“Wrong-way drivers” continue to be a Chicago-area traffic safety hazard, primarily on expressways and toll roads. As seen in the many accidents involving “wrong-way drivers” (many of which are summarized on this site in the “wrong-way drivers” category) many of these accidents result in one or more fatalities. Most of the drivers who are driving in the wrong direction are doing so while intoxicated on alcohol and/or drugs.
There have been many efforts made to reduce the number of these “wrong-way drivers.” Some of the efforts have included increased police enforcement, as well as placing large red signs on expressway ramps alerting drivers if they are driving in the wrong direction. Various technologies are also being investigated.
