New Jersey DWI Urine Testing

Urine tests are often used to test for illegal substances in cases of driving under the influence of drugs.

Although a urine test can give insight into a person’s drug use history, it is not accurate in determining whether that person was under the influence of drugs at the time of the traffic stop. This is why a drug recognition expert is often utilized in DWI drug cases.

Questions for the Prosecution

Just as with any form of chemical testing, there are specific protocols and procedures that must be followed when conducting a urine test. In building a defense, your attorney should ask the following questions:

  • Was the urine sample taken in a lawful manner?
  • Was the sample’s chain of custody unbroken and properly documented?
  • Were all the machines used for testing properly calibrated and maintained?
  • Were the samples handled properly to ensure there was no contamination?
  • Was the sample stored properly?
  • Was the technician properly trained and certified?

A Drug Test is Not a Conviction

It is important to remember that a urine test alone cannot prove your guilt—that decision is left up to the judge. This is why it is important to have an experienced attorney on your side who knows how to challenge the test results and hold the prosecution and crime lab staff accountable.
