What measures must you take if you break down with a load which has to be transported hot (e.g. bitumen transport)?

You answered correctly. When your vehicle breaks down with a hot load like bitumen, you need to make sure other road users are not put in danger, which means securing the scene and your vehicle. You must also organize help, as quick assistance is especially important with such loads. Finally, it’s necessary to maintain the required temperature of your load to avoid damage or dangers from cooling down. All three actions are important to ensure safety for yourself, your cargo, and others on the road. This combination of steps is required by German traffic rules when dealing with hazardous or sensitive loads in breakdown situations.
