Legal Requirements of Roadblocks: The Ingersoll/Palmer factors
Legal Requirements of Roadblocks:
The Ingersoll/Palmer factors
The Supreme Court of California rendered a decision on the premiere California roadblock case, Ingersoll v. Palmer, in 1987. This decision set the standard for how law enforcement agencies must conduct roadblocks, otherwise known as sobriety checkpoints. The Supreme Court identified a number of factors for minimizing the intrusiveness on the individual while balancing the needs of society in keeping drunk drivers off the road:
1) Decisionmaking at the Supervisory Level:
Only supervisory law enforcement personnel, and not officers in the field, may make the decision to establish a sobriety checkpoint and select the site. This requirement is important to reduce the potential for arbitrary and random enforcement.
2) Limits on the Discretion of Field Officers:
A neutral mathematical formula, such as every driver, or every third, fifth, or tenth driver should be used in determining who to stop at the roadblock. This requirement takes away the discretion of the individual officer to stop any driver he/she chooses without any legitimate basis.
3) Maintenance of Safety Conditions:
Primary consideration must be given to maintaining safety for motorists and officers. In order to minimize the risk of danger to motorists and police, proper lighting, warning signs and signals and clearly identifiable official vehicles and personnel are necessary. The checkpoint should only be operated when the traffic volume allows the operation to be conducted safely.
4) Reasonable Location:
The location of roadblocks should be determined by policymaking officials rather than by officers in the field. The sites chosen should be those which will be most effective in actually stopping drunk drivers, such as roads which have a high incidence of alcohol-related accidents and arrests.
5) Time and Duration:
Law enforcement officials are expected to exercise good judgment in setting times and durations, with an eye to effectiveness of the operation, and with the safety of motorists in mind. With these considerations in effect, there are no hard and fast rules as to the timing or duration of the roadblock.
6) Indicia of Official Nature of Roadblock:
The roadblock should be established with high visibility, including warning lights, flashing lights, adequate lighting, police vehicles and the presence of uniformed officers. Not only are such factors important for safety reasons, but advance warning will reassure motorists that the stop is duly authorized, thus reducing fright or annoyance to the motorist.
7) Length and Nature of Detention:
Each motorist stopped should be detained only long enough for the officer to question the driver briefly and to look for signs of intoxication, such as alcohol on the breath, slurred speech, and glassy or bloodshot eyes. If the driver does not display signs of impairment, he or she should be permitted to drive on without further delay. If the officer does observe signs of impairment, the driver may be directed to a separate area for a roadside sobriety test. At that point, further investigation must be based on probable cause, and general principles of detention and arrest would apply.
8) Advance Publicity:
Advance publicity is important to the maintenance of a constitutionally permissible sobriety checkpoint. Publicity both reduces the intrusiveness of the stop and increases the deterrent effect of the roadblock. The thought is that advance notice limits intrusion upon the individual's personal dignity and security because those stopped would anticipate and understand what was happening. Further, advance publicity serves to establish the legitimacy of roadblocks in the minds of motorists.
The Supreme Court also stated that motorists who seek to avoid a roadblock may not be stopped and detained merely because they attempted to avoid the roadblock. However, if the motorist commits a vehicle code violation or displays obvious signs of intoxication, there is adequate probable cause to pull over the motorist, after which point general principles of detention and arrest apply.
If law enforcement does not follow the factors set out by the Supreme Court, the evidence gained as a result of the roadblock may be suppressed as an intrusion on the 4th Amendment rights of the motorist.
Roadblocks: What types of Roadblocks allowed?

What types of Roadblocks allowed?
Roadblocks have been established to be "seizures" under the Fourth Amendment. The Fourth Amendment states that a person should be free from unreasonable searches and seizures of their person and their belongings, absent individualized suspicion of wrongdoing. The touchstone for all issues under the Fourth Amendment is reasonableness. Federal constitutional principles require a showing of either the officer's reasonable suspicion that a crime has occurred or is occurring or alternatively that the seizure is carried out pursuant to a plan embodying explicit, neutral limitations on the conduct of individual officers. California constitutional principles are based on the same considerations. That is, balancing the governmental interests served against the intrusiveness of the detention. In California, in order to justify an investigative stop or detention, absent a warrant, there must be probable cause. Probable cause are those circumstances known or apparent to the officer must include specific and articulable facts causing him or her to suspect that some crime has or will take place, and the person stopped is somehow involved in that activity. Reasonableness requires that anyone in the police officer's position would have come to the same conclusion.
