Half warning signs are an important part of dangerous goods labeling and offer a flexible and cost-effective solution for the transport of dangerous goods. But when exactly are they useful and what advantages do they offer compared to fully printed placards? In this article, we shed light on the possible uses of half warning signs and show why they can be a useful addition to dangerous goods management.
What are half warning signs?
Half warning signs are orange-colored dangerous goods labels measuring 120×300 mm, which are used in accordance with the regulations of the ADR (European Agreement concerning the International Carriage of Dangerous Goods by Road). They are used when only a UN number needs to be displayed. This is often the case with tank transports or when flexible labeling is required.
When does it make sense to use half warning signs?
Many companies rely on individually printed placards that contain all the necessary information. Nevertheless, there are some scenarios in which half warning signs offer considerable advantages:
Flexibility in hazardous goods labeling: Shippers often do not know in advance which UN numbers will be transported. With half warning signs, it is still possible to adapt the labeling at short notice.c
Cost efficiency: Existing dangerous goods labels or placards can be reused and supplemented with half warning signs instead of ordering completely new placards each time.
Sustainability: Reusing existing labels reduces waste and conserves resources.
Compliance with legal regulations: Half warning signs comply with current ADR regulations, ensuring safe and compliant hazardous goods labeling.
Legal basis for half warning signs
The use of half warning signs is regulated in Chapter 5.3 of the ADR. It stipulates that vehicles transporting dangerous goods must be fitted with orange warning signs. In certain cases, however, the display of the UN number is sufficient, which is why the half warning sign can be used as a legally compliant solution.
When is a half warning sign (120x300 mm) used?
According to ADR regulations, a half warning sign is used in the following situations in particular:
Tank vehicles: If a vehicle transports several compartments with different substances, each compartment can be provided with a separate UN number.
Changing loads: For transports where the load hazard numbers change, the half warning sign enables flexible adaptation.
Container and vehicle combinations: In some cases, half warning signs can be used in combination with standardized placards to meet specific requirements.
Dangerous goods with varying UN numbers: Shippers who transport different dangerous goods benefit from the option of adapting half warning signs at short notice.

Labeling errors: an often underestimated risk
Many retailers underestimate the importance of correct labeling. Frequent problems arise due to:
- Missing labeling: this is a clear violation of legal regulations.
- Incorrect label formats or layouts: Labels that do not comply with the applicable standards (e.g. incorrect size, unacceptable colors or symbols) can also be objected to. Incorrect labeling will be legally assessed in the same way as a complete lack of labeling.
- Illegible or damaged labels: These can also be deemed unacceptable and result in the dangerous goods not being allowed to be transported.
Consequences of violations
- Fines: These are incurred not only for missing, but also for incorrect labeling.
- Legal liability: Incorrect labeling can lead to accidents for which the retailer is held liable.
- Loss of image: Such errors can cause lasting damage to customer confidence.
