How to Buy a Category D Driving Licence Test – A Complete Guide for Aspiring Bus Drivers
If you’re aiming to steer a passenger‑carriage vehicle—whether it’s a city bus, a school coach, or a tour minibus—you’ll need a Category D licence. Unlike a standard car licence (Category B), the Category D licence comes with a host of extra medical, theoretical, and practical requirements. One of the first practical steps you’ll encounter is the “Category D driving licence test” – the exam you must pass to prove you’re ready to take the wheel of a heavy‑vehicle passenger carrier.
In this post we’ll walk you through everything you need to know before you buy the test, from eligibility and paperwork to cost breakdowns, study resources, and the exact steps to schedule and sit for the exam. By the end you’ll have a clear, actionable roadmap that lets you purchase the test (or the necessary booking) with confidence and avoid costly mistakes.
1. Why “Buying” a Category D Test Isn’t About Money (It’s About Booking)
The phrase “buy a Category D driving licence test” can be misleading. In most jurisdictions you don’t purchase the test itself—you pay a fee to book a slot with the licensing authority or an approved driving school. The actual exam is free of charge once you’ve secured your appointment; the fee is simply an administrative cost for processing your application, reserving exam resources, and covering the examiner’s time.
Think of it as buying a ticket to a concert—once you have the ticket, you’re allowed entry, but the performance itself isn’t a product you can own. The same principle applies here: you “buy” the right to sit for the test.
2. Quick‑Start Checklist (What You Need Before You Can Book)
| # | Requirement | Details / How to Obtain |
|---|---|---|
| 1 | Valid Category B (car) licence | Must be held for at least 2 years. |
| 2 | Medical fitness certificate | Completed by an approved doctor; includes vision, hearing, cardiovascular health. |
| 3 | Theory test certificate (Category D) | Pass the mandatory theory exam first. |
| 4 | Professional driver’s training record (if required) | Minimum 30 hours of practical training with a certified instructor. |
| 5 | Proof of identity & residency | Passport/ID, utility bill, or tenancy agreement. |
| 6 | Payment method for booking fee | Credit/debit card, bank transfer, or approved e‑wallet. |
| 7 | Digital or printed application form | Most authorities now use an online portal; print if required. |
Tip: Keep a digital folder with scanned copies of all documents. When you log into the booking portal you’ll be asked to upload them; having them ready speeds up the process.
3. Understanding the Cost Structure
Below is a typical cost breakdown for a Category D licence in the United Kingdom, Ireland, Canada (Ontario), and Australia (NSW). Your local rates may differ, but the table gives a solid benchmark.
| Country / Region | Item | Approx. Cost (GBP) | Approx. Cost (Local Currency) | What It Covers |
|---|---|---|---|---|
| United Kingdom | Theory test fee | £23 | — | Computer‑based multiple‑choice test (40 questions). |
| United Kingdom | Practical test fee (standard) | £84 | — | On‑road driving assessment (incl. safety questions). |

4. Step‑by‑Step: How to Secure Your Category D Test Slot
Below is the exact workflow from the moment you decide to go for the test to the day you sit it down. Follow each step and you’ll never be caught off‑guard.
Step 1 – Confirm Eligibility
- Verify you have a valid Category B licence for at least two years.
- Check your medical certificate is current (valid for 2–5 years depending on age).
Step 2 – Pass the Theory Test
- Register via the official licensing website (e.g., DVLA for the UK, Road Safety Authority for Ireland).
- Pay the low‑cost theory fee (see table).
- Study using the official Highway Code plus a Category D specific handbook—see the Study Resources section below.
Step 3 – Gather Required Documents
- Medical fitness certificate (PDF).
- Theory test pass certificate (digital).
- Proof of professional training (if mandated).
Step 4 – Book the Practical Test
| Action | Where to Do It | What You’ll Need |
|---|---|---|
| Log into the online portal | Official licensing authority website | Email, password, ID number |
| Select “Category D Practical Test” | Choose date & time from the calendar | Payment method |
| Pay the booking fee | Credit/debit card, PayPal, bank transfer | Confirmation email will be sent |
Note: Slots fill up fast, especially in metropolitan areas. Book at least 4 weeks in advance.
Step 5 – Prepare for the Day
- Review the test route (if published).
- Get a full‑fuel‑tank and ensure the vehicle is road‑worthy (valid MOT/roadworthy certificate).
- Bring all original documents (license, medical, proof of identity).
Step 6 – Take the Test
- Arrive 15 minutes early.
- The examiner will check your documents, ask “hazard perception” questions, and then proceed with the on‑road assessment.
- If you pass, you receive a temporary Category D licence valid for 90 days while the full licence is printed.
Step 7 – After Passing
- Keep the temporary licence with you at all times.
- The permanent licence will be mailed to you (usually within 2–3 weeks).
