A traffic stop, colloquially referred to as being pulled over, is a temporary detention of a driver of a vehicle and its occupants by police to investigate a possible crime or minor violation of law.
A traffic stop is usually considered to be a Terry stop and, as such, is a seizure by police; the standard set by the United States Supreme Court in Terry v. Ohio regarding temporary detentions requires only reasonable articulable suspicion that a crime has occurred or is about to occur. [1] Traffic stops can be initiated at any time during the detention and arrest process, ranging from stops prior to arrest or issuance of a ticket for violation based on probable cause.
Traffic stops date to the 1920s. [2] [3]
Traffic stops may be executed upon reasonable articulable suspicion that a crime has occurred, for example, an observation of a possible equipment violation or a suspicion of driving under the influence (DUI) based on driving behavior. In some jurisdictions, general roadblock checkpoints are applied for random checks of driver. A primary purpose of the traffic stop at this point is frequently to determine if the police have probable cause for arrest. At this stage, the police are not required to issue a Miranda warning, because a traffic stop prior to formal arrest is not considered to be custodial under Miranda, and will often ask questions intended to elicit the suspect to provide answers that may be used as evidence in the event of an arrest.
Non-evidentiary testing falls under this stage because implied consent laws in the US generally do not apply to Preliminary Breath Test (PBT) testing (small handheld devices, as opposed to evidential breath test devices). (For some violations, such as refusals by commercial drivers or by drivers under 21 years of age, some US jurisdictions may impose implied consent consequences for a PBT refusal,[ citation needed ] but these are generally not considered to be a refusals under the general "implied consent" laws.) [4] Participation in "field sobriety tests" (FSTs or SFSTs) is voluntary in the U.S.. [5] [6]
Probable cause is the arrest stage in which sufficient evidence is available to sustain a warrant for arrest. Probable cause is a stronger standard of evidence than a reasonable suspicion, but weaker than what is required to secure a criminal conviction. In some cases, notably DUI stops, the "sufficient evidence" is used for requiring an evidentiary chemical test (e.g., evidential breathalyzer test) by invoking an implied consent request. While state terminology regarding whether evidentiary testing is an "arrest", such testing is constitutionally a "search incident to arrest". [7]
A stop is usually accomplished through a process known as "pulling over" the suspect's vehicle. Police vehicles (except those used by undercover personnel) traditionally have sirens, loudspeakers, and lightbars that rotate or flash. These devices are used by the officer to get the attention of the suspect and to signal that they are expected to move over to the shoulder and stop. Failure to comply could result in citation of failure to yield to an emergency vehicle and possibly raise suspicion that the driver is attempting to flee.
Similar alerting devices are also typically equipped on other emergency vehicles such as fire trucks and ambulances, although police departments often use blue lights to signal drivers to pull over. In all cases, such signals and the laws requiring that other vehicles pull to the shoulder allow the emergency vehicles to pass other traffic safely and efficiently when responding to emergency situations. In the case of a traffic stop, the officer pulls the patrol vehicle behind the subject vehicle as it stops instead of proceeding past as they would during other emergency responses.
Depending upon the severity of the offense which the officer believes to have occurred, the officer may either arrest the suspect, by taking them to jail, or check for any outstanding warrants before issuing a citation also called a notice to appear or summons in some jurisdictions, which is essentially a traffic ticket. In some cases, officers may choose to simply issue a verbal or written warning.
If the driver is not the owner of the car, they are only penalized for the ticket. However, in most cases, the owner of the car that was stopped has increased insurances rates. This is due to a rule put in place to protect insurance companies from fraudulent procedures.
Many states have enacted laws requiring freeway traffic approaching the police vehicle to merge over to the left, leaving an entire lane as a buffer zone for the officer.
A "felony" or "high-risk" traffic stop occurs when police stop a vehicle which they have strong reason to believe contains a driver or passenger suspected of having committed a serious crime, especially of a nature that would lead the police to believe the suspects may be armed (such as an armed robbery, assault with a weapon, or an outstanding felony warrant for the registered owner). In a high risk stop, officers attempt to provide their own safety by issuing instructions to maintain absolute control over every step of the proceedings.
