LAWRENCEBURG, Ind. (WKRC) – Happy hour is back in Indiana after 40 years. A House bill has been signed into law allowing bars and restaurants to offer hourly drink deals. Happy hour was banned to reduce drunk driving, but the bill’s author said research doesn’t show a correlation. Happy hour must be cut off by 9 p.m. and can’t be offered more than four hours per day. Bars and restaurants also aren’t allowed to offer drinking games or two-for-one specials.
