Transport of Dangerous Goods by Road in 2026
The transport of dangerous goods by road accounts for approximately 4% of the total volume transported in Spain and across the European Union. Although relatively small in percentage terms, its impact on sectors such as the chemical industry, energy and automotive is strategic.
In 2026, increased inspections and regulatory updates raise the level of requirements for operators and consignors.
Regulatory framework: ADR
Transport is governed by the ADR, which classifies dangerous goods into nine classes according to their level of risk: gases, flammable liquids, corrosive substances, explosives, among others.
Recent updates align inspection criteria with Directive (EU) 2025/1801, strengthening roadside enforcement and prioritising actual risk over purely formal non-compliance.
Key requirements in 2026
– Drivers holding a valid ADR certificate
– Certified vehicles and tanks
– Properly completed consignment note
– Mandatory written instructions
– Appointment of a safety adviser where required
– Correct marking and labelling
Failure to comply may result in financial penalties and even vehicle immobilisation.
Classification of dangerous goods:
Class 1 – Explosives
Substances and articles with an explosion risk (pyrotechnics, ammunition, industrial explosives).
Class 2 – Gases
Compressed, liquefied or dissolved gases (flammable, non-flammable or toxic).
Class 3 – Flammable liquids
Liquid substances with a low flash point (fuels, solvents).
Class 4 – Flammable solids
Includes substances that may ignite easily, undergo spontaneous combustion, or react with water.
Class 5 – Oxidising substances and organic peroxides
Materials that promote combustion or present high chemical instability.
Class 6 – Toxic and infectious substances
Products that may cause serious harm to health or transmit diseases.
Class 7 – Radioactive material
Substances that emit ionising radiation.
Class 8 – Corrosive substances
Materials that can damage living tissue or other materials (acids, bases).
Class 9 – Miscellaneous dangerous substances and articles
Substances presenting risks not covered by the previous classes (e.g. lithium batteries).
Incorrect classification leads to errors in labelling, documentation and transport conditions.
Operational risk management
In 2026, the transport of dangerous goods can no longer be approached as a standard logistics service. Document traceability, prior review of UN codes and technical verification of each shipment are essential to prevent penalties or incidents.
Responsibility is shared between the consignor and the carrier.
The transport of dangerous goods by road requires specialisation, continuous regulatory updates and rigorous operational control. In an increasingly demanding regulatory environment, prevention and proper document management are key to ensuring industrial continuity and safety.
