1What is the maximum vehicle length permitted for a small bus driven under driving licence Category D1?
A.7.50 metres
B.8.50 metres
C.8.00 metres
D.9.00 metres
Explanation: According to the Swedish Driving Licence Act (Körkortslagen), Category D1 authorizes driving buses designed and constructed to carry no more than 16 passengers in addition to the driver, with a maximum length not exceeding 8.00 metres.
2What is the maximum number of passenger seats permitted in a bus driven with a Category D1 licence?
A.8 passengers in addition to the driver
B.16 passengers in addition to the driver
C.12 passengers in addition to the driver
D.24 passengers in addition to the driver
Explanation: Under Swedish law (Körkortslagen 1998:488), Category D1 allows driving a bus designed and constructed to transport a maximum of 16 passengers in addition to the driver. Vehicles carrying more than 16 passengers require a full Category D licence.
3Under TSFS 2013:63, at what speed must the speed limiter (hastighetsregulator) on a bus be set?
A.Buses are exempt from speed limiter requirements
B.So that the bus cannot exceed 90 km/h
C.So that the bus cannot exceed 80 km/h
D.So that the bus cannot be driven faster than 100 km/h
Explanation: TSFS 2013:63 (14 kap. 1 §) requires buses, and lorries over 3,500 kg, to have a speed limiter; on a bus it must be set so the bus cannot be driven faster than 100 km/h (90 km/h for lorries). The limiter only caps top speed; the driver must still keep to lower limits, such as 90 km/h for a heavy bus when not all passengers have belted seats.
4How must emergency exits (nödutgångar) in a small bus be indicated and maintained according to safety regulations?
A.Clearly marked with approved signs and kept completely clear
B.They only need markings if the vehicle carries more than 20 passengers
C.They may be blocked by foldable luggage racks as long as passengers can move them quickly
D.They must have mechanical padlocks engaged during transit to prevent accidental opening
Explanation: Emergency exits (doors, designated windows, and roof hatches) must feature clear, luminescent or illuminated emergency signage and operating instructions. They must remain completely free of baggage, luggage, or temporary obstructions at all times.
5Where must emergency hammers (nödhammare) be positioned inside a small bus equipped with emergency break-out windows?
A.Stored securely inside the locked glovebox or luggage trunk
B.Placed underneath the rear passenger bench seat
C.Carried inside the driver's pocket or personal bag
D.In visible brackets next to the emergency windows
Explanation: Emergency glass-breaking hammers must be positioned in plain sight in dedicated, easily reachable wall brackets adjacent to each designated emergency window so that passengers can instantly shatter the toughened glass in an emergency.
6What is the primary safety purpose of an emergency roof escape hatch (taklucka) in a small bus?
A.It serves solely for hot-weather interior ventilation when the auxiliary air conditioner is off
B.An escape route if the bus ends up on its side and the doors are blocked
C.It acts as an inspection access panel for maintaining roof-mounted air filter housings
D.It allows exterior firefighters to pump water directly into the passenger cabin
Explanation: The roof hatch (taklucka) functions as a designated emergency escape exit designed to be opened from both inside and outside. If a minibus overturns onto its side, side doors and windows become blocked or inaccessible, making the roof hatch the primary escape portal.
7Which requirement applies to the handheld fire extinguisher (brandsläckare) carried in a Category D1 small bus?
A.It can be stored in the external trailer box as long as the key is in the ignition
B.Any water-based fire extinguisher is acceptable provided it has at least 1 litre capacity
C.At least one approved extinguisher (e.g. class ABC II or 34A/183B), sealed, checked as the manufacturer prescribes, easily accessible in the passenger compartment and signposted unless clearly visible
D.Fire extinguishers are only legally required if carrying hazardous chemical cargo
Explanation: TSFS 2013:63 (40 kap. 5 §) requires every bus to carry at least one fire extinguisher of at least class 34A or 183B (or ABE II/ABC II). It must be functional and checked according to the manufacturer's instructions, sealed (plomberad), easily accessible in the passenger compartment, and marked with a sign unless it is clearly visible.
8What is good practice for the first-aid kit (förbandslåda) carried in a passenger bus?
A.Keep it accessible and complete, with sterile items in date
B.It is only recommended and can be replaced with standard wet wipes
C.It must be locked away in the engine bay to maintain low storage temperatures
D.It is only required if the journey exceeds 150 kilometres from the depot
Explanation: A first-aid kit should be kept complete and easy to reach. The driver is responsible for verifying during safety checks that contents are intact, hygienic, and that sterile bandages have not expired.
9During a pre-trip inspection of an electro-hydraulic wheelchair lift (rullstolslyft), which check is essential before passenger boarding?
A.Verifying that the hydraulic oil has been completely drained to reduce vehicle weight
B.Testing whether the lift can raise three adult standing passengers simultaneously to verify overload tolerance
C.Checking roll-stop barriers, smooth deployment, hydraulic hose integrity, and the emergency manual pump
D.Disabling the audible warning buzzer to ensure quiet operation in residential areas
Explanation: The driver must verify that the lift platform operates smoothly, that automatic roll-off barriers latch securely, that hydraulic lines show no leaks, and that the manual hand pump works in case of electrical failure.
10How does a drive-interlock system function on a minibus equipped with a passenger wheelchair lift or folding ramp?
A.It limits the top speed of the bus to 50 km/h while driving on motorways
B.It stops the bus moving off while the lift, ramp or doors are open
C.It automatically disables the vehicle's service brakes when the ramp is folded
D.It restricts engine power only when the vehicle is driven in reverse gear
Explanation: Accessible minibuses are commonly fitted with a drive-interlock mechanism. This system disables the gear selector or starter motor while the lift is active or the ramp is extended, preventing accidental drive-aways that could crush passengers.

