Officials with the state Department of Public Safety are advising Iowans not to push their luck by over-indulging with alcohol during Monday’s day-long celebration. The Iowa Governor’s Traffic Safety Bureau is reminding Iowans to celebrate responsibly and to designate a sober driver before the party begins. In recent years, two of every five traffic deaths that occurred on the St. Patrick’s Day holiday involved a drunk driver, officials said. In Iowa, eight people lost their lives last March in alcohol-related traffic crashes with a double fatality during the St. Patrick’s Day weekend, state officials say. Iowa law enforcement will step up patrols this holiday weekend to prevent alcohol-related crashes. Also, public safety officials note that drunken-driving violators often face jail time, loss of driving privileges, higher insurance rates and other expenses including attorney fees, court costs, vehicle towing or repairs, and lost wages due to time off from work. An average OWI conviction can cost close to $10,000. “A phone call or taxi is a less costly and a safer alternative. Don’t push your luck this St. Patrick’s Day. Celebrate smart and stay safe,” according to a DPS news release.