They will have additional officers on scene for back-up, often waiting for additional officers to join up before initiating the stop. They will typically have their weapons drawn, and stay back from the suspect's vehicle, using their patrol cars for cover. If there is no choice but to make the stop on a busy street, then they will often stop traffic. They will address the driver and any passengers over the PA speaker of the patrol car, typically instructing the driver to turn the engine off, remove the keys from the ignition, and sometimes toss them out the window. They will instruct the occupants, one at a time, to exit the vehicle with empty hands showing, place their hands on top of or behind their heads, walk backwards some distance, and then lie flat on the ground, where they will remain until all occupants have done likewise, at which point officers will move up, apply handcuffs, do a body search and then secure the suspects in the patrol cars. The vehicle is then typically searched for weapons and other evidence in accordance with the arresting department's standard operating procedures ("S.O.P.'s").
The Supreme Court has held that an officer who stops a vehicle as part of a routine traffic stop has the authority to order the driver to exit the vehicle, [8] as well as to order any passengers to exit the vehicle. [9]
The United States federal government has long used local traffic enforcement as a tool to further its goals through providing funding and training. Historically, this goal has been drug interdiction, but this has been expanded to include the War on Terror. [10] [11] Currently, the National Highway Traffic Safety Administration (NHTSA) in cooperation with two agencies in the United States Department of Justice (the Bureau of Justice Assistance and the National Institute of Justice) actively promote a program called Data-Driven Approaches to Crime and Traffic Safety (DDACTS) which provides training to local police forces to combine traffic enforcement with fighting crime. [12] [13] In the past, such approaches have been accused of promoting racial profiling. [14] [15]
Federal grants to states often use the number of traffic tickets as a performance measure. [3]
Several states and cities have restricted or discouraged minor traffic stops, such as for broken equipment, to avoid dangerous interactions between drivers and armed law enforcement, [16] [17] which put both police and drivers at risk [18] and lower trust in the police. [16] Nationally, 43% of traffic stops are for speeding, 24% for broken equipment, and 9% for suspected criminal activity. [19] 730 police killings from 2017 to 2022 started with traffic stops. [20] 7% of killings by police started with a traffic stop. Two thirds of killings by police started with no crime or a nonviolent crime. [21]
Jurisdictions can still use traffic cameras, [18] send tickets in the mail [22] [23] and can pull the car over and send a text message if both driver & police agency sign up for the service. [24]
75% of police have not received recent hands-on training in removing a noncompliant person from a vehicle. [19] Noncompliance was most common in cases of alcohol, drugs or illegal activity, and 42% of noncompliance involved disobeying the officer, while 24% involved not answering the officer' questions, a practice recommended by lawyers. [25] Some North Carolina cities encouraged drivers to refuse searches by requiring the officer to get a signed form, which clarified the voluntary nature of searches. [26]
Some departments have quotas for at least a minimum number of traffic stops per officer per month, [27] or supervisor pressure. [28]
Illinois in 2016 found contraband in one stop per 242. [18] In July 2021 a study found that State patrol traffic stops were not associated with reduced motor vehicle crash deaths and suggested other strategies such as motor vehicle modifications, community-based safety initiatives, improved access to health care, or prioritizing trauma care as other reduction efforts. [29] France, England and Wales use traffic stops at a quarter to a third of the US rate. [18]

Stanford has compiled data on race of drivers stopped in 200 million traffic stops. [46] Stops are particularly common and harmful for minorities. [26] California's annual report under the Racial and Identity Profiling Act (RIPA) highlights that minorities form a bigger share of traffic stops than their share of the residents in each area. [47]
Several organizations have commented that comparing minority share of traffic stops to resident population is an erroneous approach, and that there are other possible comparisons, including: driving age population, traffic accidents, licensed drivers, traffic violators, arrests, and crime suspects. [48] On average, minorities work more jobs and work from home less than non-minorities, so are on the road more than their share of the residential population. Also, police are called by people in minority neighborhoods more than elsewhere, so police are in a position to see more traffic violations there. [49] The New Mexico Sentencing Commission in 2007 called the use of Census data on residents a "common, but very poor method," and listed other methods. [50] A 2006 report from the US Department of Justice shows the different comparison groups used by studies up to that point. [48] A 2023 study for the Peace Officers Research Association of California (PORAC) listed some of the same alternative comparison groups: licensed drivers, vehicle owners, center city populations, field studies, and traffic violators. [51]
There is another way comparative reports underestimate the number of Black drivers. Typically statistics on residents call them Black only if they are not Hispanic, and are not mixed race. Mixed race and Hispanic residents are counted separately. [31] Police will count people stopped as Black even if they are also Hispanic or are also of another race. (RIPA shows that police rarely classify drivers as multi-racial. [47] ) So the comparison of traffic stops underestimates the number of Blacks in the resident population and overestimates Blacks among the people stopped.
