Holidays are regarded as some of the happiest days of the year, with time made for family and friends. And of course, holidays have also procured another reputation as well: as days designed for heavy drinking. Of all the holidays, St. Patrick's is one of the most infamous for high levels of intoxication, with thousands of people throughout the U.S. being brought into emergency rooms and detox centers for alcohol poisoning. But what's most dangerous, perhaps, is when those who have been drinking get behind the wheel of a car. In 2013, there were nine fatal accidents on St. Patrick's Day, which fell on a Sunday, and an additional 38 over the preceding weekend in the state of Texas. In response, Harris County patrol officers prepared heavily for DWI drivers this St. Patty's Day, implementing a "no-refusal" policy.
