Do you need to stop before a railroad crossing if you are hauling Division 4.3 materials?

When hauling Division 4.3 materials, which are defined as substances that are wet (with water) and can spontaneously ignite or react when exposed to moisture, it is crucial to stop before a railroad crossing if your vehicle is placarded. This requirement is in place to ensure safety, as these materials can pose significant risks, including the potential for fire or hazardous reactions if not managed properly.

The need for placarding indicates that the load being transported is hazardous, which triggers the requirement to stop at railroad crossings. This procedure is intended to give the driver an opportunity to assess any potential train activity and ensure safe passage across the tracks. Compliance with these regulations is vital in preventing accidents and ensuring the safety of both the driver and the public.

In contrast, hauling hazardous materials without proper placarding does not invoke the same stopping requirement. Additionally, simply carrying hazardous waste does not change the fundamental necessity of placarding for certain materials, nor does the presence of a train alone dictate stopping if the hazardous materials require it. Each of these considerations emphasizes the importance of proper labeling and adherence to safety protocols when transporting hazardous materials.
