A recent study from Joshua Madsen and Jonathan D. Hall outlines how dynamic message signs (DMSs) displaying the year-to-date number of fatalities actually distract drivers and cause more accidents. After analyzing data on 880 fatality signs and all crashes occurring in Texas from 2010 through 2017, Madsen and Hall found that the number of crashes increased as drivers got closer to the signs. The number of crashes increased by 1.35% within 10 kilometers of the signs and raised to 1.52% within five kilometers of the signs. Those numbers only increased in areas with complicated road segments.
