Justipedia explains Urine Test
A urine test can be employed at the request of the police or through a warrant for the purpose of determining if a person was under the influence of either drugs or alcohol, or both, at any specific time. This is often done when an accident occurs or when a person has been pulled over for drinking and driving and refuses to submit to a breathalyzer. They are commonly employed as a tool of probation and allow parole officers to monitor whether a person has committed an offense while on parole or probation. Drug and rehabilitation service centers routinely use urine tests to determine what substances their clients are on.