A Connecticut investigation found that 26,000 traffic tickets reported by state police did not appear in court records. The researchers hypothesized that state police were trying to look productive. The fake stops were disproportionately white, reducing apparent racial gaps. The police union said data entry errors were the likely cause. [52]
Several police unions print cards for members to give to friends, family members, and professional contacts. Officers who make a traffic stop and are shown the card are under pressure to let the holder off with a warning instead of a ticket. [53] [54] The pressure can be from fellow officers [53] and supervisors. [54]
The cards have been issued in New York City, New Jersey, [53] Boston, [55] Los Angeles [56] and Philadelphia. [57] Cards were a "time-honored" tradition in Los Angeles by 1923 despite efforts by the police chief and a city councilman to stop them. The California Highway Patrol gave cards under Chief Cato, appointed in 1931. [56] The cards were widespread in the United States in the 1950s, including by criminals. In 1976 the New Hampshire Governor handed them out to large contributors. [56] The New York City Civilian Complaint Review Board in 2006 ruled the cards are private property and may not be confiscated without cause by police. [56]
Law firms say that showing the card, and especially then asking for lenience, can be illegal if it is considered trying to influence an officer. [58] [59]
The cards have a racial effect, since police are disproportionately white. The cards go to whites disproportionately, including as Christmas gifts, [60] leaving minorities with disproportionate tickets. The racial effect is increased when officers have quotas of tickets to issue, which then go disproportionately to minority citizens who lack a card. [54]
The cards have been used since at least 1936. [53] [61] 20-30 have been given to each police officer each year, and 10-20 to each retired officer, so they have also been available on auction sites for up to $200. [60] [53]
In the United States, traffic stops have been criticized for their use in police dragnets to check compliance with laws such as those requiring the use of seat belts or those prohibiting driving while impaired. Some people have objected that the tactic violates the United States Constitution; the Fourth Amendment to the Constitution, part of the Bill of Rights, contains a provision against unreasonable search and seizure. However, the United States Supreme Court has ruled that a motor vehicle is subject to a diminished expectation of privacy as compared to a home. Reasons include the fact that motor vehicles are typically driven on public streets, that said vehicles are generally subject to public licensing and registration requirements, and that said vehicles are generally held out to public view in a way different than that of traditional dwellings.
Drunk driving is the act of operating a motor vehicle with the operator's ability to do so impaired as a result of alcohol consumption, or with a blood alcohol level in excess of the legal limit. For drivers 21 years or older, driving with a blood alcohol concentration (BAC) of 0.08% or higher is illegal. For drivers under 21 years old, the legal limit is lower, with state limits ranging from 0.00 to 0.02. Lower BAC limits apply when operating boats, airplanes, or commercial vehicles. Among other names, the criminal offense of drunk driving may be called driving under the influence (DUI), driving while intoxicated or impaired (DWI), operating [a] vehicle under the influence of alcohol (OVI), or operating while impaired (OWI).
A traffic enforcement camera is a camera which may be mounted beside or over a road or installed in an enforcement vehicle to detect motoring offenses, including speeding, vehicles going through a red traffic light, vehicles going through a toll booth without paying, unauthorized use of a bus lane, or for recording vehicles inside a congestion charge area. It may be linked to an automated ticketing system.
Terry v. Ohio, 392 U.S. 1 (1968), was a landmark U.S. Supreme Court decision in which the court ruled that it is constitutional for American police to "stop and frisk" a person they reasonably suspect to be armed and involved in a crime. Specifically, the decision held that a police officer does not violate the Fourth Amendment to the U.S. Constitution's prohibition on unreasonable searches and seizures when questioning someone even though the officer lacks probable cause to arrest the person, so long as the police officer has a reasonable suspicion that the person has committed, is committing, or is about to commit a crime. The court also ruled that the police officer may perform a quick surface search of the person's outer clothing for weapons if they have reasonable suspicion that the person stopped is "armed and presently dangerous." This reasonable suspicion must be based on "specific and articulable facts," and not merely upon an officer's hunch.
