How to Get a Category D Driving Licence in Belgium?

Belgium lets you get Category D from just 18 if you complete vakbekwaamheid (professional competence) alongside it — but until you turn 21, code 121 restricts you to regular routes under 50 km, and only within Belgium. This piece covers what Category D authorises, exact age routes, and current requirements.

What Category D covers

Category D authorises any vehicle built to carry more than 8 passengers besides the driver, with no upper limit — buses, coaches, and everything in between. It automatically includes trailers up to 750 kg.

Minimum age

Without vakbekwaamheid, the minimum age is 24. With it, you can hold Category D from 18.

The code 121 restriction for 18-20 year olds

This is genuinely important to understand before you plan around the early route. If you get Category D with vakbekwaamheid before 21, code 121 appears on your licence: between 18 and 20, you’re limited to trips up to 50 km on regular transport routes within Belgium only; between 20 and 21, you can drive unrestricted within Belgium, but still not abroad. Only from 21 do all restrictions disappear.

You need Category B first.

To start training for Category D, you must already hold Category B.

The theory exam

You’ll sit two theory exams, each with 50 multiple-choice questions, requiring at least 40 correct answers. These certificates remain valid for 2 years. You can start the theory exam at 17 years and 9 months.

The practical exam

The practical exam splits into two tests: one on private terrain, and one on public roads — you can only move to the public road test after passing the private terrain component first.

Vakbekwaamheid: required separately for professional work

Holding Category D alone doesn’t authorise professional passenger transport. For that, you’ll need vakbekwaamheid (code 95), obtained either through the combined exam alongside your licence, or afterwards through the initial basic qualification exam.

Keeping vakbekwaamheid current

Vakbekwaamheid is valid for 5 years. Extending it requires one day of continuing education per year at a recognised training centre, earning 7 credit points per day — you’ll need 35 credit points accumulated over the 5 years to renew.

Documents you’ll need

• Your valid Category B licence
• A medical certificate confirming fitness for group 2 categories
• Proof of completed theory exams

Automatic transmission

If you pass your practical exam on an automatic-transmission vehicle, code 78 appears on your licence, restricting you to automatic vehicles for that category. Removing this restriction requires a new exam on a manual vehicle.

What Category D is genuinely used for

Most Category D holders go on to work in public transport or as tour coach drivers — the licence itself is the gateway. Still, real employment almost always requires vakbekwaamheid.

DE: adding a heavier trailer

DE extends Category D to vehicles combined with a heavier trailer over 750 kg, available once you already hold Category D.

D1, for comparison

D1 authorises smaller minibuses up to 16 passengers, with a lower minimum age of 21 (or 18 with vakbekwaamheid) — genuinely useful if you don’t need Category D’s unlimited passenger capacity.

Regional administration

Belgium’s regions—Flanders, Wallonia, and Brussels—each handle training and exams separately, so procedures and providers can vary depending on where you apply.

Tips that actually help

• WeigCarefully weigh code 121 restriction careou’re considering the age-18 route with vakbekwaamheid.
• Confirm your Category B is valid before starting Category D training.
• Plan your continuing education day each year to keep your vakbekwaamheid on track for its 5-year renewal.
• Check which region’s exam centres and procedures apply to you.

Regional administration: Flanders, Wallonia and Brussels

Belgium’s driving licence system is genuinely regionalised. Flanders (through examencentra like GOCA/KM), Wallonia, and Brussels each run their own exam centres, and the theory exam costs roughly €15 per attempt regardless of which region you sit it in. If you need your exam conducted in a language other than French or Dutch, expect a €50 surcharge to cover interpreter costs — genuinely useful to know if English is your stronger language.

What happens if you fail the theory exam twice

If you fail the theory exam twice in a row, Belgian regulations require you to complete a mandatory 12-hour theoretical training course at a recognised driving school before you can attempt the exam again. This course typically costs between €75 and €125. It’s a genuinely sensible safety net, but worth factoring into your budget and timeline if theory isn’t your strongest area.

The risk perception test

Before your practical exam, you’ll also need to pass a risk perception test, costing between €15 and €25 depending on the region. This assesses your ability to anticipate hazards in traffic situations — a genuinely important skill when you’re responsible for dozens of passengers rather than just yourself.

Financial support for training costs

Given the real cost of Category D training, several public bodies can help cover part or all of the expense depending on your circumstances. The OCMW (public social welfare centre), certain municipalities, and employment services, including FOREM (Wallonia), VDAB (Flanders), and Actiris (Brussels), may fund training, particularly if you’re pursuing bus driving as a route into stable employment. It’s genuinely worth checking with your local social service office before committing to a driving school, since eligibility and coverage levels vary by region and individual situation.

How D1, D1E, D and DE relate to each other in Belgium’s system

Belgium’s official mobility portal draws a clean distinction across these four categories. D1 lets you carry up to 16 passengers, with the vehicle capped at 8 metres in length, plus a trailer up to 750 kg. Full Category D removes both the passenger cap and the length restriction entirely — you can drive any bus or coach, of any size, with no upper limit on the number of people aboard. D1E and DE are simply trailer extensions for D1 only, letting you tow anything heavier than 750 kg once you hold the base category.

Genuine driver shortage context

Belgium’s transport sector, like much of Europe, faces real recruitment pressure for bus and coach drivers. Public transport operators and private coach companies alike have been actively promoting bus driving as a stable career path, often highlighting job security within your own region, four-day working weeks in some roles, competitive pay with fringe benefits, and genuine progression opportunities through further training. If you’re weighing Category D against other career options, this labour market context is genuinely worth knowing — demand for qualified drivers isn’t going away any time soon.

Training duration and lesson structure

Beyond the formal minimum lesson counts (10 or 20 hours of theory, depending on your existing category, and 20 or 25 hours of practical driving), most candidates find they need extra practice to feel genuinely confident behind the wheel of an 18-metre articulated bus or a full-size touring coach. Driving schools typically structure lessons around a mix of manoeuvring on private terrain first — reversing, tight turns, mirror checks — before progressing to public roads, motorways, and eventually more complex urban routes with multiple stops.

What a typical Category D course costs overall

While Belgium doesn’t publish one single fixed national price for Category D (costs vary by driving school, region, and how many lessons you personally need), a realistic total budget combining lesson fees, exam fees, and administrative costs typically runs into several thousand euros for candidates starting fresh from Category B, with candidates who already hold Category C generally paying less thanks to reduced training hour requirements.

After you pass: what your new licence actually looks like

Once you’ve passed both theory exams and both parts of your practical exam, your new licence will show Category D, along with any relevant codes such as 121 if you’re under 21 with vakbekwaamheid, or 96 and similar codes for any combination of categories you hold. When it arrives, check your printed licence carefully to confirm all your entitlements and any restrictions are recorded correctly.

Where this fits going forward

Category D in Belgium offers a genuine, well-structured route into professional bus driving, with real flexibility for younger candidates through the vakbekwaamheid system.

Recognising an existing foreign licence

If you already hold a Category D licence from another EU or EEA country, Belgium generally recognises it directly without requiring you to retake exams. However, you may need to register it locally and, in some cases, exchange it for a Belgian document depending on how long you’ve been resident. Licences from outside the EU/EEA are handled case by case, so contact your local commune or the relevant regional mobility service early to understand what’s required in your specific situation, since processes and reciprocity agreements vary considerably by country of origin.
