom's 2024 notice for national and international occasional bus services states that the 45-minute minimum break for 4.5 hours of driving can alternatively be taken as two breaks of at least 15 minutes each, when the conditions apply. The flexibility changes how the break can be arranged; it does not cancel the break.

Question 26Finnish Framework

From 31 December 2024, what period of journey-form copies does Traficom say may be needed in the vehicle to prove occasional bus-service flexibilities?

  1. The preceding 7 days
  2. The preceding 28 days only
  3. The preceding 56 days Correct answer.
  4. No copies are needed if the driver remembers the route

Explanation

Traficom's notice says the proof for occasional-service flexibilities can involve keeping completed journey forms and copies in the vehicle, covering the preceding 28 days and from 31 December 2024 the preceding 56 days. Documentation matters because enforcement may check compliance later.

Question 27Priority Signs

What does Traficom say bus and coach instruction teaches about dangerous traffic situations?

  1. Ignore them if the timetable is late
  2. Identify and avoid them through anticipation Correct answer.
  3. Leave them for passengers to manage
  4. Handle them only during the final driving test

Explanation

Traficom describes anticipation as learning to identify and avoid dangerous situations in traffic. This is central to the theory test because it includes hazard-recognition questions.

Question 28Priority Signs

When approaching a pedestrian crossing, what is the safe legal approach for a bus driver?

  1. Maintain speed unless a pedestrian is already in front of the bus
  2. Drive at a speed that allows stopping before the crossing if needed Correct answer.
  3. Sound the horn and keep moving
  4. Use the bus size to make pedestrians wait

Explanation

The Road Traffic Act requires special caution near pedestrian crossings and a speed low enough to stop before the crossing if necessary. This is especially important in a bus because stopping distance and blind areas are larger than in a car.

Question 29Priority Signs

On a road with a speed limit of 60 km/h or less, what happens when a bus at a stop signals that it intends to move off?

  1. Approaching vehicles on the same or adjacent lane must yield to the bus Correct answer.
  2. The bus may move without checking mirrors
  3. Only cyclists must yield
  4. The rule applies only on motorways

Explanation

The Finnish Road Traffic Act gives a bus leaving a stop this special protection on roads where the maximum speed is 60 km/h or less. The bus driver still has to signal clearly and move off safely.

Question 30Priority Signs

What should a bus driver do when an emergency vehicle approaches using warning signals?

  1. Compete for the lane to stay on schedule
  2. Give clear passage and avoid blocking it Correct answer.
  3. Stop in the middle of an intersection
  4. Follow closely behind the emergency vehicle

Explanation

Finnish road rules require road users to give clear passage to emergency vehicles and similar priority traffic. A bus driver should plan a controlled, visible movement that opens space without creating a new hazard.

Question 31Priority Signs

On a snowy Finnish road, what adjustment is most important for a bus driver?

  1. Increase following distance and use smooth steering, braking, and acceleration Correct answer.
  2. Drive closer to get better tyre heat
  3. Brake sharply to test grip with passengers aboard
  4. Rely on ABS to maintain summer stopping distances

Explanation

Low friction increases stopping distance and makes abrupt inputs more dangerous. A bus driver should slow early, leave more space, and use smooth controls so passengers and other road users remain safe.

Question 32Priority Signs

In a road tunnel, which bus-driving behaviour is safest?

  1. Keep a safe distance, obey signals, and be ready to stop or evacuate if directed Correct answer.
  2. Stop anywhere to take photos
  3. Drive close to the vehicle ahead to avoid gaps
  4. Ignore lane-control signals because buses are public transport

Explanation

Tunnel incidents can escalate quickly because space, visibility, and escape routes are limited. A bus driver should maintain distance, follow tunnel signs and signals, and know how to protect passengers if traffic stops.

Question 33Priority Signs

What should a bus driver do before entering a railway level crossing?

  1. Ensure there is enough space to clear the crossing completely Correct answer.
  2. Enter if the front half of the bus can fit
  3. Stop on the tracks to check the timetable
  4. Follow the vehicle ahead even if traffic is queued beyond the tracks

Explanation

A bus must never be trapped on a level crossing. The driver should enter only when the exit is clear enough for the whole vehicle to leave the crossing safely.

