430 ILCS 30/2
It is the finding of the General Assembly that hazardous materials are essential for various industrial, commercial and other purposes; that their transportation is a necessary incident to their use; and that such transportation is required for the employment and economic prosperity of the People of the State of Illinois.
It is therefore declared to be the policy of the General Assembly to improve the regulatory and enforcement authority of the Department of Transportation to protect the People of the State of Illinois against the risk to life and property inherent in the transportation of hazardous materials over highways by keeping such risk to a minimum consistent with technical feasibility and economic reasonableness.
It is not the intent of the General Assembly to regulate the movement of hazardous materials in such quantities that would not pose a substantial danger to the public health and safety, such as fuels, fertilizer and agricultural chemicals while being used in a normal farming operation or in transit to the farm.
