You are involved in an accident with another vehicle to which the following orange-coloured sign is attached. You see a liquid leaking from the vehicle. What is the right course of action?

This orange-coloured sign is a hazardous materials (hazmat) identification panel used in road transport. The upper number (33) is the hazard identification number indicating the type of danger, and the lower number (1203) is the UN number identifying the specific substance—in this case, 1203 refers to gasoline.

In case of an accident involving a vehicle with such a sign and you see a dangerous liquid leaking, it is crucial to:

- Provide the identification number from the orange sign (both numbers) when calling emergency services. This helps the responders quickly understand the exact nature of the danger and how to act safely and effectively.
- Avoid walking into or near the area where the liquid has leaked because it could be flammable, toxic, or otherwise dangerous.

Attempting to block the leak yourself is unsafe unless you are specially trained and equipped, so it is not recommended according to German traffic safety rules.

Remembering these points ensures safety and helps emergency responders manage hazardous materials incidents properly.