Question 34Priority Signs

What does using a direction indicator before a lane change mean for a bus driver?

  1. It communicates intention but does not by itself give priority Correct answer.
  2. It gives absolute priority over every vehicle
  3. It allows the driver to ignore mirrors
  4. It cancels the safe-distance rule

Explanation

Signals make intentions visible, but a lane change must still be safe. The driver must check mirrors, blind areas, traffic speed, and available space before moving a large vehicle sideways.

Question 35Priority Signs

When driving a bus in a lane marked and signed for bus use, what should the driver still do?

  1. Follow the signs, signals, markings, and any permitted-user restrictions for that lane Correct answer.
  2. Assume the lane is always free of taxis, bicycles, or turning traffic
  3. Drive above the posted speed limit because it is a bus lane
  4. Ignore traffic lights at the end of the lane

Explanation

Bus lanes are controlled by signs and markings that define who may use them and how. A bus driver must still obey speed limits, signals, crossings, and conflicts with other permitted users.

Question 36Priority Signs

A separate public-transport signal controls buses at an intersection. How should the bus driver treat it?

  1. As the applicable signal for the bus movement when it is provided for that traffic Correct answer.
  2. As decoration only
  3. As permission to ignore pedestrians
  4. As applying only to motorcycles

Explanation

Finnish road rules allow separate public-transport signals where bus or tram traffic is regulated separately from other traffic. The driver must obey the signal that applies to the bus movement and still watch for conflicts.

Question 37Priority Signs

Why must other vehicles avoid parking in a signed bus stop area?

  1. They can block boarding, alighting, and the bus path at a place reserved for bus service Correct answer.
  2. Because only police cars may ever stop there
  3. Because buses are forbidden to use marked stops
  4. Because passengers may board only from the road centreline

Explanation

The Road Traffic Act describes the bus-stop sign as indicating a place intended for boarding and alighting buses, with parking restrictions for other vehicles. Keeping the stop clear protects passenger access and safe bus positioning.

Question 38Priority Signs

A pedestrian is near a crossing partly hidden by a parked van. What should the bus driver do?

  1. Slow enough to stop before the crossing if the pedestrian steps out Correct answer.
  2. Maintain speed because the pedestrian is not fully visible
  3. Move left and pass without reducing speed
  4. Flash headlights to claim priority

Explanation

Finnish pedestrian-crossing rules require special caution and a speed that allows stopping if necessary. An obstruction makes the hazard worse, so a bus driver must slow and prepare to stop.

Question 39Priority Signs

How should a bus driver treat driver-assistance systems such as lane warnings or stability control?

  1. As aids that support, but do not replace, the driver's observation and judgement Correct answer.
  2. As permission to look away from the road
  3. As systems that remove all rollover risk
  4. As substitutes for professional competence

Explanation

Assistance systems can help, but the driver remains responsible for observation, speed choice, spacing, and passenger safety. Technology cannot overcome poor judgement or unsuitable speed.

Question 40Priority Signs

A bus at a stop on a 70 km/h road signals to move off. Which statement is most accurate?

  1. The special Finnish bus-stop yielding rule for roads up to 60 km/h does not require approaching vehicles to yield here Correct answer.
  2. Approaching vehicles must always yield at any speed limit
  3. The bus may pull out without checking because it signalled
  4. The bus must reverse before entering traffic

Explanation

The Road Traffic Act's special rule applies where the maximum permitted speed is 60 km/h or lower. On a 70 km/h road, the bus driver must rely on normal safe-entry and yielding rules and move only when safe.

Question 41Priority Signs

A bus is stopped at a bus stop on a 50 km/h road but has not signalled to move off. What should the driver understand about the special yielding rule?

  1. The special rule is triggered when the bus indicates its intention to start from the stop Correct answer.
  2. It applies even if the bus gives no signal and stays parked
  3. It gives the bus priority to reverse into traffic
  4. It applies only after the bus reaches 50 km/h

Explanation

The Finnish rule refers to a bus at a stop indicating by direction signal that it intends to start. Clear signalling and a safe movement are therefore part of the driver's responsibility.

Question 42Priority Signs

A bus stop is next to a cycle lane, and a motor vehicle approaches in the lane beside that cycle lane on a 50 km/h road. The bus signals to leave the stop. What does Finnish law require?

