If you’ve booked onto an ADR course, or you’re thinking about getting your certificate, the exam is probably the part you’re most nervous about. That’s completely normal. Most candidates have never sat anything like it before — this is not a standard driving test, and the questions cover some very specific territory around dangerous goods legislation, hazard classes, and emergency procedures.
So this page walks you through exactly what the ADR test looks like. Specifically, it covers the pass marks you need to hit in 2026, the types of questions that come up in each module, and where to find free ADR mock test practice before your exam date.
What Is the ADR Exam?
ADR stands for Accord Dangereux Routier — the European agreement that governs the international carriage of dangerous goods by road. In the UK, drivers who transport hazardous materials professionally must hold a valid ADR certificate. This is a legal requirement, not an optional qualification.
The exam itself is a multiple-choice test. For every question, you receive four options and must select the correct one. There are no trick questions designed to confuse you. However, the wording can be very precise, and two options can look almost identical if you read them too quickly.
That precision is exactly why working through ADR test questions in advance makes such a difference. The more familiar you are with how ADR questions read, the more confident you will feel when it counts.
ADR in the UK
The ADR agreement applies throughout the UK and Europe. Any driver carrying dangerous goods by road professionally is legally required to hold a valid ADR certificate for the relevant categories of goods they carry.
ADR Exam Pass Mark 2026
The ADR exam is split into separate modules. Which ones you sit depends on the certificate you are working towards. Here is the full breakdown for 2026:
| Module | Duration | Questions | Pass Mark | Required % |
|---|---|---|---|---|
| Core / Basic | 60 minutes | 30 questions | 20 correct | 66% |
| Tanker Specialist | 45 minutes | 15 questions | 10 correct | 66% |
| Class 1 – Explosives | 45 minutes | 15 questions | 10 correct | 66% |
| Class 7 – Radioactive | 45 minutes | 15 questions | 10 correct | 66% |
Each Module Is Marked Separately
If you’re going for a full ADR certificate covering multiple specialist categories, you’ll sit additional modules on top of the core exam. You need to pass every module individually – a high score in one won’t compensate for a fail in another.
How to Use Free ADR Mock Tests Before Your Exam
The single best thing you can do before your ADR exam is work through as many mock test questions as possible. Free ADR mock tests are available online, and they give you a realistic feel for the format, the phrasing, and the pressure of answering under timed conditions.
When you practise, don’t just check whether you got the answer right — find out why the correct answer is correct. ADR questions often turn on a specific regulation or a precise definition. The more comfortable you are with the language of the legislation, the more straightforward the real exam will feel.

How Long Is an ADR Certificate Valid?
ADR Certificate Validity
Your ADR training certificate stays valid for five years from the date of issue. Before it expires, you must complete a refresher course to keep it current. If it lapses, you lose the legal right to carry dangerous goods by road — so watch the expiry date well in advance.
Tips for Passing Your ADR Exam First Time
Here are the habits and strategies that separate candidates who pass first time from those who need to resit.
Read every question twice
The wording in ADR questions is precise. Because two options can look almost identical, take your time and read each one carefully. There are no marks for speed, so use every second you have.
Know your hazard classes cold
Class numbers and their definitions appear constantly across the core module. When you can recall them without thinking, you save time and make fewer errors under pressure.
Do not skip the legislation sections
Questions about the Instructions in Writing, the transport document, and driver responsibilities make up a significant portion of the core paper. Fortunately, these are straightforward to learn — so do not leave them until the night before.
On exam day
Use free ADR mock tests in the week before your exam
Sitting timed practice tests sharpens your focus and gets you used to making quick, accurate decisions. Furthermore, the format becomes familiar — and familiar is far less stressful on exam day.
Pay attention during the course
Everything in the exam comes directly from your ADR training. Candidates who engage properly during the course rarely struggle on exam day, because the questions do not feel unfamiliar.
