Many individuals believe that as long as their blood alcohol concentration, or BAC, is under 0.08 percent, they are safe from DUI arrests. However, this is a common misconception. While 0.08 percent is the legal limit for alcohol intoxication in most states, including West Virginia, it is not the only factor that law enforcement officers consider when making a DUI arrest. In fact, you can still be arrested for driving under the influence even if your BAC is below this limit. This article explores the reasons why a BAC under 0.08 doesn’t guarantee that you won’t be arrested and the additional factors that could lead to an arrest for DUI.
What Does a BAC Below 0.08 Really Mean?
BAC refers to the percentage of alcohol in your bloodstream. A BAC of 0.08 percent is the legal threshold in many states, including West Virginia, for being considered legally intoxicated. However, the law doesn’t stop there. A BAC under 0.08 percent doesn’t automatically make you immune to a DUI arrest. In fact, law enforcement officers are trained to assess a driver’s level of impairment through various observations, including the driver’s behavior, coordination, and other factors beyond just the BAC reading. 
West Virginia DUI laws define impairment as the inability to drive a vehicle safely. This definition is broader than just the BAC number. A person with a BAC under 0.08 can still exhibit signs of impairment, such as poor coordination, difficulty concentrating, or delayed reaction times, which could justify an arrest.
The Role of Field Sobriety Tests in DUI Arrests
One of the main reasons a BAC under 0.08 doesn’t protect you from a DUI arrest is that law enforcement officers often use field sobriety tests to assess impairment. These tests measure your balance, coordination, and ability to follow instructions. Even if your BAC is under the legal limit, failing a field sobriety test may be enough for an officer to suspect impairment and make an arrest.
In West Virginia, as in other states, officers use a variety of field sobriety tests to determine whether a driver is under the influence of alcohol or drugs. These tests include the one-leg stand, walk-and-turn, and the horizontal gaze nystagmus test, which involves following an object with your eyes. The results of these tests are used in conjunction with the officer’s observations to make an arrest decision.

It is also important to note that some people may fail field sobriety tests due to factors unrelated to alcohol, such as fatigue, nervousness, or medical conditions. This means that even if your BAC is below 0.08, a failed sobriety test could still lead to an arrest.
Officer’s Observations Are Key to DUI Arrests
Even if your BAC is under 0.08, the officer’s observations are incredibly important. Law enforcement officers are trained to look for signs of impairment beyond a breathalyzer test. They assess how you react to questions, whether you can maintain your balance, and whether your speech is slurred. If the officer observes signs that you are impaired, such as slow reflexes, difficulty following directions, or erratic driving, they may decide to arrest you for DUI even if your BAC is below the legal limit.
In addition to physical signs of impairment, officers may also take into account any erratic driving behavior. This includes weaving between lanes, driving at inconsistent speeds, or failing to obey traffic signals. Even if your BAC is below 0.08, these behaviors can be enough to raise suspicion and result in a DUI arrest.
Harley and Heather gave me peace of mind as they walked me through the process of my DUI. Heather was so quick to answer even the smallest and probably irrelevant questions I had. I was extremely nervous to walk in the courtroom, but Harley made sure I was in and out of there in no time with the best deal I could think of. My DUI charge was reduced to a speeding ticket and some online DUI classes. Would absolutely recommend Harley and Heather if you’re ever in need of a lawyer.”

Impairment from Drugs and Medications Can Lead to Arrests
It is essential to recognize that DUI laws in West Virginia are not limited to alcohol. Drug impairment, including the use of prescription medications, over-the-counter drugs, and illegal substances, can also lead to DUI arrests. In fact, it is possible to be arrested for DUI even if your BAC is below 0.08 and no alcohol is involved.
For example, if an officer suspects that you are under the influence of marijuana or prescription drugs that impair your ability to drive, they may arrest you for DUI based on their observations and your performance on field sobriety tests. Many prescription medications, such as painkillers, antidepressants, and antihistamines, can impair motor skills and cognitive functions, making it dangerous to drive.
West Virginia has strict laws against drugged driving, and an arrest can occur even if your BAC is within legal limits but your ability to drive is impaired by drugs or medications.
Medical Conditions and Physical Factors Can Affect BAC and Impairment
Certain medical conditions and physical factors can also influence how alcohol affects your body. Some people metabolize alcohol differently, which means they may still feel impaired even with a BAC under 0.08. For instance, individuals with liver conditions or metabolic disorders may have lower tolerance to alcohol, making them more susceptible to impairment at lower BAC levels.
Furthermore, medical conditions such as vertigo, neurological disorders, or even anxiety can affect the results of field sobriety tests, making a person appear impaired even though their BAC is under the legal limit. This is why it’s important for officers to consider all factors, including medical conditions, before making an arrest decision.