5. Study Resources & “Buying” the Right Materials
Buying the test isn’t about purchasing an exam; it’s about investing in the right preparation tools. Below are the top resources you should budget for:
| Resource | Format | Approx. Cost | Why It’s Worth It |
|---|---|---|---|
| Official Category D Handbook | Hardcover / PDF | £12–£20 | Covers all legal and technical requirements. |
| Online Mock Theory Exams (e.g., Driving Test Success) | Subscription (monthly) | £7–£15 | Replicates the exact exam interface; tracks progress. |
| Video Hazard Perception Training | DVD / streaming | £10 | Visual training for quick decision‑making. |
| Professional Driving Instructor Packages | 10‑hour bundle | £300–£500 | Hands‑on practice; often includes a guaranteed test slot. |
| Medical Examination Voucher (approved clinic) | One‑off fee | £50–£120 | Guarantees a certified health certificate. |
How to Choose the Right Package
- Assess your learning style – visual learners thrive on video clips; reading‑oriented learners prefer the handbook.
- Calculate the total cost – add up the books, mock tests, and instructor fees. Compare that against a bundled “all‑in‑one” offer from a reputable school.
- Check reviews – look for testimonials from drivers who recently passed Category D.
6. Common Pitfalls & How to Avoid Them
| Pitfall | Consequence | Prevention Strategy |
|---|---|---|
| Booking a test before the medical certificate expires | Test will be cancelled; you’ll lose the fee | Set a calendar reminder 2 weeks before expiry; renew early. |
| Ignoring the hazard perception component | Unexpected failure in the practical test | Practice with online video clips daily; time yourself. |
| Bringing incomplete documents | Test may be postponed | Create a checklist and double‑check a day before. |
| Not familiarising yourself with the test vehicle | Reduced confidence; possible safety issues | Arrange a pre‑test “walk‑around” with the instructor. |
| Assuming the test date is fixed | Slots can be re‑allocated for emergencies | Keep your phone on; confirm the appointment 24 h prior. |
7. FAQ – Everything You Might Ask About Buying a Category D Test
Q1: Do I really need a medical certificate for a Category D licence?
Yes. Heavy passenger vehicles have stricter health standards. The certificate must be issued by a licensed occupational health doctor and cover vision, hearing, cardiovascular health, and neurological fitness.
Q2: Can I take the theory test online from home?
In most countries the theory test is still administered at a testing centre under supervision. However, you can register online and often pay online as well.
Q3: How long is the practical test valid after I pass?
You receive a temporary licence valid for 90 days. The permanent licence is mailed within 2–3 weeks, but you can legally drive with the temporary one during that period.
Q4: What happens if I fail the practical test?
You must re‑book and pay the same practical test fee again. Some jurisdictions allow you to reschedule within 14 days without paying an extra fee—check local rules.
Q5: Is there a minimum age for Category D?
Usually 21 years (or 24 for certain vehicle categories). Some regions allow 18‑year‑olds with a “Category D1” (small bus) licence. Verify your local age requirements before booking.
Q6: Can I use a foreign medical certificate?
Only if it’s certified and translated according to your licensing authority’s guidelines. Most accept EU/EEA certificates without translation; others need an official UK‑issued translation.
Q7: How many attempts am I allowed to take the theory test?
Typically unlimited, but you must wait at least 3 days between attempts. Some providers enforce a 2‑hour waiting period for online bookings.
Q8: Do I need a special vehicle for the practical test?
Yes. It must be a Category D‑approved vehicle with a valid road‑worthiness certificate (MOT in the UK). You can use a driving school’s vehicle or your own if it meets the criteria.
Q9: Are there discounts for unemployed or veterans?
Some local authorities offer reduced fees for unemployed individuals or veterans. Contact the licensing office directly to inquire.
Q10: What’s the best way to keep track of expiry dates (medical, licence, etc.)?
Set up calendar reminders on your phone and an email alert from the licensing authority (many provide a notification service). Keep a printed copy in your vehicle for quick reference.

9. Final Thoughts – Investing Wisely in Your Category D Journey
When you “buy” a Category D driving licence test, you’re really investing in your future as a professional driver. The cost is modest compared with the earning potential of a bus or coach driver—average salaries range from £30,000 to £45,000 per year in the UK, with overtime and night‑shift premiums boosting that figure.
By following the checklist, budgeting for the right preparation materials, and booking your test early, you’ll avoid the common pitfalls that cause delays and extra expenses. Remember:
- Plan ahead – schedule the medical exam and theory test first.
- Prepare thoroughly – use official handbooks, mock exams, and professional instruction.
- Double‑check documentation – a missing certificate can cancel your slot.
- Stay organized – keep a digital folder and calendar reminders for every deadline.
You’re now equipped with a step‑by‑step roadmap, cost breakdowns, study resources, and answers to the most common questions. All that’s left is to put the plan into action, click that “Book Test” button, and soon you’ll be behind the wheel of a bus, transporting passengers safely and confidently.
Good luck, and enjoy the ride to your new Category D licence!
