Snowplow simulator offers rare chance to practice - Article Photos 6/6

A screen shows a collision during a North Texas Tollway Authority training class in Plano, Texas, Thursday, Nov. 15, 2012. The NTTA is using the computer generated simulator to help snowplow operators become better at handling slick roads in a region not used to ice and snow. Highway officials in at least nine states are using the sophisticated simulator to give plow drivers a chance to practice snow removal in any weather. It works like a video game, recreating slick pavement, poor visibility and even children or animals bolting across the road.(AP Photo/LM Otero)
