Look Inside the Book

These are real pages from the book. The table of contents is the full one: 9 parts and 64 topics.

The Problem Isn't You. It's How It Was Explained to You.

You're in the exam with a UN number and a question about its tunnel code. You open Table A and you're staring at 20 columns of codes, flicking back and forth while the clock runs.

ADR explains those columns in Chapter 3.2, in paragraph after paragraph of legal prose. Nothing on the page shows you which column sits where, so under time pressure the prose simply doesn't come back.

Table A columns 1 to 20, grouped: identity, packaging, tanks, carriage, emergency.

In this book, Table A is one page: the 20 columns split into 5 coloured blocks, identity, packaging, tanks, carriage and emergency. You see which block a column belongs to before you read a word.

The same goes for the 9 classes, the UN packaging mark, the orange plate, the 1.1.3 exemptions and the 1.1.3.6 points calculation: each one has its own page.

You go from UN number to answer column by column, without rereading the chapter to work out where to look.

One Page, One Topic, All Clear

Think of it this way:

A load is going out: cans of petrol and a few drums of corrosives on one van. Your manager asks a simple question: under the 1.1.3.6 limit, or orange plates?

In the book you open the 1.1.3.6 page and see the routine drawn in a row: transport category, multiplier, total against 1,000 points.

Package danger labels: diamond, normally at least 100 × 100 mm, line 5 mm inside the edge

Same with the Table A columns, the UN packaging mark, the orange plate, the transport document and the instructions in writing: each one on its own page.

DGSA Illustrated: Core & Road is 9 parts and 64 topics, all drawn, and it ends with worked case studies, a revision checklist and the most common mistakes at a glance.

What you see drawn, you don't have to memorize.

Frequently Asked Questions

Is it for me if I've worked in transport for years and now my company needs me to be its DGSA?

Yes. It starts from the map of ADR and goes all the way to 1.1.3.6 points, the adviser's duties and worked case studies. It's visual, not basic.

Where does the content come from?

It's written for the UK DGSA exam, Core and Road modules. The content is checked against ADR 2025, the edition in force until the end of 2026, and the CDG Regulations 2009 as applied in Great Britain. ADR 2027 applies from 1 January 2027: if your exam is after that date, check which edition your course and exam centre use.

Is it official material?

No. It's an independent illustrated study book. It isn't issued or endorsed by SQA, any government department or UNECE, and it doesn't give you a certificate: the DGSA certificate comes only from passing the exam.

Does it replace the course or ADR itself?

No. It's a study companion to use alongside your training and the official ADR text, which always takes precedence. In the exam you'll work from ADR itself, so check with your exam centre what you can take in. This book is for learning where to look in ADR before you get there.

Are the practice questions the ones from the exam?

No. The exam-style questions are written for this book to help you practise. They aren't official exam questions.

When and how do I get it?

The book and the 2 gifts arrive as a PDF by email, at the address you enter at checkout.

Do I have to pay every month?

No. It's a one-off payment, with no subscription.

Can I have it on paper?

Yes. The PDF prints at home or at any print shop, so you can keep it next to your copy of ADR.

How does the refund work?

You have 30 days. We refund everything if the file won't open, if the book isn't what you see on this page, if you were charged twice or if the email doesn't arrive: just email us.

Before You Close This Page

No more rereading ADR with nothing sticking.

Table A's 20 columns, drawn in 5 blocks you can picture.
