When Are Urine Tests Used in DUI/DWI Cases in Louisiana?

When police investigate alcohol- or drug-related criminal activity, in some circumstances, a driver may be required to submit to a urine test. Typically, a urine sample is taken in the presence of a police officer.

The urine test can detect metabolites within an individual's blood to determine if an individual was under the influence of a drug, but they do not detect the presence of a specific drug. Because urine samples provide less reliable evidence than breath and blood tests, they are rarely used, and some jurisdictions may not allow them.

In jurisdictions where this test is allowed, they are used primarily in two situations:

1. A medical condition prevents a person from providing a breath or blood sample; ;or
2. Blood or breath tests are not available for some reason.

Where the blood and breath tests are unavailable, it often means the technician, for whatever reason, is unavailable.

Urine test results can be used as evidence for both drunk driving and drugged driving-related offenses. The good news is this: the results are weaker and less reliable; therefore, they are more vulnerable to challenges.

Can You Refuse a Urine Test in Louisiana?

Like breath and blood tests, you can refuse to submit to a urine test. But also like breath and blood test refusals, there may be consequences. The police officer must advise you that a refusal can lead to consequences. Failure of the police to do so means you can challenge any consequences you face. Speaking to a North Louisiana DUI/DWI defense attorney is in your best interest so that you know what your legal options are in any given scenario.

What Constitutes a Urine Test Refusal?

Knowing what constitutes a urine test refusal is important, but it is also murky. Some jurisdictions allow you to request a different chemical test -- but only once. So, if you request a breath test, that does not (or should not) constitute a refusal.

Keep in mind also that police can be manipulative. If you say you "can't go" or otherwise have a problem providing a urine sample, the police may say you refused.

Possible Consequences of Urine Test Refusal

If you refuse a urine sample for whatever reason, you could risk:

• The police requesting a warrant to obtain a blood sample
• The state automatically suspending your driver's license
• The state imposing significant fines for the refusal

The above consequences are administrative penalties, so they are imposed even if you are not charged and subsequently convicted of any DUI/DWI offense.

If you are convicted of a drugged driving or drunk driving offense in Louisiana, you can face additional fines, license suspension, and/or jail time as a result of the urine test refusal.

Problems with Urine Tests in Louisiana

Urine tests are commonly believed to be the most unreliable of the three chemical tests used by the police.

Typical problems with urine tests include:

• Inability to provide exact type of drug
• Inability to provide exact amount of drug
• Cannot determine when a drug was consumed (could have been a week ago or an hour ago)
• Substantially providing a person's blood alcohol concentration (BAC) much higher than it is

Also, like breath and blood tests, urine samples and urine tests must be handled and conducted in accordance with strict regulations. Failure to comply with these regulations or any type of tampering or mishandling of the sample can compromise the integrity of the test results.
