When hauling chlorine, stopping before crossing a railroad grade is imperative for safety, and it is required when carrying any amount of the hazardous material. This regulation is in place due to chlorine being a toxic gas that can pose serious risks to public health and safety in the event of a spill or accident.

The requirement to stop regardless of the amount being transported is crucial because even small quantities of chlorine can be dangerous if released into the environment. Given its hazardous nature, stopping ensures that the driver has a clear view of the tracks in both directions and can ensure that no trains are approaching. This precaution is in alignment with emergency response protocols and helps prevent potential accidents that could have devastating effects.

Other options may seem relevant, but they do not encompass the thorough safety measures necessary when transporting hazardous materials like chlorine. This principle protects not just the driver and vehicle but also the general public and the environment from potential harm.
