Two lighted, animated deer crossing signs were installed adjacent to State Highway 82 south of Glenwood Springs, Colorado, delineating a 1.61km (1-mile) segment of highway where deer-vehicle accidents frequently occurred. Crossings per kill ratios were nearly identical with the signs off (56.5:1) and with the signs on (56.9:1). When the motorist was presented with evidence that a danger existed (i.e., deer carcasses in emergency lane), the response was much greater than when they were merely warned (via the deer crossing sign) of a potential danger. With evidence of danger, the response was the same regardless of whether or not the warning signs were on. Motorists' response in the form of speed reduction and/or increased awareness was not sufficient to affect the crossings per kill ratio. Since these lighted, animated signs were not effective in reducing the number of deer-vehicle accidents, it seems reasonable to assume that conventional deer crossing signs are not effective either. However, in areas where deer-vehicle accidents are especially numerous, warning signs may be useful for public relations and liability reasons.