A Terry stop in the United States allows the police to briefly detain a person based on reasonable suspicion of involvement in criminal activity. Reasonable suspicion is a lower standard than probable cause which is needed for arrest. When police stop and search a pedestrian, this is commonly known as a stop and frisk. When police stop an automobile, this is known as a traffic stop. If the police stop a motor vehicle on minor infringements in order to investigate other suspected criminal activity, this is known as a pretextual stop. Additional rules apply to stops that occur on a bus.
"Driving while black" (DWB) is a sardonic description of racial profiling of African-American motor vehicle drivers. It implies that a motorist may be stopped by a police officer largely because of racial bias rather than any apparent violation of traffic law. It is a word play of driving while intoxicated.
Reasonable suspicion is a legal standard of proof that in United States law is less than probable cause, the legal standard for arrests and warrants, but more than an "inchoate and unparticularized suspicion or 'hunch'"; it must be based on "specific and articulable facts", "taken together with rational inferences from those facts", and the suspicion must be associated with the specific individual. If police additionally have reasonable suspicion that a person so detained is armed and dangerous, they may "frisk" the person for weapons, but not for contraband like drugs. However, if the police develop probable cause during a weapons frisk, they may then conduct a full search. Reasonable suspicion is evaluated using the "reasonable person" or "reasonable officer" standard, in which said person in the same circumstances could reasonably suspect a person has been, is, or is about to be engaged in criminal activity; it depends upon the totality of circumstances, and can result from a combination of particular facts, even if each is individually innocuous.
Atwater v. Lago Vista, 532 U.S. 318 (2001), was a United States Supreme Court decision which held that a person's Fourth Amendment rights are not violated when the subject is arrested for driving without a seatbelt. The court ruled that such an arrest for a misdemeanor that is punishable only by a fine does not constitute an unreasonable seizure under the Fourth Amendment.
"Stop and identify" statutes are laws in several U.S. states that authorize police to lawfully order people whom they reasonably suspect of committing a crime to state their name. If there is not reasonable suspicion that a person has committed a crime, is committing a crime, or is about to commit a crime, the person is not required to identify himself or herself, even in these states.
A random checkpoint is a military and police tactic. In a military context, checkpoints involve the setup of a hasty roadblock by mobile truck- or armored vehicle-mounted infantry to disrupt unauthorized or unwanted movement or military activity and to check for valid identification and search for contraband, fugitives, or weapons that are not permitted in civilian hands. Random checkpoints are set up to achieve surprise, as opposed to known permanently located checkpoints, which suspects could circumvent. They are often established in locations where they cannot be observed by approaching traffic until it is too late to withdraw and escape without being observed.
Welsh v. Wisconsin, 466 U.S. 740 (1984), was a 1983 case before the US Supreme Court determining that a warrantless home arrest without exigent circumstances violates the Fourth Amendment protection against unlawful search and seizure.
United States v. Brignoni-Ponce, 422 U.S. 873 (1975), was a case in which the Supreme Court determined it was a violation of the Fourth Amendment for a roving patrol car to stop a vehicle solely on the basis of the driver appearing to be of Mexican descent. A roving patrol car must have articulable facts that allow for an officer to have a reasonable suspicion that the person is carrying illegal aliens beyond their ethnicity. The Court handed down a 9–0 decision that affirmed the Circuit Court's ruling in the case. This case was also the final case that William O. Douglas presided on, as he retired shortly after this case, ending his record 36 years as an Associate Justice.
"Contempt of cop" is law enforcement jargon in the United States for behavior by people toward law enforcement officers that the officers perceive as disrespectful or insufficiently deferential to their authority. It is a play on the phrase contempt of court, and is not an actual offense. The phrase is associated with unlawful arbitrary arrest and detention of individuals, often for expressing or exercising rights guaranteed to them by the United States Constitution. Contempt of cop is often discussed in connection to police misconduct such as use of excessive force or even police brutality as a reaction to perceived disrespectful behavior rather than for any legitimate law enforcement purpose.
