Case Dismissed

Any violation of “Title 17” in the California Code of Regulations can be your ticket to dismissal of your DUI charge. The regulations in Title 17 can be quite intricate and confusing, so it’s best to consult with a seasoned DUI attorney about your case.

If there is any violation or mishandling during this procedure, a motion to suppress the evidence can be filed and the prosecutor will likely dismiss the charges.

A Title 17 violation can be the key to a successful DUI defense strategy. The results range from a complete dismissal, to a DUI plea bargain, to a not-guilty verdict if the case goes to trial.

What Is Title 17?

Title 17 of the California Code of Regulations comprises all the rules and procedures that have to be followed by police officers and crime laboratories when testing blood alcohol levels as part of a DUI investigation. There are three types of tests that can be performed:

  • a chemical blood test,
  • a breathalyzer test, or;
  • a urine test (used in case a blood sample cannot be collected).

DUI Blood Tests

A brief overview of a few key Title 17 requirements for Blood Testing in California:

  • The blood draw must be performed by an authorized technician
  • The draw site must be cleaned with an alcohol-free cleaning agent
  • A sufficient amount of anticoagulant and preservative must be placed in the blood vial (clotting or fermenting could produce high false readings of blood alcohol concentration (BAC))
  • The anticoagulant or preservative in the vial must not be expired
  • The anticoagulant and preservative must be sufficiently mixed with the sample
  • The blood sample must be properly stored

DUI Breath Tests

Rules and procedures for DUI breath tests according to Title 17:

  • The breath testing instrument must be calibrated every 10 days or 150 uses, whichever comes first
  • The breath sample must be from the deep lung air, or “alveolar air”
  • The suspect must be observed for at least 15 minutes prior to taking the sample
  • During the 15 minutes prior, the person must not eat, drink, smoke, vomit, or regurgitate

DUI Urine Tests

DUI / DUID urine test regulations according to Title 17:

  • The person submitting the urine test must first void his/her bladder and then provide a urine sample at least 20 minutes later. A sample taken any earlier is not accurate timewise.
  • The urine sample must be properly stored and retained for 1 year so that you may retest it later by yourself with a third-party laboratory if needed.

Urine tests are usually given only if a blood or breath test is unobtainable, or if the defendant is suspected of driving under the influence of drugs or a combination of drugs and alcohol.
