Sobriety Test Law and Legal Definition

Sobriety test is a method of testing whether a person is intoxicated or not. Sobriety tests can include coordination tests and/or mechanical devices that measure blood-alcohol content of a person's breath or blood sample. A field sobriety test is a motor-skills test administered by an officer during a stop to determine whether a suspect was driving while intoxicated; the test usually involves checking the suspect's speaking ability or coordination by reciting sections of the alphabet or walking in a straight line.
