New Jersey’s driving while intoxicated (DWI) law allows police and prosecutors to establish that a person was legally impaired by alcohol or drugs in a variety of ways. This includes testimony from arresting officers about a defendant’s appearance and behavior, such as an odor of alcohol, bloodshot eyes, slurred speech, and so forth. Police may ask a driver to perform one or more field sobriety tests (FSTs) in order to assess their condition and establish probable cause for an arrest. The federal government has recognized three “standard” FSTs, but New Jersey police may use other tests in DWI investigations. New Jersey courts may accept those tests as evidence, even though their reliability is highly questionable.

Standard Field Sobriety Tests

The National Highway Traffic Safety Administration (NHTSA) has established a Standardized Field Sobriety Test (SFST) battery consisting of three tests. Each test has standard instructions for police officers to deliver to drivers, as well as objective factors that indicate the possibility of impairment. At the same time, each test has serious shortcomings that make their reliability above average at best. The three tests are the “one-leg stand,” the “walk and turn,” and the horizontal gaze nystagmus (HGN).

The non-standard FSTs do not have these sorts of objective indicators. Instead, they rely to a great extent on the individual officer’s interpretation of how an individual performs. New Jersey courts may still accept non-standard FSTs as evidence, but they should not give them nearly as much weight as the SFST battery.

New Jersey’s driving while intoxicated (DWI) statute does not limit the offense to alcohol. It also includes any “narcotic, hallucinogenic or habit-producing drug” that might impair one’s ability to drive. The statute makes proving impairment by alcohol rather easier for the state by identifying a specific level of blood alcohol content (BAC)—0.08 percent or above—that creates a legal presumption of intoxication. In cases in which police suspect impairment by something other than alcohol, or in which the BAC is below the legal limit, but they still suspect intoxication of some sort, they may bring in a “drug recognition expert” (DRE) to evaluate the suspect. DREs receive training in identifying signs of impairment by various drugs, but both their methodology and the scientific validity of their evaluations remain questionable. In fact, it is junk science that is less than 50% reliable — less reliable than a flip of a coin.

Prosecutors must prove that a defendant in a DWI case was legally impaired. Proving that the defendant’s BAC was at least 0.08 percent, based on a breath, blood, or urine test, typically satisfies this requirement. This evidence is not always available, or prosecutors may allege that a defendant with BAC of less than 0.08 percent was nevertheless legally impaired. The testimony of the arresting officer might support this claim, such as if the officer witnessed slurred speech or other signs indicating intoxication. The mere fact that a driver was not operating their vehicle safely, however, is not enough for a DWI charge, since reckless driving is a distinct offense. DREs serve to provide additional support for the allegation that a driver was impaired. It is critical that the opinion of the DRE be challenged, as any opinion based on the DRE protocol is not based on scientifically validated testing.

The Los Angeles Police Department established the first DRE program in the 1970s, after numerous DWI suspects had a low BAC but still seemed impaired to police. The National Highway Traffic Safety Administration (NHTSA) later expanded the program to other states. The International Association of Chiefs of Police (IACP) has operated a nationwide program since 1989. Police officers receive training and certification through the IACP in the recognition of seven categories of drugs. New Jersey has over 400 certified DREs.

The Fourth Amendment’s prohibition on unreasonable searches and seizures applies in all New Jersey driving while intoxicated (DWI) investigations and prosecutions. Defendants can raise Fourth Amendment challenges to numerous aspects of a DWI prosecution, such as a lack of reasonable suspicion before stopping their vehicle, or a lack of probable cause to initiate a DWI investigation. In cases in which police suspect an intoxicating substance other than alcohol, they may make use of a Drug Recognition Evaluator (DRE), who has received training in identifying signs of impairment by various drugs. A lawsuit filed last year challenges the use of DREs on Fourth Amendment grounds. While the case is pending in another state, it could affect future New Jersey DWI cases.