However, not all searches and seizures require a reasonable suspicion of criminal activity. Searches conducted as part of a regulatory scheme in furtherance of an administrative purpose, rather than as part of a criminal investigation to secure evidence of a crime, may be permissible under the Fourth Amendment, even absent a showing of probable cause. The reasonableness of an administrative screening is determined by balancing the public interest against the intrusion on the individual. It is under this philosophy, that some types of roadblocks have been determined to be legal while other types of roadblocks are not.
DUI Roadblocks
DUI roadblocks have been determined to be part of a regulatory scheme in furtherance of an administrative purpose, and not traditional criminal investigative stops. The primary purpose of a sobriety roadblock is to promote public safety by deterring intoxicated drivers from driving on public streets and highways. Therefore, if the appropriate guidelines have been followed (Ingersoll factors), DUI roadblocks are legal. Essentially, there must be a neutral screening process applicable to all motorists passing by the roadblock which limits the discretion of the officers in deciding who to stop. The intrusiveness on individual motorists must be limited. The detention of motorists is brief, encompassing only a few questions which allow the officer to observe objective signs of intoxication. In addition, officers will shine their flashlights into the vehicle in order to observe any alcoholic beverages. The Supreme Court has ruled that this intrusion on the individual is slight in comparison to the value to society in keeping drunk drivers off the road.
Drug Roadblocks
The Supreme Court holds that roadblocks whose primary purpose is to detect evidence of ordinary criminal activity are unconstitutional, and therefore illegal. Even though drugs are a scourge on society and are responsible for many of society's ills, there isn't the same vehicle-related threat to life and limb that exists with drunk driving. If law enforcement agencies were allowed to detain citizens based on any of the crimes facing society, then the constitutional protections we enjoy today would disappear. Therefore, because the primary purpose of a drug roadblock is to detect evidence of ordinary criminal wrongdoing, it is unconstitutional.
Roadblocks to find Witnesses to a Crime
The United States Supreme Court has held that an "information-seeking" roadblock, where police briefly detain motorists to pass out flyers and ask if they witnessed a crime is constitutional. Illinois v Lidster held that an Illinois roadblock did not violate the Fourth Amendment's prohibition of unreasonable searches and seizures and was constitutional. The checkpoint was reasonable because it advanced a "grave" public interest and only minimally interfered with the liberties afforded by the Fourth Amendment. The police officers in this case were investigating a crime that resulted in a human death by stopping motorists on the same stretch of road, at the same time that the accident occurred, asking motorists briefly whether they had witnessed the crime or had any information, and passed out fliers. The Supreme Court held that information-seeking roadblocks are less likely to provoke anxiety or to prove intrusive. Further, the law ordinarily allows police to seek voluntary cooperation of members of the public in the investigation of a crime. Because the crime they officers were investigating was motorist-related, and the stop itself was brief, it is constitutional.

A roadblock, also known as a sobriety checkpoint, is a temporary stop-point operated on a public road, which must be governed by established guidelines, set out by the California Supreme Court in the premiere roadblock case, Ingersoll v Palmer. A sobriety checkpoint roadblock must have advance notice to the public, set up by policymaking officials other than officers in the field, guided by a neutral mathematical formula, maintained safely for both police and motorists, have high visibility thus serving to give advance warning to the motorist as to the official nature of the stop, and minimize the average time each motorist is detained.
Each motorist stopped should be detained only long enough for the officer to question the driver briefly and to look for signs of intoxication, such as alcohol on the breath, slurred speech, and glassy or bloodshot eyes. If the driver does not display signs of impairment, he or she should be permitted to drive on without further delay. If the officer does observe signs of impairment, the driver may be directed to a separate area for a roadside sobriety test. At that point, further investigation must be based on probable cause, and general principles of detention and arrest would apply.
The United States Supreme Court has held that a vehicle stopped at a roadblock is a "seizure" under the Fourth Amendment. A Fourth Amendment seizure occurs "when there is a governmental termination of freedom of movement through means intentionally applied." The question then becomes whether such seizures are reasonable under the Fourth Amendment. It has been determined that not all roadblocks violate the Fourth Amendment right against unreasonable searches and seizures. In order to determine whether there has been a Fourth Amendment violation, courts apply a "balancing test" which balances the government's interest against the intrusiveness of the detention on the individual. If a roadblock is operated in accordance with the required safeguards set out in Ingersoll, then there is no actionable intrusion on the Fourth Amendment. The intrusion on the individual is justified by the magnitude to society of having drunk drivers on the road. The Supreme Court has stated that the primary purpose of a sobriety check point is not to discover evidence of crime or to make arrests of drunk drivers, but to promote public safety by deterring intoxicated persons from driving and endangering the public. Thus, a sobriety checkpoint roadblock serves a regulatory purpose and is not considered a criminal investigation roadblock, and no warrant is required.
