As part of Work Zone Safety Week, police in Illinois went undercover as construction workers. The goal was to increase awareness of the dangers that speeding and distracted driving can pose to people in work zones. They also cited drivers who were speeding or otherwise violating traffic laws. One officer who was monitoring traffic on Interstate 74 said that he cited nine drivers in a matter of minutes for speeding.
People in Illinois who are on a low-carb diet that has put them into ketosis or who suffer from such conditions as acid reflux or diabetes could cause some types of breath tests for blood alcohol content to give inaccurate results. In Texas, an attorney got DUI charges dropped against a man who was in ketosis but who did not appear to be drunk during field sobriety tests. However, when he took a breath test, the device registered his blood alcohol content above the legal limit.