A private organization, the International Association of Chiefs of Police (IACP), operates the system for training and certifying DREs in cooperation with the National Highway Traffic Safety Administration (NHTSA). New Jersey has more than 400 police officers participating in the program. DREs use a 12-step process to assess whether a DWI suspect is under the influence of drugs. The IACP claims that this process is supported by scientific research, although this is subject to dispute. Part of the process, for example, involves field sobriety tests that are not part of the standard battery of tests approved by the NHTSA. A variety of medical conditions, physical impairments, and other factors could influence an individual’s performance on the various tests administered by a DRE as part of the 12-step process. A DRE’s expertise, for evidentiary purposes in court, usually does not extend beyond their specific training as a DRE.

The lawsuit mentioned above, Ebner v. Cobb County, involves three plaintiffs who, according to their complaint, were arrested, subjected to forced blood draws, and held for several hours “simply because a police officer had a hunch, based on deeply flawed drug-recognition training, that they might have been smoking marijuana.” None of them were under the influence of marijuana at the time of their arrests, they claim, and toxicology tests reportedly showed no traces of marijuana or its metabolites. They were all charged with DWI, but all charges were eventually dropped.

Under the laws of the state of New Jersey, driving while intoxicated (DWI) is a motor vehicle offense rather than a criminal offense. While a DWI conviction can result in serious penalties, including the possibility of jail time, the New Jersey court system does not deal with DWI cases in the same way it handles most criminal cases. A defendant in a New Jersey DWI case, for example, does not have the right to a trial by jury as described in the Sixth Amendment to the U.S. Constitution. DWI is considered a “petty” offense, and therefore it is not covered by all of the provisions of the Bill of Rights that apply in criminal cases. Most other rights, like the Fourth Amendment’s protection against unreasonable searches and seizures and the Sixth Amendment’s right to confront one’s accuser, still apply in DWI cases. Understanding which courts may consider DWI prosecutions and appeals, and how they are allowed to consider them, is important when planning a defense against DWI charges.

Municipal courts have original jurisdiction over DWI cases under Rule 7:1 of the New Jersey Rules of Court (NJROC). The municipal court judge handles all pretrial motions and other matters, and presides over the trial if one occurs. The judge will render a verdict and decide on a sentence. Several levels of appeal are available after a conviction in municipal court. If a person seeks post-conviction relief, however, NJROC 7:10-2 requires them to file a petition in the municipal court where the conviction took place.

Appeals from a municipal court conviction go to the Superior Court, Law Division. NJROC 3:23 requires a defendant to file a notice of appeal within 20 days of their conviction. The Law Division, upon receiving a transcript from the municipal court, may reverse the conviction and remand the case to the lower court, or it may conduct a trial de novo. While the Law Division is not bound by the municipal court’s findings of law or fact, it must “give due…regard to the opportunity of the [municipal court] to judge the credibility of the witnesses,” according to the New Jersey Supreme Court 1964 ruling in State v. Johnson.

In cases involving alleged driving while intoxicated (DWI) in New Jersey, prosecutors must prove all of the elements of the offense beyond a reasonable doubt. The New Jersey DWI statute states that a person commits an offense when they operate a vehicle “while under the influence” of drugs or alcohol. Prosecutors can prove this through testimony, such as by having the arresting officer testify about their observations of the defendant’s appearance or behavior, or through the defendant’s performance on field sobriety tests (FSTs). New Jersey evidence rules govern the ways prosecutors may introduce evidence of defendants’ performance on these tests at trial.

Accepted Field Sobriety TestsThe National Highway Traffic Safety Administration (NHTSA) has created standard procedures for three FSTs. New Jersey courts accept the use of two of the three tests in DWI investigations: the “One Leg Stand” and the “Walk and Turn”. HGN has not been held relaible to measure or check for intoxication, since there are 40 or more other causes of nystagmus in addition to intoxication.

