Missing ADR papers? From June, your truck could be stopped

The rules were published in October 2025. Member states have until 23 June 2026 to implement them, with enforcement starting on 24 June 2026. The aim is to harmonise ADR inspections and reduce differences in interpretation between countries.

Single checklist for roadside inspections across the EU

The most significant operational change is the introduction of a single EU inspection checklist to be used by national enforcement bodies during roadside checks.

The checklist covers, among other areas:

• whether vehicles, tanks and containers meet ADR requirements,
• whether approvals are present and valid,
• the accuracy and completeness of transport documentation,
• the safety equipment carried on board.

Each checkpoint is linked to specific ADR provisions. The intention is to make enforcement more consistent across the EU, particularly for operators working across multiple jurisdictions.

Three risk levels — the most serious can trigger immobilisation

Delegated Directive (EU) 2025/1801 also introduces a three-tier, risk-based classification of infringements.

Category I — highest risk

Category I covers breaches that create a serious risk of death, serious injury or major environmental damage. During a roadside inspection, these can trigger immediate measures, including immobilisation of the vehicle.

Examples include:

• leakage of dangerous substances,
• transport without required documentation,
• no valid ADR driver training certificate,
• missing vehicle markings,
• dangerous goods carried in unapproved packaging or tanks,
• no appointed ADR safety adviser where one is required.

Category II — non-compliance requiring prompt correction

Category II covers non-compliance that can still lead to injury or environmental harm and should be corrected without delay.

Typical examples include:

• faulty fire extinguishers,
• missing mandatory safety equipment,
• damaged packaging,
• tanks or containers not properly closed,
• incorrect markings,
• missing ADR written instructions,
• irregularities in training for staff involved in transport operations.

Category III — formal non-compliance

Category III covers issues with limited safety impact that can typically be addressed after the inspection.

Examples include:

• plates and labels that do not meet required dimensions,
• missing elements in transport documentation,
• a driver with a valid ADR certificate who cannot present it during the check,
• a crew member missing an identity document,
• late presentation of required documents to inspectors.

Accountability across the logistics chain

The directive sets out obligations for each party involved in a dangerous-goods transport operation. Compliance with ADR is not treated solely as the carrier’s responsibility; it also applies to:

• the consignor,
• the consignee,
• the loader,
• the packer,
• the filler,
• the tank operator,
• the unloader.

The intention is to reduce uncertainty over liability and enable inspectors to identify which party is responsible for a specific breach.

ADR documents must be readily available

Under the new approach, mandatory ADR documents must be kept in the cab and be available for immediate presentation during a roadside inspection. This includes, among other documents:

• training certificates,
• vehicle approval certificates,
• ADR written instructions.

Digital documentation is acceptable only where it can be presented promptly and in line with ADR requirements.

If required documents are missing or incorrect, the vehicle may be immobilised and the parties involved may face administrative or criminal penalties.

What companies should check before 24 June 2026

With the enforcement date approaching, operators should verify that internal procedures align with the new inspection framework. In practice, this may include:

• updating documentation sets and operating instructions,
• checking the validity of ADR certificates for drivers and relevant staff,
• confirming whether the goods carried fall under the applicable classifications and thresholds,
• reviewing whether an ADR safety adviser must be appointed under the relevant thresholds and exemptions.

From 24 June 2026, roadside ADR inspections across the EU are expected to follow the same checklist and risk criteria. For transport and logistics operators, documentation readiness and certificate validity will be central to avoiding disruption during checks.
