Utah police officers are trained to look for certain behaviors when it comes to determining when a driver is driving under the influence of either alcohol or drugs. The problem is that the existence of those behaviors does not always mean that an individual is impaired. Sadly, individuals are often arrested for DUI based on field sobriety tests and observations that are subjective and unreliable.
For example, a woman was recently taken into custody on suspicion of driving under the influence of a controlled substance. She came into contact with officers after being rear-ended in traffic. The officer believed that her erratic behavior was the result of being under the influence of a then unidentified substance. Field sobriety tests were conducted, and based on her failure of those tests, she was arrested.
