A chartered bus taking skiers home to Arizona ran off a curvy road and rolled down an embankment in a crash that split open the vehicle's roof and threw some passengers 100 yards. Eight were killed and 20 others injured. The Arrow Stage Lines bus was southbound on State Route 163 when it failed to negotiate a curve Sunday night, went off the road and rolled over several times down the 41-foot (12.5-meter) slope, said Trooper Cameron Roden of the Utah Highway Patrol. Although the road was described as wet from light rain, weather was not the "main factor," Roden said. "The main thing we're looking at is the driver failed to negotiate the turn." The highway is known as a challenge for drivers.
