AUSTIN (KXAN) -- A county in the Lone Star State ranked No. 1 for the highest percentage of fatal DUI-related crashes on Halloween, according to analysis from Florida-based personal injury law firm Anidjar & Levine. The lawyers' findings cited data from the National Highway Traffic Safety Administration between 2018 and 2022, with four Texas counties landing in the Top 20 counties for DUI-related fatal crashes nationally. Texas' Ellis County ranked No. 1, with 46.2% of drivers involved in fatal crashes during Halloween under the influence of alcohol, drugs or medication. That figure came from an analysis of 13 drivers involved in fatal crashes over the five-year period, with six of those found to be under the influence. Bastrop County in Central Texas came in at No. 4, with 38.5% of those fatal crashes during the October holiday involving drivers under the influence. Of 13 total drivers involved in fatal crashes during the reporting period, five were reportedly under the influence at the time of the crash.

"This leads to a higher likelihood of individuals driving under the influence." Here in the Austin area, the Austin Police Department has previously enacted its "No Refusal Initiative" during the Halloween season. That department effort allows APD to obtain a blood search warrant during specific hours "when an arrested driver refuses to submit to a blood alcohol test," APD officials said. Earlier this month, the department announced it would be pivoting to a year-round effort, instead of only during specific timespans like holiday weekends.
