Sample Hungary KRESZ C1E Practice Questions

Try these sample questions to review concepts for the Hungary KRESZ C1E exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 30+ question experience with AI tutoring.

1Which combination falls within the Hungarian Category C1E entitlement?

A.A Category C1 drawing vehicle with a trailer over 750 kg, where the combination's maximum authorised mass does not exceed 12,000 kg

B.Any 40-tonne articulated lorry without an upper mass limit

C.A bus with more than sixteen passenger seats and any trailer

D.Every agricultural tractor towing two heavy trailers

Explanation: C1E includes a Category C1 drawing vehicle coupled to a trailer or semi-trailer over 750 kg, subject to a 12,000 kg maximum authorised mass for the combination. It also has a defined Category B drawing-vehicle route for certain combinations up to 12,000 kg; unrestricted heavy combinations require CE.

2Unless a lower posted limit applies, what is the maximum speed for a C1E goods-vehicle combination on a Hungarian motorway?

A.70 km/h

B.80 km/h

C.90 km/h

D.110 km/h

Explanation: The general motorway maximum for a motor vehicle towing a trailer is 80 km/h. The legal maximum is not a target: the driver must reduce speed for the load, visibility, road surface, wind, and other conditions.

3Unless signs impose a lower limit, what maximum speed applies to a C1E goods-vehicle combination on an express road or another road outside a built-up area?

A.50 km/h

B.60 km/h

C.70 km/h

D.90 km/h

Explanation: The general maximum for a motor vehicle towing a trailer is 70 km/h on an express road and on other roads outside built-up areas. A safe speed may be much lower because trailer stability and stopping distance depend on conditions.

4Outside a built-up area on a two-way road with one lane in each direction, what following-distance rule can apply when a C1E combination is longer than 7 metres?

A.Leave enough space for an overtaking vehicle to return safely between the combination and the vehicle ahead, unless an exception applies

B.Keep exactly seven metres from the vehicle ahead

C.Drive on the shoulder whenever another vehicle approaches from behind

D.Stop at the roadside after every five kilometres

Explanation: The KRESZ requires qualifying long vehicles on this type of road outside built-up areas to leave a suitable return gap for overtaking traffic. Seven metres is the trigger based on vehicle length, not the required gap itself.

5Why must a C1E driver know the combination's actual overall length before entering a constrained route?

A.Length affects swept path, available space, some traffic rules, and compliance with signed dimensional restrictions

B.Length alone determines the driver's blood-alcohol limit

C.A longer combination may ignore height restrictions

D.Vehicle length never changes after a trailer is coupled

Explanation: Coupling a trailer changes the vehicle's space requirements and can bring length-based rules or signed restrictions into play. The driver must know the configured combination rather than relying on the drawing vehicle's dimensions alone.

6On a multi-lane road, what is the normal lane-position principle for a C1E combination?

A.Keep to the right when circumstances permit, changing lanes only for a lawful manoeuvre or as traffic requires

B.Remain in the left lane because the combination is long

C.Straddle two lanes to stop others passing

D.Use the hard shoulder whenever traffic is slow

Explanation: The keep-right principle still applies to a vehicle combination. The driver also has to consider any lane-specific signs and special restrictions that cover heavy or long vehicles.

7Before parking and uncoupling a trailer, what should the driver confirm about the ground?

A.It is firm and sufficiently level to support the trailer, landing gear, and any wheel chocks without sinking or rolling

B.It slopes steeply so gravity will help uncoupling

C.It is soft enough for the landing legs to bury themselves

D.Ground condition is irrelevant once the engine is switched off

Explanation: A parked trailer must remain stable after the drawing vehicle moves away. Ground bearing strength and slope affect the landing gear, chocks, and risk of unintended movement or overturning.

8What must a driver check after attaching a trailer if the trailer could obscure the drawing vehicle's rear registration plate or lights?

A.That the combination displays the required visible trailer registration, lighting, reflectors, and signals

B.That the drawing vehicle's obscured lights remain switched off

C.That a handwritten plate is taped to the trailer

D.That only the left direction indicator works

Explanation: The completed combination must show its required rear identification and lighting equipment clearly. Coupling a trailer cannot leave required lamps, reflectors, or the trailer registration obscured or inoperative.

9In a conventional two-line pneumatic trailer-brake connection, what are the usual functions of the red and yellow lines?

A.Red supplies reservoir air; yellow carries the service-brake control signal

B.Red powers the lights; yellow supplies diesel fuel

C.Red controls steering; yellow inflates the tyres

D.Both are only decorative colour coding

Explanation: The red supply line charges the trailer system, while the yellow service line communicates the driver's braking demand. Drivers must use the correct coupling heads and check that both lines are secure and undamaged.

10What protective function is expected if the trailer's pneumatic supply line ruptures?

