When Florida law enforcement officers pull people over on suspicion of driving under the influence of drugs or alcohol, they may administer a roadside test in order to determine whether the driver is actually drugged or drunk. If the readings of these roadside tests show that the motorist is indeed driving under the influence, the driver may be arrested and charged with a crime. According to the New York Times, at least 1.2 million people in the U.S. are arrested for the illegal possession of drugs each year. However, law officers are not chemical scientists, and may make mistakes when conducting roadside drug tests. Multiple studies also indicate that roadside drug tests often provide unreliable results and could lead to the wrongful charge and conviction of an innocent person.
