An imminent icing condition detector employs an infrared sensor with a focusing element to receive ambient infrared energy from a surface, particularly a road surface, and the output of the sensor is processed to provide an indication of the likelihood of icing conditions and to accordingly control a traction control substance deployment system, such as a truck that dispenses a de-icing, anti-icing, or traction substance, such as sand, salt, or other material or mixture of materials in solid granular, liquid, or mixed form.