– The “walk and turn” test involves taking nine heel-to-toe steps along a straight line, and then turning and taking nine heel-to-toe steps along the same line, back to the starting point. Officers look for whether the person maintains their balance, stays on the line, and maintains heel-to-toe contact.

Under the laws of New Jersey, driving while intoxicated (DWI) is a motor vehicle offense, rather than a criminal offense. A DWI proceeding still resembles a criminal case in many ways. Just as in a criminal case, prosecutors have the burden of proving every element of the offense of DWI beyond a reasonable doubt. DWI trials in New Jersey take place in municipal courts, with the municipal judge hearing the evidence and reaching a verdict. Prosecutors can introduce various forms of evidence, including certain actions and statements by a defendant that indicate a “consciousness of guilt.” Evidence that a defendant believed themselves to be guilty is not enough, by itself, for a conviction, but it can provide strong support for the state’s case. New Jersey courts have developed a series of rules regarding consciousness of guilt in criminal cases in general, and in DWI cases in particular.

Many criminal statutes include a particular mental state, known as mens rea, or “guilty mind,” as an element of the offense that the state must prove. Perhaps the most well-known example is the legal difference between murder and manslaughter. The offense of murder requires proof that a defendant acted with intent, meaning that they intended to kill their victim. Manslaughter involves reckless or negligent conduct by a defendant that results in someone’s death. Evidence of “consciousness of guilt” can support the state’s theory about a defendant’s “guilty mind.” The New Jersey Supreme Court reviewed some types of evidence of consciousness of guilt in a 1993 ruling, State v. Mann. Fleeing or escaping from custody for the purpose of “avoid[ing] accusation [and]…prosecution,” the court held, could be evidence of consciousness of guilt.

The New Jersey DWI statute’s definition of the offense makes no mention of mens rea. The state does not have to prove that a defendant intended to commit DWI, or even that they knew that they were impaired. Municipal judges may still infer consciousness of guilt from certain acts by DWI defendants. State law requires DWI suspects to provide breath samples to police, and it treats refusal as a distinct offense. In certain circumstances, refusal to submit to breath testing could also serve as evidence of consciousness of guilt. The New Jersey Appellate Division ruled that a defendant’s refusal was admissible as evidence in a DWI trial in State v. Tabisz in 1974. The New Jersey Supreme Court further affirmed this in 1987 in State v. Stever.

The state has the burden of proving guilt beyond a reasonable doubt in New Jersey driving while intoxicated (DWI) cases. A defense attorney’s job, in part, is to identify defects or deficiencies in the state’s case. DWI cases often require a considerable amount of documentation. Under the DWI statute, a person is guilty of DWI if they operate a vehicle while under the influence of alcohol or drugs, or while their blood alcohol concentration (BAC) is at least 0.08 percent. Police can determine BAC by testing samples of breath, blood, or urine. Breath testing is most common, followed by blood. Each type of testing requires proof that police followed specific procedures. The evidence must meet standards set by the New Jersey Rules of Evidence (NJRE), state law, and court decisions.

Authentication of Documents

In a courtroom, BAC evidence generally takes the form of written reports. In the case of breath testing, this is usually a series of reports generated by the Alcotest device. BAC results obtained from blood samples involve reports from the laboratory that performed the test. NJRE 901 requires authentication of all documents offered as evidence, meaning evidence that the document is, in fact, what the party offering it claims it is. This can be accomplished by having the person who created the document authenticate it in sworn testimony. Some documents are “self-authenticating,” as described by NJRE 902.

In any prosecution for driving while intoxicated (DWI) in New Jersey, the burden of proof is on the state to establish the defendant’s guilt beyond a reasonable doubt. When a DWI case goes to trial, every piece of evidence introduced by both parties must be approved and admitted by the judge. The evidence must comply with the New Jersey Rules of Evidence (NJRE). Testimony is often a critical part of the state’s evidence in DWI cases, such as an arresting officer testifying about their observations of a defendant and establishing their reasons for suspecting them of DWI. Understanding which testimony is allowed under the NJRE is crucial to defending against a DWI charge.

