A method of inspecting a road for substances includes generating a flash of infra-red light at a wavelength to illuminate a portion of the road. The wavelength corresponds to an absorption wavelength of a substance to be detected. The method further includes, in response to a difference in backscatter intensity of an image of the portion captured during the flash and an image of the portion captured before or after the flash being greater than a threshold amount, outputting a signal indicating presence of the substance on the portion.
