Deer Crossing Signs

Research has shown that the installation of static deer crossing signs has not been effective in reducing the number of deer-vehicle collisions. Due to the ineffectiveness of these signs, it is the City of Flagstaff’s policy that static deer crossing signs will no longer be installed.

Warning signs can be useful to inform drivers of approaching conditions, however, deer crossings are infrequent which leads to disregard of the signs and driver behavior is no longer impacted.

Minnesota Department of Transportation (MnDOT) has researched and reached the same conclusion and has not installed static deer crossing signs since 2005 and has started taking down these signs when they reach the end of their lifespan. The number of deer-vehicle collisions has not been affected.
