<P>PROBLEM TO BE SOLVED: To provide a road surface condition discrimination apparatus for accurately discriminating a road surface condition. Ž<P>SOLUTION: The road surface condition discrimination apparatus includes: a laser measurement apparatus for irradiating one point or a linear route on a road surface with a laser light, and measuring a reflection light from the road surface; a temperature measurement apparatus for measuring a road surface temperature; and a discrimination apparatus for discriminating the road surface condition based on a statistical process result obtained by applying a predetermined statistical process to a measurement result from the laser measurement apparatus and the road surface temperature. The discrimination apparatus selectively switches a first road surface discrimination mode for discriminating the road surface condition including a dry condition if snow is melted on the road surface and a second road surface discrimination mode for discriminating the road surface condition excluding the dry state if snow is accumulated in response to a discrimination result of the road surface condition.
