You’ve been told you need ADR. Someone mentioned the Core module. Someone else said you need Packages on top of that. Your transport manager mentioned tanks. Now you’re sitting there wondering what on earth you actually need to book and how much it’s going to cost you.
Sound familiar? You’re not alone.
ADR training confuses a lot of drivers, not because it’s complicated, but because nobody ever sits down and explains it clearly. So that’s exactly what we’re going to do here.
What Is ADR and Why Do You Need It?
ADR is the European Agreement Concerning the International Carriage of Dangerous Goods by Road. In plain English it’s the legal certification you must hold if you’re transporting hazardous materials on UK roads.
Without a valid ADR licence, you cannot legally carry dangerous goods above certain quantity thresholds. It’s not a box-ticking exercise. It’s a legal requirement, and enforcement on UK roads is real.
Your ADR licence lasts five years and is issued by the SQA as a Vocational Training Certificate a physical card you carry with every dangerous goods load.
First Things First The Core Module
Every ADR qualification starts with the Core module. No matter what type of dangerous goods you carry, no matter what vehicle you drive you start here. Think of it as the foundation everything else is built on.
The Core module covers:
- The nine classes of dangerous goods and how to identify them
- How dangerous goods must be labelled, marked, and placarded on your vehicle
- Transport documentation what paperwork you need and what it must say
- Emergency procedures what you do if something goes wrong on the road
- Your responsibilities as a driver under ADR regulations
The Core module alone is not enough to legally carry dangerous goods. It must be paired with at least one specialist module that matches the type of load you’re carrying. That’s where drivers often get confused and where getting it wrong becomes a serious problem.
The Specialist Modules Matched to Your Load
Once you’ve completed the Core, you need the specialist module that covers the type of dangerous goods you’re actually transporting. Here’s how they break down:
Packages and Articles for most HGV drivers
This is the most common specialist module and the one the majority of truck drivers need. If you’re driving a curtainsider, box vehicle, or rigid carrying dangerous goods in boxes, drums, IBCs, or any packaged form this is your module.
It covers:
- Correct loading and stowage of packaged dangerous goods
- Segregation rules what can and can’t travel together
- Checking packaging integrity before accepting a load
- Class-specific rules for Classes 2, 3, 4, 5, 6, 8, and 9
If you drive a Cat C rigid curtainsiders, box vehicles, skip lorries the Packages module paired with the Core is your standard route.
Tanks for tanker and bulk liquid drivers
If you’re operating a vehicle with a fixed tank or portable tank container over 3,000 litres, you need the Tanks module on top of Core and Packages. This is mandatory for:
- Petrol tanker and fuel delivery drivers
- LPG and gas distribution drivers
- Chemical tanker operators
- Anyone moving bulk liquids in tank containers
The Tanks module covers the specific risks around bulk liquid transport pressure, spillage, tank inspection, filling limits, and the additional placarding requirements that come with tanker operations. It’s a 1.5-day addition and can be taken alongside the Packages module in a combined 5-day course.
Class 1 Explosives
This is a specialist-only qualification and one that very few UK training providers are approved to deliver. If you work in:
- Fireworks distribution
- Military or defence logistics
- Mining and quarrying supply
Then you’ll need Core plus the Class 1 module. It’s a 2.5-day course in total and runs on limited dates given how few providers are licensed to teach it.
Class 7 Radioactive Materials
Another specialist qualification, and notably one that doesn’t require an HGV licence so motorcycle and car drivers sometimes hold this too. It applies to:
- Medical isotope transport
- Nuclear industry logistics
- Hospital and research institution supply chains
Like Class 1, this is a 2.5-day course and only available from a small number of approved providers.
So Which Course Do You Actually Book?
Here’s a straight answer based on your vehicle and load type:
Cat C+E artic driver or petrol tanker operator?
You need the full combined course Core, Packages, and Tanks. That’s a 5-day course covering Classes 2, 3, 4, 5, 6, 8, and 9. It’s the most popular route and the one that covers the widest range of loads.
Cat C rigid driver curtainsiders, box vehicles, skip lorries?
You need Core plus Packages. That’s a 3.5-day course. Ideal if you’re not operating tanks over 3,000 litres.
Fuel delivery or petrol tanker driver only?
Core plus Tanker module with Class 3 Flammable Liquids. That’s a focused 5-day route without the full packages element.
Gas distribution driver BOC, Calor, or similar?
Core plus Packages with Class 2 Gases. A 3.5-day course specifically required by gas distribution operators.
Pharmaceutical, veterinary, or hospital logistics?
Core plus Packages with Class 6 Toxic and Infectious Substances. Essential for chemists, vets, hospitals, and pharmaceutical logistics providers.
Already hold a Packages ADR but need to add Tanker?
You can add just the Tanker module a 1.5-day addition without repeating the full course, provided your existing Packages ADR certificate is still valid.
The ADR Licence and Your Driver CPC Two Birds, One Stone
Here’s something worth knowing that a lot of drivers miss entirely. ADR training counts toward your Driver CPC hours.
The full 5-day combined course earns you 35 CPC hours which is the entire five-year CPC requirement completed in a single week. Even the shorter courses earn between 14 and 21 hours. If your CPC is due for renewal, booking your ADR at the right time means you knock out both requirements in one go.
What Happens If You Get It Wrong?
Driving with the wrong ADR certificate or no certificate at all isn’t just a paperwork issue. The consequences are real:
- Prohibition notices and vehicle being stopped at roadside checks
- Fines for both driver and operator
- Operator licence implications for your employer
- Personal liability if an incident occurs and inadequate training is found
DVSA enforcement on dangerous goods is active, and roadside checks specifically look at whether drivers hold the correct module for the load they’re carrying. Core-only isn’t a defence when your trailer is loaded with packaged hazmat.
What to Look for in an ADR Training Provider
Not all ADR training is equal, and this matters more than you might think. A few things worth checking before you book:
- Are they an actual training provider, not a broker passing you on to someone else?
- Do their instructors hold DGSA (Dangerous Goods Safety Adviser) qualifications?
- Are they approved to deliver Class 1 and Class 7 if you ever need them?
- Do exam fees and VAT come included in the price, or are they added on later?
- What’s their first-attempt pass rate?
For drivers based in Surrey and the South East, EP Training is a long-established provider with over 15,000 drivers trained, a 97% first-attempt pass rate, DGSA-qualified instructors, and transparent all-in pricing. They’re also one of the very few UK providers approved for Class 1 and Class 7 specialist courses which matters if your work ever takes you into those sectors.
The Short Version
ADR isn’t complicated once you match the module to the load. Here’s the quick reference:
- Core module required by everyone, but never enough on its own
- Packages module rigid and artic drivers carrying packaged DG
- Tanks module add this if you’re operating tanks over 3,000 litres
- Class 1 explosives, specialist route, limited providers
- Class 7 radioactives, specialist route, HGV licence not required
If you’re still not sure which course applies to your work, a quick phone call to a good training provider will give you a straight answer in five minutes. Don’t guess the wrong certificate is as problematic as no certificate at all.
