This case involves a diabetic man who drove himself to a bar for an event with a group of his coworkers. The man claimed only to have had 3 drinks while at the event. Around 11:30 pm, the man left the event and drove home. While on the highway, he was pulled over for speeding. According to the officer who pulled him over, the man was driving at 85 mph in a 55 mph zone. The man was given a breathalyzer test which came back with a reading of .20 and was charged with driving while intoxicated. The man claimed that his diabetes contributed to an unfairly high breathalyzer reading. An expert in pharmaceutical toxicology was sought to discuss the extent to which the man’s diabetes and ketoacidosis could have affected the breathalyzer results.
