We disclose adaptive active safety systems which utilize a sensing system (201) to detect road conditions and actuate an active safety routine based thereon. One disclosed method includes transmitting, with a multispectral LIDAR system on a vehicle (221), a multispectral light beam directed at an anticipated region of travel (271) of the vehicle within a road, and analyzing a response, of a photodetector, to a return of the multispectral light beam. The method also includes determining, based on the analyzing of the response, a hazardous surface condition in the anticipated region of travel (271) of the vehicle (221), and actuating, based on the determination of the hazardous surface condition, an active safety routine. The method can be executed by an Advanced Driver Assistance System (ADAS) in which the determinations of the hazardous surface conditions on the road in the anticipated region of travel (271) are executed in real time to thereby produce a road aware ADAS. The sensing system (201) of vehicle (221) is scanning a scanned region (270). The sensing system can extract a portion of said scanned region 270 corresponding to the anticipated region of travel (271) of vehicle (221). The sensing system is also scanning a potential encountering object (222) and can provide distance information (260) to the ADAS system. The sensing system can detect that the road is wet or dry, that it includes snow, ice, oil, gravel, etc. and determine a grip of the road and an optimum following distance based thereon.