  1. The approaching motor vehicle must yield to the bus leaving the stop Correct answer.
  2. Only cyclists must yield; the adjacent motor lane never yields
  3. The bus must wait until every lane in the city is empty
  4. The rule applies only if the bus is empty

Explanation

The Road Traffic Act covers the case where the lane next to the stop is a cycle lane and extends the yielding duty to a vehicle approaching in the lane beside that cycle lane. The bus driver still must make a safe, signalled movement.

Question 43Priority Signs

A cyclist is riding along the right side of the bus as the driver prepares to turn right. What is the safest answer?

  1. Hold back and let the cyclist clear or establish clear eye contact and space before turning Correct answer.
  2. Turn immediately because the bus is ahead
  3. Move closer to the kerb to squeeze the cyclist out
  4. Use the indicator as a command for the cyclist to stop

Explanation

Right-turn side conflicts are among the most serious bus hazards because the cyclist can be hidden or trapped by the bus's swept path. The driver must not start the turn until the side is clear and the manoeuvre can be completed safely.

Question 44Bus Passengers

Before a right turn in a bus, what is especially important because of blind spots and swept path?

  1. Checking mirrors and blind areas for pedestrians, cyclists, and other vulnerable users Correct answer.
  2. Moving right as late and sharply as possible
  3. Looking only at the traffic light
  4. Ignoring the rear of the bus because only the front turns

Explanation

A bus has large blind areas and a wide swept path. The driver must check mirrors, blind spots, and the full side of the vehicle before and during the turn.

Question 45Bus Passengers

What is the best routine before moving off from a bus stop?

  1. Close doors, check mirrors and blind spots, signal clearly, and move only when safe Correct answer.
  2. Signal and move immediately because buses always have priority
  3. Ask passengers to watch traffic for the driver
  4. Reverse first to create more room

Explanation

A bus driver should confirm passengers and doors are clear, check mirrors and blind spots, signal, and move off smoothly. The bus-stop priority rule does not permit moving into danger.

Question 46Bus Passengers

What does a digital tachograph record for professional road transport?

  1. Driving and rest times, speed, and distance Correct answer.
  2. Only passenger names
  3. Only fuel purchases
  4. Only whether the route was profitable

Explanation

Traficom describes the digital tachograph as recording driving and rest times, speed, and distance. Its purpose is to support compliance, traffic safety, fair competition, and driver working conditions.

Question 47Bus Passengers

Which tachograph card is personal and used to record a driver's driving and rest times?

  1. Company card
  2. Workshop card
  3. Driver card Correct answer.
  4. Control card

Explanation

Traficom lists the driver card as personal and intended for recording the driver's driving and rest times. Company, workshop, and control cards serve different administrative, repair, or enforcement functions.

Question 48Bus Passengers

Before pulling away from a stop, which passenger-safety check matters most?

  1. That doors are closed and passengers are clear of the doorway and vehicle side Correct answer.
  2. That every passenger has paid in cash
  3. That the next stop name is already visible online
  4. That the driver starts before all boarding is complete

Explanation

Moving with an open door or a passenger near the doorway can cause a fall or trapping injury. The driver should close doors only when safe, check the stop area, and pull away smoothly.

Question 49Bus Passengers

Why is smooth acceleration and braking especially important in a city bus with standing passengers?

  1. Standing passengers can lose balance and be injured Correct answer.
  2. It makes the tachograph stop recording
  3. It cancels the need to check mirrors
  4. It allows the driver to ignore speed limits

Explanation

Many bus injuries happen inside the vehicle when passengers lose balance during harsh acceleration, steering, or braking. Smooth control is part of professional passenger safety.

Question 50Bus Passengers

A passenger using a wheelchair boards a bus equipped for wheelchair travel. What is the safest driver action before departure?

  1. Confirm the wheelchair space or restraint arrangements are safe before moving Correct answer.
  2. Start immediately to avoid delaying traffic
  3. Tell the passenger to hold the door pole instead
  4. Drive faster to reduce time spent onboard

Explanation

The driver must consider passenger safety before moving, especially for passengers using mobility aids. Departing only after the passenger and equipment are secure reduces fall and movement risk.
