If a police force does not have these testing devices, a more complicated routine is necessary. Upon suspicion that the driver has consumed alcohol, due to the officer noting the smell of alcohol, slurred speech, or other signs, the stopped driver is required to exit the vehicle and asked to take a series of roadside field sobriety tests (FSTs or SFSTs). These tests help the officer to determine whether the person's physical and/or mental skills are impaired. If the officer determines based on his/her observations during the tests that the driver is impaired and has

to arrest the person for suspicion of driving under the influence, the arrestee will be asked to take an alcohol breath test or a blood test. It is important to note that the driver cannot "pass" or "fail" a field sobriety test as they are not "pass-or-fail", they are only meant to aid the officer in determining if a suspect is impaired based on observations of the subject's performance on these tests. There are various guidelines are presented by the various states (US) as well as International rules for these type Sobriety Checkpoints or DUI.

Australia

In Australia, drivers may be stopped at any point along any public road by a police officer for what police term a "random breath test", commonly referred to as an "RBT". For an operation involving a large number of police (typically 10–20) at a fixed location, the colloquial term "booze bus" is often used. In July 1976, legislation allowing Random Breath Testing (RBT) came into force in the State of Victoria, with this being the first State in Australia to introduce such.

Drivers who are found to have a preliminary reading of equal to or greater than 0.05% are usually arrested and taken to the police station or RBT/"booze bus" to undertake a breath analysis. The machine used to perform a breath analysis is more sophisticated than the portable device that is used to administer a roadside RBT with the results of a breath analysis being used as evidence in court to prove a drunk driving charge. In all states and territories the concept has been extended to make sobriety checkpoints also use "Random Drug Test (RDT) buses" (or "dual buses"), capable of testing drivers for a number of illicit drugs including

At a sobriety checkpoint, drivers are necessarily stopped without

(BAC) over a set limit is defined as the crime; it is not necessary to drive recklessly or cause an accident in order to be convicted (although an impaired driver who also drives recklessly could face additional charges). To determine BAC accurately, it is generally necessary for the driver to subject himself to tests that are self incriminating, and drivers sometimes exercise their right against self incrimination to refuse these tests. To discourage this, some jurisdictions set the legal penalties for refusing a BAC test to equal or worse than those for failing a BAC test. In other jurisdictions, the legal system may consider refusing the roadside alcohol breath test to be probable cause, allowing police to arrest the driver and conduct an involuntary BAC test. The

found properly conducted sobriety checkpoints to be constitutional. In the majority opinion, Chief Justice Rehnquist wrote, "In sum, the balance of the State's interest in preventing drunken driving, the extent to which this system can reasonably be said to advance that interest, and the degree of intrusion upon individual motorists who are briefly stopped, weighs in favor of the state program.

, indicate that the net effect of sobriety checkpoints on traffic safety is infinitesimal and possibly negative." Justice Brennan's dissenting opinion argued that the police had failed to show that the checkpoint seizures were a necessary tool and worth the intrusion on individual privacy. "That stopping every car might make it easier to prevent drunken driving...is an insufficient justification for abandoning the requirement of individualized suspicion," he stated. Jurisdictions that allow sobriety checkpoints often carve out specific exceptions to their normal civil protections, in order to allow sobriety checkpoints. Although the U.S. Supreme Court has found sobriety checkpoints to be constitutionally permissible, ten states (

'', "Because the checkpoint program's primary purpose is indistinguishable from the general interest in crime control, the checkpoints violate the Fourth Amendment." This prohibits checkpoints erected to interdict narcotics or detect evidence of other illegal activities. However, this does not prevent police departments from attempting these types of checkpoints because they can be a significant source of revenue, particularly near festival periods like college spring break. Many individuals that are apprehended for possession of narcotics at these checkpoints are unlikely to be fully prosecuted on those charges, but the police will collect all fees associated with the arrest before reducing the charges or dismissing them altogether. Because of some inconsistencies between the laws and actual police practice, some individuals maintain that DUI checkpoints are violation of civil rights under the Constitution. Such checkpoints have been the subject of protests, such as individuals holding signs warning drivers "Police ahead, turn now."


Legal guidelines

In approving "properly conducted" checkpoints, Chief Justice Rehnquist implicitly acknowledged that there must be guidelines in order to avoid having these checkpoints becoming overly intrusive. In other words, checkpoints cannot simply be set up when, where and how police officers choose. As often happens in Supreme Court decisions, however, the Chief Justice left it to the states to determine what those minimal safeguards must be, presumably to be reviewed by the courts on a case-by-case basis. To provide standards for use by the states, the
National Highway Traffic Safety Administration The National Highway Traffic Safety Administration (NHTSA ) is an agency of the U.S. federal government, part of the Department of Transportation. It describes its mission as "Save lives, prevent injuries, reduce vehicle-related crashes" rela ...
subsequently issued a report that reviewed recommended checkpoint procedures in keeping with federal and state legal decisions. An additional source of guidelines can be found in an earlier decision by the California Supreme Court, ''Ingersoll v. Palmer'' (1987) 43 Cal.3d 1321, wherein the California State Supreme Court set forth what it felt to be necessary standards in planning and administering a sobriety checkpoint. The ''Ingersoll'' guidelines fall under the following general headings: # Decision making at the supervisory level # Limits on discretion of field officers # Maintenance of safety conditions # Reasonable location # Time and duration # Indicia of official nature of roadblock # Length and nature of detention # Advance publicity The U.S. Supreme Court's decision of '' Michigan Dep’t of State Police v. Sitz'' (1990) 496 U.S. 444, was decided after ''Ingersoll''. The U.S. Supreme Court did not criticize any of the ''Ingersoll'' guidelines, nor did it recommend any others; seemingly making it the law of the land and leaving the decision of whether to permit sobriety checkpoints to the individual states. In ''People v. Banks'' (1993) 6 Cal.4th 926, which was decided after ''Ingersoll'' and ''Sitz'', and incorporated a discussion of both cases in the opinion, the California State Supreme Court held that ''advance publicity'' is not an essential element of the constitutionally of a valid drunk driving roadblock. The Court concluded that although advance publicity remains a factor to consider, the lack of it alone does not render the roadblock unconstitutional. ''People v. Banks'' (1993) 6 Cal.4th 926. The following considerations expand upon the general headings listed above: *Decision making must be at a supervisory level, rather than by officers in the field. *A neutral formula must be used to select vehicles to be stopped, such as every vehicle or every third vehicle, rather than leaving it up to the officer in the field. *Primary consideration must be given to public and officer safety. *The site should be selected by policy-making officials, based upon areas having a high incidence of drunk driving. *Limitations on when the checkpoint is to be conducted and for how long, bearing in mind both effectiveness and intrusiveness. *Warning lights and signs should be clearly visible. *Length of detention of motorists should be minimized. *Advance publicity is necessary to reduce the intrusiveness of the checkpoint and increase its deterrent effect.


Effectiveness

There is a dearth of research regarding the deterrent effect of checkpoints. The only formally documented research regarding deterrence is a survey of Maryland's "Checkpoint Strikeforce" program.
