"In an independent expert's analysis of five years of data on a segment of Interstate 10 between Phoenix and Tucson, 91 total drivers in incidents were able to stop or recover within the median, avoiding a collision and without striking a barrier or other hazard. The wide I-10 medians – 81 feet wide at the location of the crash in this most recent case – provide drivers with a safety buffer to come to a safe stop. When median barriers are installed, the opportunity for a safe stop is eliminated and the state would be sued for not maintaining nationally accepted median widths if a crash were to occur involving the median barrier."
