What Happens When Police Suspect Drug Use During a Traffic Stop
When a police officer pulls someone over in West Virginia and suspects drug use, it often starts with simple signs. The officer may say you were driving too slow, weaving in your lane, or making unsafe turns. These actions can raise concerns that a driver may be impaired by something, and if alcohol doesn’t seem to be the cause, the officer may start looking for drug use.
Sometimes, police notice other things that they believe point to drugs. Maybe your eyes look red, your movements are slow, or you’re talking in a strange way. Even the way you answer questions or how long it takes you to find your driver’s license can be used to claim you’re under the influence. But it’s important to remember that none of these things automatically mean someone is impaired by drugs. Fatigue, illness, or even stress can cause these signs too.
Field Sobriety Tests and What They Really Show
After pulling someone over, an officer may ask them to get out of the car and perform field sobriety tests. These are physical and mental tasks used to check balance, coordination, and attention. The tests might include walking in a straight line, standing on one foot, or following a finger with your eyes. These tests are supposed to show whether someone is under the influence of drugs or alcohol.
But these tests are not always fair or accurate. If you have a medical condition, physical disability, or are just nervous, you might struggle to do well. And in many cases, officers may decide you failed even if you did your best. Their decision is often based on what they think they see, which isn’t always clear or right. Still, what they write in their report can be used in court to support a DUI drug charge.
Drug Recognition Evaluators and Their Role
In some West Virginia DUI cases, police bring in someone called a Drug Recognition Evaluator, or DRE. These are officers trained in a special program to look for signs of drug use. They use a 12-step process that includes checking your pulse, looking at your pupils, watching how you move, and asking you questions. The DRE then gives an opinion about what kind of drug they believe you used.
But the truth is, even DRE opinions can be wrong. They are still just police officers, not doctors. Their judgment is based on what they observe, and many of the signs they rely on—like blood pressure, temperature, and behavior—can be caused by many things other than drugs. Being nervous, having a medical condition, or even being tired can affect these signs. So their opinion isn’t always strong enough to prove guilt.
Blood and Urine Tests for Drugs
Police often try to back up their decision with a chemical test. If they think you’re under the influence of drugs, they might ask you to take a blood or urine test. These tests are used to find out if any drugs are in your system. They can show whether you’ve used marijuana, painkillers, or other substances. But even if a test finds drugs, it doesn’t always mean you were impaired while driving.
That’s because some drugs can stay in your body for days or even weeks after use. Marijuana, for example, can show up in a urine test long after the effects are gone. So while the test may prove you used a drug, it doesn’t prove you were too impaired to drive at the time you were stopped. This is an important difference that your lawyer can challenge in court.
How Drug DUI Cases Are Different from Alcohol Cases
In alcohol DUI cases, police often use a breath test to show how much alcohol is in your system. If your blood alcohol content is over the legal limit of 0.08 percent, that number can be strong evidence in court. But drug DUI cases are different. There is no clear legal limit for most drugs in West Virginia. That means police have to rely on what they see and what tests show, which are not always reliable.
Because of this, defending a drug DUI case can be very different from an alcohol one. The evidence is often weaker and based more on opinion than fact. That gives you a better chance to fight the charge with the right defense strategy.
Why These Cases Can Be Fought and Won
Just because an officer says you were impaired doesn’t mean the case is over. Many people believe they can’t win once they’re charged, but that’s not true. There are many parts of a drug DUI case that can be questioned. For example, your lawyer can look at how the traffic stop happened. If the officer didn’t have a legal reason to stop you, the case might be thrown out.
Your lawyer can also challenge how the field tests were given, whether the DRE followed the rules, and whether the chemical tests were done correctly. In some cases, the drugs found in your system may not even be able to cause impairment. All of these details matter. With careful work and attention, your case can be challenged and sometimes even dismissed.
Common Defenses That Can Help You
There are many ways to defend a DUI drug case. One way is to show that your driving behavior had nothing to do with drug use. Maybe you were distracted, tired, or dealing with an emergency. Another way is to challenge the field sobriety tests. If the officer didn’t give clear instructions or made a mistake, that could weaken the case.
Your lawyer can also bring in medical records or witnesses to explain why you looked or acted a certain way. If the drug test was flawed, that can be another strong defense. And in some cases, police may have violated your rights during the stop or the testing process. All of these things can make a big difference in the result of your case.
