WINONA, Minn. – A Winona driver, Daniel Gardner Arndt, 32, showed 0.15% blood-alcohol content after a traffic stop — almost double the threshold for impairment. This was about 1:03 a.m. at Fourth and Center streets near the downtown bar district. The arrest was without incident. The stop was for a bad taillight. Police said Arndt had slurred speech, bloodshot and watery eyes, and strong odor of alcohol. Arndt said his last drink was an hour earlier.
