ADR vs. DG Training: What’s the Difference & Which Do You Need?

25/03/2025

Transporting hazardous materials safely and legally requires specialised training. However, with various certification options available, many operators and drivers may be unsure whether they need ADR (Accord Dangereux Routier) training or Dangerous Goods Awareness (DG) training. While both are related to the safe handling and transportation of hazardous materials, they serve different purposes. Understanding these distinctions is essential to ensure compliance, avoid penalties, and maintain a safe working environment.

What is ADR Training?

ADR training refers to the certification required for drivers transporting dangerous goods by road under the International Agreement concerning the International Carriage of Dangerous Goods by Road (ADR). This training ensures that drivers understand the specific legal, safety, and emergency response requirements for handling hazardous materials on public roads.

Who Needs ADR Training?

ADR training is mandatory for:

  • Drivers transporting dangerous goods in tanks, bulk containers, or specific packaged goods.
  • Drivers transporting dangerous goods above certain quantities per vehicle in packages including IBCs.
  • Drivers handling substances that fall under ADR classifications, such as flammable liquids, corrosives, and toxic materials.

What Does ADR Training Cover?

Certification Validity: ADR certificates are valid for five years, before the end of which drivers must take a refresher course to remain compliant.

What is Dangerous Goods Awareness (DG) Training?

DG training is a broader category of hazardous materials training that applies to individuals involved in Road transport that may then involve other modes of transport (Multimodal). However, DG training is road specific with other transport mode information only.  This training ensures that personnel handling dangerous goods at any stage of the supply chain understand safety regulations and compliance requirements.

Who Needs DG Training?

DG training is required for:

  • Drivers transporting dangerous goods under certain limits.
  • Drivers carrying only Limited Quantities (New for 2025).
  • Warehouse staff handling dangerous goods.
  • Freight forwarders and logistics coordinators.
  • Shippers and consignment handlers.
  • Airline, maritime, or rail operators dealing with hazardous materials.
  • Packaging and labelling personnel involved in preparing dangerous goods for transport.

What Does DG Training Cover?

  • General awareness of dangerous goods regulations by road (ADR, CDG).
  • Basic awareness of other modal regulations (IATA, IMDG, RID, etc.).
  • Packaging, labelling, and documentation requirements.
  • Limited Quantity and Lithium Battery specialisations.
  • Handling and storage procedures for hazardous materials.
  • Risk assessment and emergency procedures.
  • Basic information on other regulations including sea (IMDG), air (IATA), and rail (RID).

Key Differences Between ADR and DG Training

ADR Training: Road transport of dangerous goods in tanks, bulk, and large-quantity packages.

DG Training: Road transport of dangerous goods in packages, with basic awareness of air, sea, and rail transport.

Who Needs It?

ADR Training: Drivers transporting dangerous goods above threshold limits.

DG Training: Drivers (under limits), logistics staff, warehouse workers, shippers, office-based compliance personnel

Regulatory Basis

ADR Training:ADR (Road), CDG (Road)

DG Training: Mainly ADR (Road), CDG (Road), plus basic IATA (Air), IMDG (Sea), RID (Rail)

Validity ADR Training:5 years (renewal required)

DG Training: Typically 2 years (varies by role and sector)

Course Focus

ADR Training: Driver safety, emergency response, safe loading/unloading

DG Training: Packaging, labelling, documentation, multimodal compliance

Which Training Do You Need?

  • If you are a driver transporting dangerous goods by road above certain threshold limits and vehicle types → You need ADR training.
  • If you are a driver carrying dangerous goods packages under certain threshold limits, work in logistics, shipping, or warehousing → You need DG training.
  • If your job involves packaging, documentation, or regulatory compliance → DG training is essential.

Conclusion

Both ADR and DG training are essential for ensuring the safe and legal transport of hazardous materials. ADR training is specific to road transport, while DG training applies to a wider range of industries and transport modes. Choosing the right certification is crucial for compliance, safety, and avoiding penalties.
