Controlled Substance DWI

It’s common for people to associate driving while intoxicated (DWI) solely with alcohol. Texas law would, however, disagree with you. You could be charged with DWI for driving impaired on a controlled substance since the effects are similar to inebriation. A controlled substance can still lead to a high blood-alcohol concentration (BAC) like alcohol. The majority of controlled substances inhibit your motor controls and can affect your driving. Even driving after taking some prescription drugs can lead to a DWI. If you or someone you know has been charged with DWI involving drugs, it’s imperatnive you contact an experienced criminal defense attorney.

Are Drugs Included in DWI Laws in Texas?

Driving while intoxicated (DWI) is a serious charge under Texas law. Many believe it only incorporates alcoholic beverages, but the truth is you could be charged for driving under the influence of drugs as well. The Texas Penal Code § 49.04 states you’re committing DWI if you:

• Drive a motor vehicle on public roads; and
• Your blood-alcohol concentration (BAC) is at or above .08 OR your physical and mental faculties are impaired by alcohol or a controlled substance

It’s much easier to detect a person is inebriated from alcohol. Law enforcement use chemical tests to measure BAC and field sobriety tests to assess your physical and mental faculties. With drugs, it can get a little more complicated.

DWI Drug Testing in Houston, Texas

Police officers will often default to urine or blood analysis if they suspect drug-impaired driving. Urinalysis will identify drugs through a urine sample. However, the process is by no means perfect. Urine test results often bring up substances you used days or weeks ago because they’re still in your system. For example, you could have marijuana in your system for up to two weeks even if you’re not a heavy user. The metabolites and other chemicals will still remain in your body days or even weeks after you consumed the drug. You could be charged with DWI because the drugs you used days ago appeared on you results. A blood draw is the most accurate test when it comes to drug use. Even then, it still has problems. Lab technicians could make human errors which could lead to a false positive. In some cases, the equipment used at the crime lab is outdated and your results can come back incorrect. A common question for attorney is if you should submit to DWI testing. Most attorneys would answer no, you shouldn’t comply with DWI testing. Law enforcement can detect drugs in your system through urine or blood analysis. Additionally, submitting to chemical testing will increase your chances of reducing or dismissing your charges. The prosecution heavily relies on DWI testing results to make a conviction. A refusal will make their job difficult because they will have to rely on circumstantial and objective evidence. Because of this, it’s highly advised you refuse DWI testing.

• Administer a breathalyzer test;
• Examine their eye-tracking with exercises and compelling questions;
• Evaluate their eyes with the Horizontal Gaze Nystagmus (HGN0, the Lack of Convergence (LOC) and the Vertical Gaze Nystagmus (VGN);

• Assess their pupil size with a penlight and pupilometer;
• Evaluating their muscle tone;
