After turning off of Runway 34R on a high speed exit at a speed of approximately 10 KTS; I lost directional control of the aircraft. The aircraft exited the taxiway on the right side across a grass area and came to a stop on an adjacent runway exit. A taxiway light was damaged but there was no damage to the aircraft or injuries. Airport operations advised me after the fact that there had been freezing rain for several hours that had later been covered by snow. Even on the taxi-in at speeds as low as three knots there were areas where the aircraft was difficult to stop. In the future I will come to an almost complete stop in these conditions before making any turns and try to utilize only 90 degree runway turnoffs. Even at such a low speed there can be issues with directional control of the aircraft after heavy snow and ice events.
