WORLAND, Wyo. (AP) — The Wyoming Department of Transportation is using reflector poles in several areas in the state to see if they help prevent wildlife/vehicle collisions.

WYDOT spokesman Cody Beers tells the Northern Wyoming Daily News (http://bit.ly/zKMCNc ) the goal is to determine if the reflectors are instrumental in keeping deer off the highway and to figure out if there’s a pattern to the animal crossings. The poles are sometimes covered to see how the deer react to not having the reflections of the headlights, and the display is switched each month.
