Step 1. The big picture
In one sentence…
D+E passenger combinations combine carrying people with the dynamic complexity of a heavy trailer. You must master the scope of the licence, the specific exam and the practical consequences of driving a D-category bus with a trailer of more than 750 kg.
Step 2. The syllabus
2.1Scope of the licence
The D+E licence authorises a D-category bus with a trailer of more than 750 kg. The authorisation refers to the combination formed by the passenger vehicle and its trailer.
- To obtain it you must hold a valid D licence, meet the minimum age of 24, and pass the specific theory test and the practical test with the combination.
- The specific theory test has 20 specific questions, a maximum of 2 errors and 20 minutes. The margin for error is small, so it is worth studying situations and not just definitions.
- Distinguish the base bus, the authorised trailer and the obligations of the combination. Mixing up a single vehicle and a combination causes common mistakes.
2.2Base vehicle and trailer
The base vehicle belongs to the D licence, but once you hitch a trailer of more than 750 kg MAM you enter the logic of the D+E.
- The trailer changes length, tracking on bends, required space and stability. That is why specific preparation and a practical test with the combination exist.
- Remember that the trailer cannot be used to carry passengers. This rule rules out answers that treat the trailer as an extension of the passenger compartment.
- Documentation, coupling, connections and applicable limits must be checked before the service. Knowing the licence's authorisation is not enough.
2.3Passenger safety
Carrying passengers turns smoothness into a safety requirement. Sudden acceleration, braking and turning affect comfort and stability.
- The margin must be greater than in a single vehicle because every manoeuvre affects two connected masses and the people inside them.
- If a situation forces you to improvise, you probably reacted too late. Correct driving is based on anticipation, space and early decisions.
- In theory questions, look for the option that protects passengers and other road users without forcing the manoeuvre or reducing the safety margin.
2.4Manoeuvrability and space
The trailer changes turns, roundabouts, joining traffic and reversing. You need more space and less improvisation than with a single vehicle.
- Do not start a manoeuvre if you cannot complete it without encroaching on or unsafely blocking a space. Just enough room is usually a trap.
- In turns, watch the trailer's tracking and protect areas with pedestrians or cyclists. The risk is not only ahead of you.
- When reversing, use clear reference points and small corrections. If you lose sight of the critical area, stop before continuing.
2.5Prior checks
Before the service, check the coupling, electrical connections, wheels, brakes, lights, signalling and fixings. These are applied safety, not bureaucracy.
- Do not wait to notice a fault while under way. Detecting an anomaly late reduces your margin to stop and protect passengers.
- Checking the trailer is just as practically important as checking the lead vehicle. A defect at the back affects the whole trajectory.
- When the question talks about starting a service, read that phrase as a clue about preparation and prior checks.
2.6How it appears in the exam
The specific D+E exam covers the service, coupling, manoeuvring and passenger safety. Study each rule together with a practical consequence.
- If an answer plays down the trailer, be suspicious. The central idea is that it changes driving, stability and journey preparation.
- If an answer forgets about the passengers, also be suspicious. Smooth, anticipatory driving is part of safety.
- Practise separating three levels: what the licence authorises, what you check before setting off, and how you manoeuvre with a safety margin.
Step 3. Key points
If you only have a minute before the exam, revise this.
- 1.Memorise that the D+E requires holding a valid D licence.
- 2.Remember the licence's minimum age of 24.
- 3.Link the specific exam to 20 specific questions, a maximum of 2 errors and 20 minutes.
- 4.Identify a D-category bus with a trailer of more than 750 kg as the authorised combination.
- 5.Check documentation, coupling and limits before the service.
- 6.Do not use the trailer to carry passengers.
- 7.Increase the manoeuvring margin because of the trailer and the passengers.
Step 4. Exam traps
Mistakes the DGT uses again and again on this topic.
- Confusing the D licence with the D+E and forgetting the effect of the trailer.
- Accepting that the trailer carries passengers when the applicable rule says otherwise.
- Forgetting that the specific exam has 20 questions, a maximum of 2 errors and 20 minutes.
- Thinking the technique for a single vehicle is enough for the combination.
- Not checking the coupling or connections before starting the service.
Step 5. Quick check
Four real exam questions on what you have just read.
At age 21 and with accelerated CAP, D+E is limited in passenger transport to:
Step 6. Frequently asked questions about regulations for passenger combinations
- Before moving off with a bus towing a trailer, which check is essential for passengers boarding or alighting?
- That boarding and alighting have finished safely and the doors are closed. Check that boarding and alighting have finished safely and the doors are properly closed. Do not move off while someone is boarding or alighting or travel with doors open. This does not replace other checks of the vehicle, trailer or driving position.See full question
- If applying the 10% error limit in the D1+E or D+E specific knowledge test gives a decimal result, what does Annex VI.B.3 of the General Driver Regulations require?
- The next highest whole number applies. Use the next higher whole number. The prescribed percentage is 10% of all questions, not 20%. For example, a 20-question test allows at most 2 errors. If the regulatory calculation produces a decimal, the next whole number is used under that annex.See full question
- To obtain the D1+E licence as a general rule, the applicant must previously hold:
- A D1 licence. Category D1+E extends the authorization of the D1 licence, so the applicant must already hold that base licence.See full question
- One of the reduced ages for obtaining D+E is 23 when the applicant:
- Holds CAP in the accelerated initial qualification category. The DGT states that D+E may be obtained at age 23 if the applicant holds CAP in the accelerated initial qualification category.See full question

- B+ERegulations for combinations
In B+E you must study authorised masses, coupling, load distribution, the stability of the combination and specific signalling for driving with a trailer or semi-trailer within the framework allowed by this class. The key is always to think of the towing vehicle and trailer as a single unit that is longer, heavier and slower to react.
- C+ERegulations for heavy combinations
In C+E you study articulated goods combinations or ones with a heavy trailer: correct authorisation, coupling, restrictions on mass and length, and dynamic behaviour more demanding than a rigid vehicle. The goal is to recognise when the rules, the road or the combination's configuration require greater caution and margin.

Preventive maintenance of D+E combinations prevents breakdowns, improves braking and cornering, protects passengers and reduces exam mistakes. Study it as preparation for the service, not as a task unrelated to the driver.