About the Kunskapsprov D1 Exam

Independent Category D1 practice by OpenExamPrep. This English-language multiple-choice study adaptation (not an official translation or simulation; the official test is taken in Swedish) covers the theoretical requirements for Sweden's category D1 small bus (mellanstor buss) driving licence. Category D1 authorises driving buses constructed for a maximum of 16 passengers in addition to the driver, with a maximum length of 8.00 metres, coupled with a light trailer up to 750 kg. Trafikverket administers the computer-based knowledge test (Kunskapsprov D1) at official Förarprov test centres across Sweden. The examination tests five core areas: vehicle knowledge and manoeuvring, environment, traffic safety, traffic rules, and personal conditions. Candidates must master passenger safety, emergency equipment (nödutgångar, nödhammare, taklucka, brandsläckare), wheelchair restraint systems, school transport rules (skolskjuts), speed limits, bus stop priority (bussregeln), bus lanes (kollektivkörfält), and group 3 medical requirements. The exam consists of 60 questions delivered in 40 minutes, where 55 questions are scored and 5 are unscored trial questions. A score of 44 or higher is required to pass, and a passed D1 theory test is valid for 1 year.

Kunskapsprov D1: Suggested Study Strategy

1Master the D1 specification limits: maximum 16 passengers plus driver, maximum vehicle length of 8.00 metres, and light trailer up to 750 kg.
2Memorise the bus speed limit rules: a heavy bus may travel up to 100 km/h where the limit allows only if every passenger over three years old has a seat with a seatbelt; otherwise the ceiling is 90 km/h.
3Understand the bus stop rule (bussregeln): on roads with a speed limit of 50 km/h or less, other vehicles must yield to a bus signaling to leave a bus stop; on roads above 50 km/h, the bus driver must yield.
4Review winter tyre rules: a heavy bus (over 3.5 tonnes) and its trailer need winter tyres from 10 November to 10 April regardless of road conditions, with at least 5 mm tread on all of the bus's tyres; a light bus follows the 1 December to 31 March winter-conditions rule.
5Know the emergency equipment: clearly marked, unobstructed emergency exits (doors, break-out windows with hammers, roof hatches) and at least one approved, sealed and checked fire extinguisher accessible in the passenger compartment.
6Study passenger restraint and school transport rules: the driver, together with any staff or escorts, must see that children under 15 use belts or child restraints, and a school bus shows the yellow skolskjuts sign with a red border, front and rear, with amber flashing lamps.
7Remember licence renewal: D1 is renewed every 5 years, with a health declaration and vision certificate under age 45 and a medical certificate (läkarintyg) from age 45.
