CHICAGO - State officials are warning drivers that Super Bowl Sunday can be one of the most deadly days of the year in Illinois when it comes to alcohol-related traffic deaths.

Last year, according to the Illinois Department of Transportation, four people were killed in crashes during Super Bowl weekend. Three of those crashes were alcohol-related.

Secretary of State Jesse White is reminding people to enjoy the weekend safely and use designated drivers if attending parties that include alcohol.

White says that means ``designating a sober driver, taking a cab or bus, or staying where you are.''
