Transportation of Dangerous Goods (TDG) Training Certificate Test (Road)
There is no government TDG exam: under Part 6 of the TDG Regulations, your employer issues a training certificate, valid 36 months for road transport, once it is satisfied you are adequately trained, usually after a course and test set by the employer or a training provider. Our mock test uses 50 questions and an 80% target, a VoltExam practice format rather than an official standard. It covers the regulation topics training must address: classification, shipping documents, dangerous goods marks, means of containment, ERAPs, reporting and the Emergency Response Guidebook.

How to get certified
- 1
Confirm your TDG duties
List what you do with dangerous goods: handling (loading, unloading, packing), offering for transport (classifying, documenting, choosing a carrier) or transporting. Training only needs to cover the topics that relate directly to those duties and goods.
- 2
Complete training on the section 6.2 topics
Take your employer's training or a provider's course covering the relevant topics: classification, shipping names and schedules, documentation, dangerous goods marks, means of containment, ERAPs, reporting, safe handling, equipment use and emergency measures.
- 3
Pass your employer's or provider's assessment
There is no government test. Your employer or training provider decides how to check that you are adequately trained, often with a written or online test.
- 4
Get your certificate issued and signed
Your employer issues the certificate with its name and address, your name, the aspects you are trained for and an expiry date marked "Expires on". You and the employer sign it. Self-employed people issue and sign their own.
- 5
Carry it and show it on request
Keep the certificate or a copy with you when you handle or transport dangerous goods and give it to an inspector immediately on request. Until you are certified, work only under the direct supervision of a certificate holder who is present.
- 6
Retrain before it expires
A road certificate expires 36 months after issue (24 months for air). Plan refresher training early, and get a new certificate from each new employer, since certificates are not transferable.
How to study
- Learn the description order cold: UN number, shipping name, class, subsidiary class in parentheses, packing group, for example "UN1203, GASOLINE, Class 3, PG II".
- Know your numbers: 450 L splits small from large containers, placards are 250 mm and labels 100 mm, UN numbers on tanks are 65 mm, and the placard exemption stops at 500 kg gross.
- Practise reading Schedule 1 rows: UN number, shipping name, class, packing group, special provisions, limited quantity index and ERAP index.
- Match each Part 8 report to its recipient: local authority first, then CANUTEC and the consignor, then a written 30-day report to Transport Canada.
- Walk through the ERG: find a UN number in the yellow pages, follow it to the orange guide and check the green tables when the entry is highlighted.
- Check which special cases remove training (the 150 kg case, limited quantities) and which do not (the 500 kg case).
Frequently asked questions
Is there a government TDG test or licence?
No. The TDG Regulations set no government exam or licence. Your employer issues a training certificate once it has reasonable grounds to believe you are adequately trained; any test comes from your employer or training provider.
How long is a TDG certificate valid?
For road, rail or marine transport it expires 36 months after it is issued. For air transport it expires after 24 months. The expiry date must appear on the certificate after the words "Expires on".
What is the pass mark for the TDG test?
No official pass mark is published, because the test is set by your employer or training provider. Our mock exam uses 50 questions and an 80% target as a practice standard; ask your provider what score it requires.
Can I take my TDG certificate to a new job?
No. Certificates are not transferable. Each employer must satisfy itself that you are adequately trained and issue its own certificate, so a person who works for two employers holds two certificates.
Do I need TDG training if I only load and unload trucks?
Yes. Loading and unloading is handling, and Part 6 applies to anyone who handles, offers for transport or transports dangerous goods. Until you are certified you may do the work only under the direct supervision of a certificate holder who is present.
Do small quantities need TDG training?
Sometimes not. The 150 kg gross mass special case for consumer quantities (section 1.15) and properly marked limited quantities (section 1.17) remove Part 6 when all their conditions are met. The 500 kg special case (section 1.16) does not remove training.
What happens if an inspector asks for my certificate?
You must give the inspector your certificate, or a copy, immediately. Your employer must provide its training records within 15 days of a written request and keep them until two years after the certificate expires.
