Most dangerous goods compliance is about preventing accidents. A harder-edged layer exists for the loads someone might want on purpose: the explosives, toxic gases, radioactive sources and other high-consequence goods whose misuse is the point. The government publishes security requirements for moving dangerous goods by road and rail, together with driver security advice, and the obligations sit on top of the ADR safety framework as a separate discipline - one where the threat is not the load failing, but the load being taken.
The ADR system’s accident logic assumes nobody wants the incident to happen. Security logic assumes someone might. High-consequence dangerous goods - the ADR definition covers the materials whose deliberate release or theft could do mass harm - therefore attract duties beyond the safety ones: the consignor, carrier and consignee share a security obligation that runs from planning to delivery. The government’s security requirements document sets the framework: which goods count as high-consequence, what a security plan must address, and the security awareness training that everyone in the chain must have.
The security plan is the centrepiece. For businesses carrying high-consequence goods, the requirement is a documented plan covering how the security risk is managed: how personnel are vetted and trained, how vehicles and loads are secured, how routes and schedules are protected, and what happens when something goes wrong. It is a living document - reviewed, tested, and adjusted to the threat level - not a one-off file created for an audit.
The driver security advice translates the system into cab-level practice, and its themes will be familiar to anyone who has done high-value work, tightened for the dangerous goods context. Protect the information: who knows what is being carried, on which route, at what time - the fewer people with the full picture, the smaller the attack surface, and casual talk about loads and routes is a security leak with a social life. Protect the vehicle: locked, alarmed where fitted, never left unattended and unlocked, and parked deliberately - secure sites, lit areas, never an opportunistic lay-by with a high-consequence load aboard. Protect the journey: route planning that avoids predictable patterns where the risk justifies it, and the discipline about what to do when something feels wrong - the vehicle following too long, the staged incident, the unexpected “official” stop.
That last point deserves its weight. Theft of dangerous loads often involves deception - bogus officials, engineered breakdowns, feigned accidents - and the driver’s training has to cover the difference between a genuine emergency stop and a trap: verify before you comply, communicate before you open up, and keep the vehicle’s security intact until identity is certain.
Security awareness training is not optional culture; it is a requirement for everyone whose duties involve high-consequence dangerous goods - drivers, planners, warehouse staff, management. The training covers the threat, the security plan’s contents as they affect each role, and the recognition-and-response behaviours the plan depends on. Like ADR training it needs refreshing, and like all training it only exists, in the eyes of an auditor, when it is recorded. The dangerous goods safety adviser’s orbit naturally extends here: the DGSA’s monitoring role and the security plan’s disciplines interlock, and businesses that run them as one system find both work better.
Security duties feel like pure cost until the market reality is examined. The customers who ship high-consequence goods - chemical manufacturers, defence suppliers, nuclear licensees - buy security as much as transport: their own regulator-facing obligations make carrier security a selection criterion, audited with the same seriousness as safety compliance. A carrier whose security plan, training records and driver discipline survive those audits is in a small pool; a carrier without them is not in the market at all.
The broader lesson generalises: even outside the high-consequence list, dangerous goods attract attention from thieves in ways general freight does not, and the security habits the formal regime teaches - information discipline, vehicle discipline, journey discipline - are worth more than their compliance value on any sensitive load. The load that is a target is protected by exactly the same routines as the load that is merely valuable. The regulations only differ on which loads make the routines mandatory.
Underneath the formal requirements sits a judgement every operator in this space makes daily: what counts as suspicious. The guidance trains toward reporting - the unfamiliar vehicle loitering near a loaded trailer, the caller asking oddly specific questions about schedules, the route survey that looks like tourism but is not - and the fleets that handle security well are the ones where reporting costs the reporter nothing. A driver who raises a false alarm and is thanked stays alert; one who is mocked for it goes quiet, and quiet is what the people watching the load are counting on. Security culture is built one unremarkable report at a time.
