Deer mirrors were placed in 12 random 0.5-mile test sections along 14.8 miles of I-95 between Topsham and Gardiner, Maine, to test the effectiveness of the mirrors in reducing deer-vehicle collisions. In nearly 4 years, 11 deer-vehicle collisions were reported. Of these, 4 were on the mirrored sections, 2 were on the non-mirrored sections, and the remainder were on off-ramps or at unknown locations. There was no evidence to support the claim that mirrors were effective. A review of other studies reveals a lack of data to support the effectiveness of mirrors. The data available indicates mirrors and reflectors are ineffective deterrents to deer-vehicle collisions.
