Under what circumstances is placarding required when transporting pesticides?

Placarding is required when transporting pesticides in containers larger than 119 gallons due to safety regulations aimed at informing others of potential hazards. This requirement helps emergency responders and the general public identify vehicles carrying large quantities of hazardous materials. By using placards, those in proximity to the transport vehicle can take appropriate precautions, especially in case of an accident or spill.

Transporting pesticides in containers larger than 119 gallons poses a greater risk due to the volume and potential for significant harm if a leak or spill occurs. The regulations surrounding this requirement are set forth by the Department of Transportation (DOT) and are part of a larger framework meant to ensure public safety.

Smaller containers, such as those packaged in cardboard or those less than 119 gallons, do not require placarding since the risk is considered to be lower. Similarly, placarding is not required only during night transportation or whenever pesticides are transported; it specifically pertains to the volume of the containers being transported.
