To perform the test, the suspect will take nine heel-to-toe steps along a straight line during which time they must keep their arms to their side and count each step out loud. FSTs are primarily used in national states that require the police establish probable cause for arrest (reasonable grounds in Canada) as a prerequisite for requiring a chemical blood alcohol test. Currently, there are three tests which are used throughout the United States: the horizontal gaze nystagmus (HGN) test, the walk-and-turn test (WAT), and the one-leg stand test (OLS). Field sobriety tests are used to gauge a driver’s cognitive and physical functions to determine the driver’s level of impairment. 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.

They have published several training manuals associated with FSTs. Drivers who may have a difficult time passing a field sobriety test can include the elderly, the disabled, and those who are overweight. [14][15] It is likely that, if FSTs are being used, some equivalent to probable cause is necessary to sustain a conviction based on a demand for a chemical test. FSTs are requested in the police stop phase, and are used to provide tangible evidence sufficient to meet the requirements for probable cause for an arrest. FSTs (and SFSTs) are primarily used in the US, to meet "probable cause for arrest" requirements (or the equivalent), necessary to sustain an alcohol-impaired driving (DWI or DUI) conviction based on a chemical blood alcohol test. Through the performance of these tests or evaluations, the officer subjectively determines how the motorist reacts to and performs the requested tasks. The HST is characterized by the tester performing a visible activity, so the suspect is less likely to decline at that stage. STANDARDIZED FIELD SOBRIETY TEST BATTERY -A battery of tests, Horizontal Gaze Nystagmus, Walk-and-Turn, and One-Leg Stand, administered and evaluated in a standardized manner to obtain validated indicators of impairment based on NHTSA research. People who receive multiple DUI offenses are often people struggling with alcoholism or alcohol dependence. The Preliminary Alcohol Screening Test, PAS Test or PBT, (breathe into a "portable or preliminary breath tester", PAS Test or PBT). Alternative tests, which have not been "scientifically" validated by the NHTSA, include: There were three tests chosen to constitute the "Standardized Field Sobriety Tests", which are: Although most law enforcement agencies continue to use a variety of these FSTs, most use the three-test battery of validated field sobriety tests, referred to as the Standardized Field Sobriety Test (SFST). The US National Highway Traffic Safety Administration (NHTSA) began research in 1975 on how to test suspects for impaired driving. When an individual is pulled over for driving under the influence, the Standardized Sobriety Test is the first thing a police officer will ask you to perform before you are arrested. The Finger-to-Nose Test (tip head back, eyes closed, touch the tip of nose with tip of index finger).

The types of field sobriety tests conducted by U.S. laws enforcement agencies varied for many years, with different groups using a wide variety of tests to identify drivers who were under the influence of drugs and alcohol. One author alleges that FSD analysis reports do not meet scientific peer review standards: "The reports for all three studies issued by NHTSA are lacking much of the material and analysis expected in a scientific paper, and none have been published in peer-reviewed journals" (Rubenzer 2008;[28] Rubenzer 2011). Nevertheless, these tests are common in North America, because the primary purpose of FSTs is to establish probable cause to sustain an arrest and invoke the implied consent law. The officer then uses an instrument to measure an individual's blood-alcohol concentration (BAC), most commonly called a breathalyzer. [30], In the US, the legal procedure is police stop (Police stop requiring "reasonable suspicion" or another qualified reason for a police stop), probable cause, and arrest. Officers use field sobriety tests to determine whether to arrest you for DUI.

(must receive affirmative response). The proper instruction, according to the NHTSA Guidelines, is as follows: The other standardized test is the One Leg Stand (OLS).

Don’t let a field sobriety test stand in your way. [17] The NHTSA indicates that the non-standardized tests are either "not scientifically reliable",[17] with some assertions that SFSTs can be used to estimate 0.08% BAC. •Original research by Southern California Research Institute (SCRI) showed the test was 77% accurate at detecting a BAC of 0.10 or above. 1. [33] If the urine sample is positive, then the urine is sent for more testing to determine the exact drug taken (confirmation of being illegal or prescribed). [24][25] (National states without probable cause or "reasonable grounds" requirements are of course likely to be less restrictive on PBT/PAS requirements.). The test subject's arms must remain at their side. By 1981, officers in the United States began using the organization's battery of standardized sobriety tests to help make decisions about whether to arrest suspected impaired drivers. With alcohol, a drunk driver's level of intoxication is typically determined by a measurement of blood alcohol content or BAC; but this can also be expressed as a breath test measurement, often referred to as a BrAC.

According to the NHTSA, if the tests are conducted according to the specified requirements, the rate of identifying intoxicated drivers could be as high as 90%. The Preliminary Breath Test (PBT) or Preliminary Alcohol Screening test (PAS) is sometimes categorised as part of field sobriety testing, although it is not part of the series of performance tests.

[28] The NTSA used to say that those who are 50 pounds or more overweight may have difficulty performing the test, and that the suspect must walk along a real line. FSTs are generally regarded as a curiosity elsewhere. [citation needed], To determine impairment in countries such as Australia, a simple breath or urine test is often taken. [27] The fact that officers are no longer required to provide a line for the suspect to walk along may affect the outcome of the test, and often adds to the scrutiny received from critics.