Elements of a New Jersey DWI Case

New Jersey’s DWI statute allows prosecutors to meet their burden by proving impairment by alcohol or drugs, or by proving a blood alcohol concentration (BAC) of at least 0.08 percent. Proving impairment without BAC evidence requires testimony from police officers who witnessed the defendant in whichever circumstances led to the DWI charge. Even with BAC evidence, prosecutors must introduce testimony that justifies the arrest and authenticates the BAC test results.

New Jersey laws dealing with driving while intoxicated (DWI) are consistent throughout the state, meaning that prosecutors in each county in New Jersey must meet the same burden of proof to obtain a conviction. A review of municipalities around the state by NJ.com, however, has found that some local police departments are much more assertive in enforcing these laws. New Jersey law allows municipalities to regulate the sale of alcoholic beverages, including by prohibiting their sale within city limits. These “dry towns,” according to the NJ.com report, have some of the highest DWI arrest rates in the state. Differences in arrest rates can have many possible causes, including prioritization by local law enforcement.

A person commits the offense of DWI if they operate a motor vehicle while impaired by alcohol or drugs, or while they have a blood alcohol concentration (BAC) of 0.08 percent or higher. Police and prosecutors often prefer to prove impairment with BAC evidence, since a BAC above the “legal limit” of 0.08 percent creates a presumption of intoxication. They can also meet their burden of proof with evidence of how a driver behaved, appeared, or smelled at the time police pulled them over. During patrols, police may look for vehicles that are moving erratically, which could indicate impairment by a driver. Police are also allowed to operate roadside checkpoints for the purpose of checking motorists for common signs of intoxication. Each police department has wide leeway in setting enforcement priorities.

Businesses that serve or sell alcohol must have a license to do so. New Jersey law gives municipalities the authority to determine how many licenses, if any, to issue. A municipality might ban the sale of alcohol altogether, or it might prohibit retail sales while allowing restaurants to serve alcohol. New Jersey has 32 dry towns that prohibit alcohol sales to some extent. Most of these are located in the southern part of the state. Camden County is home to four dry towns:  Audubon Park, Collingswood, Haddon Heights, and Haddonfield.

In order to convict someone of driving while intoxicated (DWI), New Jersey prosecutors must prove beyond a reasonable doubt that the person was impaired by alcohol or drugs. State law allows police to collect breath samples to test blood alcohol concentration (BAC) in suspected DWI cases. Police in New Jersey typically use a device known as an Alcotest, which analyzes breath samples provided by blowing into a tube. These devices require careful maintenance and calibration in order to produce reliable measurements. In October 2017, prosecutors in several New Jersey counties notified thousands of individuals with DWI convictions or pending charges that police may have mishandled BAC evidence in their cases. A specially appointed judge will determine whether any New Jersey DWI cases should be reviewed in light of this alleged misconduct.

New Jersey law creates an incentive for prosecutors to rely on BAC evidence. They can prove that a defendant was legally impaired through circumstantial evidence, such as an arresting officer’s testimony about a DWI defendant’s behavior and appearance. New Jersey’s DWI statute creates a presumption of impairment, however, when a defendant’s blood alcohol concentration (BAC) was 0.08 percent or higher at the time of, or within several hours of, their arrest. Penalties are also higher for first-time DWI convictions if the defendant’s BAC was 0.10 percent or greater.

The Alcotest device purports to measure the concentration of alcohol in a person’s blood by performing tests on samples of that person’s breath. This requires a certain amount of extrapolation using algorithms in the device’s programming. The device uses infrared technology and the process of electrochemical oxidation to test breath samples. This latter process is particularly sensitive to environmental factors like temperature and potential contaminants. The New Jersey Supreme Court’s 2008 decision in State v. Chun, in which we represented several appellants, established guidelines for the maintenance and calibration of these devices, as well as documentation to indicate when an Alcotest device was most recently serviced.
