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:

Four Medical Conditions That Can Be Mistaken for IntoxicationIf you are stopped on suspicion of driving while intoxicated, the police officer will be looking for signs that you may be under the influence of alcohol or drugs. Besides the telltale odor of alcohol, symptoms of intoxication include slurred speech, watery eyes, and appearing disoriented. However, there are pre-existing medical conditions that may cause these same symptoms without you being intoxicated. Even a breath alcohol test can be tainted by a medical condition. An officer will likely assume that these symptoms are due to intoxication, and it may not occur to you to mention your medical condition during your stop. You need to tell your DWI defense lawyer if you have any of the following conditions:

  1. Diabetes: A person with diabetes can function normally as long as they keep their blood sugar at a stable level. If their blood sugar falls too low, they can become irritable, dizzy, and disoriented – all of which the officer could interpret as intoxication. Additionally, people with diabetes may have an abnormally high amount of ketones in their breath, which a breath test may mistake for alcohol.
  2. Brain Injury: Suffering a brain injury can cause symptoms that never fully go away. The victim may always have trouble with speaking, short-term memory, and coordination. Your friends and family may understand that this is how you normally behave, but a police officer does not know that and may conclude that you are intoxicated.
  3. Epilepsy: People with epilepsy can suffer seizures without warning. If a seizure happens while they are driving, they could get into a serious accident or be forced to pull over. A police officer who encounters someone having a seizure may see a person who is unresponsive, distracted, dizzy, or even violent. They may arrest the person on suspicion of DWI without knowing that the person is suffering a medical emergency.
  4. Dementia: Dementia is a degenerative mental condition, meaning that the symptoms will progress over time. A person in the early stages of dementia may occasionally be confused, unresponsive, or irritable. A police officer may conclude that an intoxicating substance is causing this behavior and not a mental condition.

Alcohol Sellers Can Be Culpable in DWI CasesWhen a person is accused of driving while intoxicated, they are considered responsible for becoming intoxicated and choosing to drive. A first-time DWI conviction in Texas is a Class B misdemeanor, punishable by as long as 180 days in jail, a fine of $2,000, and a driver’s license suspension. However, responsibility for a DWI sometimes extends to the person who served the alcohol to the driver. It is a crime in Texas to sell alcohol to someone who is intoxicated, and a conviction can lead to serious consequences – particularly if the intoxicated person hurts someone during their DWI incident.

Bartender Charged in Connection with DWI Case

A bartender in Austin, Texas, was recently arrested for allegedly serving alcohol to an intoxicated man who was later involved in a fatal accident. The driver was charged with intoxication manslaughter and failure to stop and render aid. The driver allegedly hit a man pushing a shopping cart and fled the scene on foot before police caught him. An investigation by the Texas Alcoholic Beverage Commission determined that a bartender at an area restaurant had served alcohol to the driver when he was noticeably intoxicated. After arresting the bartender, the Commission stated that alcohol retailers and their employees must be accountable for monitoring the physical condition of their customers and potentially preventing a DWI incident.


Selling alcohol to an intoxicated person is a misdemeanor offense and punishable by a maximum fine of $500 and up to a year in jail. However, the consequences extend beyond criminal charges. The person who sold alcohol to an intoxicated driver may be liable for personal injury damages if someone was hurt or killed in an accident. The establishment that sold the alcohol could be fined or have its liquor license suspended.

How a Background Check on Your Texas License Plate Can Lead to a DWI ArrestAn arrest for driving while intoxicated in Texas starts with the police officer having reasonable suspicion that the driver has broken the law, either while monitoring passing traffic or when responding to an accident. An officer is legally allowed to stop a driver if the driver has committed a traffic violation or is driving in a manner that suggests impairment. The officer may also conduct a background check on drivers by entering their license plate numbers into a database, which may indicate that the driver has an outstanding warrant or the vehicle is not confirmed to have liability insurance. During the stop, the officer can arrest the driver for DWI if there is probable cause to believe that the driver is intoxicated.

Precedent in Texas

A 2017 Texas appellate court ruling confirmed that a police officer is legally allowed to stop a vehicle that a database flagged for not having insurance, even if the database was inaccurate. In 2015, an officer was entering plate numbers of passing vehicles when one was listed for “unconfirmed insurance,” which could mean that the insurance on the vehicle had lapsed. He stopped the vehicle to check for proof of insurance and eventually arrested the driver on suspicion of DWI.

The defendant was convicted for the DWI charge but appealed the decision, saying that the traffic stop was not legal because his vehicle was insured at the time. Despite the inaccuracy in the database, the appellate court confirmed the conviction:

How CBD Products Can Lead to a False DWI Charge in TexasTexas passed a law in 2019 that legalized the sale and use of hemp and its derivative products. The law, in turn, has grown the market for cannabidiol (CBD) products in the state. You may have noticed signs and advertisements for products infused with CBD, such as oils, edibles, and lotions. CBD should not be confused with tetrahydrocannabinol (THC), an active ingredient in marijuana, which is still illegal in Texas except for medical use in specific cases. It is legal to drive after having consumed CBD products because it should not impair your driving ability. However, some drug testing labs in Texas admit that their equipment is unable to tell the difference between CBD and THC, which could lead to someone being wrongly charged with driving while intoxicated by marijuana.

Difference Between CBD and THC

People sometimes confuse hemp with marijuana because they both come from the cannabis plant. As the legalization of hemp shows, federal and local governments now recognize that hemp does not pose the same dangers as marijuana. One of the primary differences between hemp and marijuana is the amount of CBD and THC it has. Hemp, by legal definition, has less than 0.03 percent THC, which is not enough to impair a normal person. CBD has the same molecular structure as THC but does not have the psychoactive component that would impair someone.

DWI by Marijuana

Because marijuana is illegal in Texas, the grounds for charging someone with a DWI by marijuana is different than with alcohol:
