How many warning devices must be displayed for a vehicle disabled while carrying flammable liquids?

When a vehicle is disabled while transporting flammable liquids, it is required to display three warning devices to ensure safety and alert other drivers. These devices are crucial for preventing accidents and mitigating risks associated with the presence of hazardous materials on the roadway. The use of three warning devices is a standard safety measure that provides adequate visibility from different directions, effectively warning approaching vehicles of potential hazards.

In scenarios involving flammable substances, ensuring that other road users are adequately informed about the situation is critical. This requirement is aimed at enhancing the safety of the area surrounding the disabled vehicle and protecting both the driver and other motorists. Thus, adhering to this guideline is vital for compliance with safety regulations regarding the transportation of hazardous materials.
