Choose Your Words Carefully During a DWI StopIf you have ever been pulled over by a police vehicle, you know the dread and nervousness you feel even if you do not believe you have done anything wrong. Feeling nervous can cause you to say things that you will later regret. Unfortunately, police can use what you say during a traffic stop as evidence in order to arrest you for an offense such as driving under the influence of alcohol or drugs. How can you get through a traffic stop without saying something that may be incriminating? You should know when to be quiet and how to answer questions honestly without divulging too much information.

Silence Is Golden

One way to avoid making an incriminating statement is to keep your talking to a minimum during the stop. Speak when the officer asks you a question but otherwise remain silent. Do not volunteer information that the officer did not ask for, even if you think that it may help you. For instance, saying that you are not drunk before the officer asks you a question will make them more suspicious. You do not have to prove anything. The officer is the one who must prove that there is probable cause to arrest you.

What to Say

During the stop, the police officer may ask you questions that will try to make you admit on your own that you are intoxicated. Common questions include:

Hunches Are Not Reasonable Suspicion in DWI StopsAll arrests for driving while intoxicated must start with the police officer establishing reasonable suspicion to stop a vehicle. Accepted reasons to stop a driver include traffic violations or erratic driving behavior. However, officers will sometimes stop drivers on nothing more than a hunch that they are committing a DWI offense. Traffic stops based on hunches are illegal, even if the hunch ends up being correct. Any evidence that came after that illegal stop would be suppressed in court, effectively ending the prosecution’s case. There are several ways that an officer may use a hunch instead of reasonable suspicion to initiate a DWI stop:

  1. Targeting Bar and Restaurant Patrons: Many drunk drivers became intoxicated because they were at a public establishment that serves alcohol. Police officers know that there is a greater risk of DWI incidents near bars and restaurants, but they cannot stop a driver simply because they were leaving such an establishment. The driver must show signs of impairment that create reasonable suspicion that they may be intoxicated. Stopping the driver prematurely would be targeting a driver based on a presumption of guilt.
  2. Unidentified Container: Having an open container of alcohol in a vehicle is both against the law and evidence of a possible DWI incident. However, an officer may be unable to justify a stop based solely on what they guess could be an alcoholic beverage container in the vehicle. It is difficult to identify the label or contents of a container from a distance. Non-alcoholic beverages come in many of the same cans and bottles as alcohol. The officer would need to pair their observation of a possible alcohol container in the vehicle with other evidence that creates suspicion of intoxication.
  3. Not Accounting for Adverse Driving Conditions: Intoxicated drivers can draw suspicion from police officers by driving too slowly or swerving. This behavior suggests possible impairment under normal circumstances, but adverse driving conditions can also be a reasonable explanation. For instance, there is a difference between driving slowly on a clear night and during heavy rainfall. With visibility decreased and the road slick, driving below the speed limit could be the responsible decision given the conditions. It should be a more likely explanation for the officer than suspecting that the driver is intoxicated.

What Signs Are Police Watching For During a DWI Stop?Police suspicion that you may be driving while intoxicated can start from the moment you are pulled over. Erratic driving suggests to them that you might be impaired, and the time of night and proximity to drinking establishments may further their suspicions. However, suspicions and police intuition about your driving are not enough reason to immediately demand a sobriety test or arrest you for DWI. The officer will observe your appearance and behavior to determine whether there is probable cause for an arrest.

Your Appearance

Officers are familiar with the visual cues that a driver may be under the influence of alcohol or drugs, such as:

  • Bloodshot or watery eyes;
  • Dilated pupils;
  • Flushed face;
  • Sweating;
  • An odor of alcohol or drugs; and
  • An unkempt appearance.

A combination of any of these symptoms will raise suspicion, but each one could have an explanation that is unrelated to alcohol or drugs. You may be sweating or have bloodshot eyes if you are sick or tired. While being sick or tired can impair your driving ability, the consequences are not the same as being under the influence of an intoxicating substance. The smell of alcohol or drugs is more difficult to explain. It is possible that the odor could be coming from a current or recent passenger who was drinking or using drugs.

Prosecutors Predict Increase in New Year's Weekend DWI ArrestsTexas Department of Public Safety troopers made 400 arrests for suspicion of driving while intoxicated during the Christmas and New Year’s weekends last year. Local and state law enforcement always anticipate an increase in DWI incidents during holidays, but prosecutors believe there may be even more arrests than normal because of the day of the week that New Year’s Day falls on. Having the weekend followed by New Year’s Eve on Monday and New Year’s Day on Tuesday could mean a long weekend of drinking leading up to the holiday.

How Police Prepare

Local police departments often use public information campaigns to educate people about the dangers of drunk driving and the potential consequences if you are caught. For a major holiday, they prepare for an increased number of drunk drivers by increasing their own enforcement efforts:

  • More police officers are on patrol, watching for drunk drivers on roads they are most likely to use;
  • More prosecutors are available to advise officers on whether there is probable cause to make a DWI arrest;
  • More judges are on call to issue blood warrants, which require you to submit to a blood alcohol concentration test; and
  • More nurses are available to draw blood samples to be tested.

Law enforcement sometimes sets up DWI checkpoints, where officers stop all drivers to check for signs of intoxication. However, Texas has not authorized DWI checkpoints because they subject drivers to a search without establishing reasonable suspicion of committing a crime.

Anonymous Tips Can Justify DWI StopsA police officer must have a reasonable suspicion that a driver has committed an offense in order to legally stop the driver. For cases of driving while intoxicated, the officer usually must witness driver behavior that suggests that the driver is impaired. A 2014 U.S. Supreme Court ruling set a precedent that an officer can stop a vehicle based on an anonymous tip, even if the officer does not witness the alleged behavior. If your DWI arrest stemmed from an anonymous tip, your defense can question the credibility of the tip and argue that it did not create enough reasonable suspicion to allow the officer to legally stop you. Your defense will ask several questions about the nature of the anonymous tip:

  1. How Detailed Was the Tip?: A witness providing a credible tip about a drunk driver should say more than “I saw a drunk driver.” Did the anonymous source describe why he or she thought the driver was drunk? Was the source personally affected by the driver’s behavior? Did the source sound coherent when giving the explanation? The prosecution has a heavy burden to prove the credibility of the tip because it cannot prove the source’s personal credibility.
  2. Did the Information Create a Reasonable Suspicion?: An anonymous source is likely a private citizen who is not trained to judge whether a driver may be impaired. Some driving mistakes do not reach the level of impaired driving, but the witness still reports it as suspicious activity. The witness may have seen a supposedly intoxicated person walking towards his or her car without seeing that person actually get in the vehicle and drive away.
  3. How Was the Tip Reported?: Courts find an anonymous tip to be more credible if the person giving the tip believes that he or she may not remain anonymous. A person is unlikely to make a false report by calling 911 because the operator can trace the call. However, that idea assumes that the person knows that emergency responders have caller ID. The defense will question the credibility of any witness who did not wish to identify him or herself to the police.
  4. Is There a Transcript of the Conversation?: A recorded call of the anonymous tip provides a clear record of what the witness said. The defense can analyze the recording for inconsistencies or evidence that the tip was not credible. Without a recording, the prosecution relies on the testimony of the person who received the tip. The defense can question that person’s memory of what the anonymous source said and how the person interpreted that information.
