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?

The orange sign you've provided is a hazard sign indicating that the vehicle is transporting dangerous goods. In this case, when you see a liquid leaking from a vehicle with such a sign, the following actions are crucial:

1. Providing the number from the sign during an emergency call helps emergency services identify the specific type of hazardous material involved. This information is essential for appropriate response measures and safety protocols.

2. Avoiding the area into which the liquid has leaked is critical for your safety. Depending on the type of hazardous substance, it could pose health risks or lead to further accidents.

It's important to refrain from attempting to stop the leak because that could put you in danger, especially if you are not trained to handle hazardous materials. These actions align with German traffic laws regarding safety in dangerous situations involving vehicles transporting hazardous goods. Always prioritize your safety and the safety of others in such scenarios.