Whren v. United States, 517 U.S. 806 (1996), was a unanimous United States Supreme Court decision that "declared that any traffic offense committed by a driver was a legitimate legal basis for a stop."
Arizona v. Johnson, 555 U.S. 323 (2009), is a United States Supreme Court case in which the Court held, by unanimous decision, that police may conduct a pat down search of a passenger in an automobile that has been lawfully stopped for a minor traffic violation, provided the police reasonably suspect the passenger is armed and dangerous.
Pennsylvania v. Mimms, 434 U.S. 106 (1977), is a United States Supreme Court criminal law decision holding that a police officer ordering a person out of a car following a traffic stop and conducting a pat-down to check for weapons did not violate the Fourth Amendment to the United States Constitution.
Racial profiling by law enforcement at the local, state, and federal levels, leads to discrimination against people in the African American, Native American, Asian, Pacific Islander, Latino, Arab, and Muslim communities of the United States. Examples of racial profiling are the use of race to determine which drivers to stop for minor traffic violations, or the use of race to determine which pedestrians to search for illegal contraband. Besides such disproportionate searching of African Americans and members of other minority groups, other examples of racial profiling by law enforcement in the U.S. include the Trump-era China Initiative following racial profiling against Chinese American scientists; the targeting of Hispanic and Latino Americans in the investigation of illegal immigration; and the focus on Middle Eastern and South Asians present in the country in screenings for ties to Islamic terrorism. These suspicions may be held on the basis of belief that members of a target racial group commit crimes at a higher rate than that of other racial groups.
Rodriguez v. United States, 575 U.S. 348 (2015), was a United States Supreme Court case which analyzed whether police officers may extend the length of a traffic stop to conduct a search with a trained detection dog. In a 6–3 opinion, the Court held that officers may not extend the length of a traffic stop to conduct a dog sniff unrelated to the original purpose of the stop. However, the Court remanded the case to the United States Court of Appeals for the Eighth Circuit to determine whether the officer's extension of the traffic stop was independently justified by reasonable suspicion. Some analysts have suggested that the Court's decision to limit police authority was influenced by ongoing protests in Ferguson, Missouri.
Navarette v. California, 572 U.S. 393 (2014), was a case in which the United States Supreme Court clarified when police officers may make arrests or conduct temporary detentions based on information provided by anonymous tips. In 2008, police in California received a 911 call that a pickup truck was driving recklessly along a rural highway. Officers spotted a truck matching the description provided in the 911 call and followed the truck for five minutes, but did not observe any suspicious behavior. Nevertheless, officers conducted a traffic stop and discovered 30 pounds (14 kg) of marijuana in the truck. At trial, the occupants of the car argued that the traffic stop violated the Fourth Amendment of the United States Constitution, because the tip was unreliable, and officers did not personally observe criminal activity. Writing for a majority of the Court, Justice Clarence Thomas held that the 911 call was reliable, and that officers need not personally observe criminal activity when acting upon information provided by an anonymous 911 call.
Devenpeck v. Alford, 543 U.S. 146 (2004), was a United States Supreme Court decision dealing with warrantless arrests and the Fourth Amendment. The Court ruled that even if an officer wrongly arrests a suspect for one crime, the arrest may still be "reasonable" if there is objectively probable cause to believe that the suspect is involved in a different crime.
Drug interdiction, the interruption and interception of drugs to prevent them from reaching their destination, is a tactic often used by U.S. law enforcement in the context of traffic stops. Law enforcement use pretextual traffic stops in order to stop drivers. Pretextual stops are traffic stops conducted by law enforcement for a traffic violation, but the purpose is for the officer to investigate an unrelated crime that the driver was not stopped for. A law enforcement officer can learn about a potential suspect from a traffic stop by identifying the driver, engaging in conversation with them, and conducting a visual inspection of the vehicle's interior. This is useful in drug interdiction because the officer essentially has the driver in a position where they are not allowed to leave, so the officer can use their skills in order to elicit information that may lead to an arrest. In Whren v. United States, the Supreme Court ruled that the motivation underlying a traffic stop is irrelevant as long as the officer has probable cause for the traffic violation they are stopping the driver for. When law enforcement observes a traffic violation they automatically have probable cause to stop the vehicle.