A.The trailer system should apply emergency braking as supply pressure is lost

B.The trailer service brakes become permanently stronger with no warning

C.The drawing vehicle automatically gains a higher speed limit

D.The trailer tyres inflate from the broken line

Explanation: A loss of supply is designed to trigger protective trailer braking rather than leave the trailer freely rolling. The driver should bring the combination to a safe stop and investigate; continuing can overheat applied brakes or worsen the defect.

About the Hungary KRESZ C1E Exam

The Hungary Category C1E KRESZ theory exam is administered by the Kozlekedesi Alkalmassagi es Vizsgakozpont (KAV) for drivers seeking qualification to operate vehicle combinations where the tractor vehicle is in Category C1 and its trailer or semi-trailer has a maximum authorised mass (MAM) exceeding 750 kg, provided the total authorised mass of the combination does not exceed 12,000 kg (as well as Category B tractors with trailers exceeding 3,500 kg up to 12,000 kg combination MAM). Under the official KAV curriculum effective 1 October 2024, candidates must pass two computer-based theory subjects: Kozlekedesi alapismeretek es jarmuvezetes elmelete (K: 25 questions, 35 points, 30 to pass, 25 minutes) and Szerkezeti es uzemeltetesi ismeretek (Szu: 25 questions, 25 points, 21 to pass, 25 minutes). Applicants are exempt from taking the M subject again since workplace and fire safety was certified during Category C1 qualification. Practical assessment includes a routine combination handling test and an on-road driving test. Key theory topics include combination speed limits (80 km/h motorway, 70 km/h rural/express, 50 km/h urban), mandatory following distance for combinations over 7 metres, off-tracking (nyomelteres), tail swing (farlesopres), jackknifing prevention, drawbar coupling protocols, pneumatic and overrun trailer brakes, and breakaway safety systems.

Hungary KRESZ C1E: Suggested Study Strategy

1Prepare for two distinct theory exams: Focus on K (combination road rules and articulated dynamics) and Szu (mechanical couplings and trailer pneumatic/overrun brake circuits).

2Understand off-tracking (nyomeltérés): In sharp curves, trailer wheels track inside the path of the tractor vehicle; drivers must make a wider approach before turning to prevent trailer wheels from clipping curbs, signs, or pedestrians.

3Know jackknifing (bicskázás) dynamics: Jackknifing occurs when the tractor's drive wheels lock or lose lateral adhesion while the trailer continues pushing forward; know the proper corrective response (release brakes, steer into the skid).

4Memorize the combination following distance rule: For combinations exceeding 7 metres outside built-up areas on single-lane roads, drivers must leave sufficient gap for overtaking vehicles to safely merge.

5Review coupling and uncoupling sequences: Master the safe order of operations (chocking trailer wheels, securing the hitch mechanism, locking safety pins, connecting air and electrical lines, and conducting visual and pull tests).

Frequently Asked Questions

What vehicle combinations can I drive with a Hungarian Category C1E driving licence?

A Category C1E driving licence entitles you to drive combinations of vehicles where the drawing vehicle is in Category C1 and its trailer or semi-trailer has a maximum authorised mass exceeding 750 kg, provided the maximum authorised mass of the combination does not exceed 12,000 kg. It also covers combinations where the drawing vehicle is in Category B and the trailer exceeds 3,500 kg, up to a total combination mass of 12,000 kg.

How many theory subjects and questions are on the Category C1E exam?

KAV requires two theory subjects for Category C1E: Kozlekedesi alapismeretek (K: 25 questions, 35 points, pass mark 30) and Szerkezeti es uzemeltetesi ismeretek (Szu: 25 questions, 25 points, pass mark 21). Across both tests, there are 50 questions total.

Is there a separate M (Munkavedelem) theory subject in the current Category C1E curriculum?

No. KAV's current Category C1E curriculum lists K and Szu as the two computer-based theory subjects and does not list a separate M examination for this category.

What are the speed limits for a Category C1E combination in Hungary?

Under Hungarian KRESZ regulations, vehicle combinations comprising a goods vehicle towing a trailer are limited to 50 km/h in built-up areas, 70 km/h on express roads and other rural roads outside built-up areas, and 80 km/h on motorways, unless specific signs post a lower limit.

What is the mandatory following distance rule for combinations exceeding 7 metres?

Under KRESZ Section 27, outside built-up areas on roads with a single lane in each direction, any vehicle or vehicle combination whose total length exceeds 7 metres must maintain sufficient distance from the preceding vehicle so that an overtaking vehicle can safely pull back in between them.

How do trailer pneumatic dual-line brake systems operate?

The red supply line charges the trailer air reservoirs from the tractor and triggers emergency spring/relay braking if disconnected or ruptured. The yellow service line transmits modulated control pressure from the driver's service foot brake to the trailer brake actuators.

How much does the KAV Category C1E theory exam cost?

Under the 2026 KAV fee table, the computer theory examination fee is HUF 12,700 per subject. For the two required Category C1E subjects (K and Szu), the total theory exam fee is HUF 25,400.
