When Is a Breath Test Optional in CA?

Any breath tests that an officer may request before a person is arrested are 100% optional and do not need to be taken. This is known as a Preliminary Alcohol Screening (PAS) test and may be conducted by a police officer using a hand-held breath-testing unit for the purposes of determining if there is enough evidence to arrest a driver for DUI. If you are pulled over, you are not required by law to submit to a preliminary breath test, though an officer will likely not indicate this.

Submitting to a PAS breath test is only mandatory if:

  • You are under 21 years of age
  • You are on California DUI probation for a previous offense

What if I Have Already Been Arrested?

Any breath test that an officer may request after a person has been arrested is mandatory under California’s “implied consent statute.” This law states that by simply being issued a California driver’s license, you have already consented to any breath, blood, or urine test that an officer may request in the event that you are lawfully arrested for suspected DUI. Refusing to submit to a breath test after being arrested can bring various consequences.

Refusal of a post-arrest chemical test can result in the following penalties:

These penalties increase in severity depending on a person’s prior record of test refusals and DUI offenses. While those who submit to a breath test can sometimes apply for a restricted license, refusing a breath test will nullify this opportunity. In most cases, it is recommended you do not refuse a breath test, as the additional consequences will most likely not be worth potential benefit of limiting the officer’s evidence of your intoxication. If anything, refusing a breath test is often seen as a sign of guilt and can be used to the prosecution’s advantage. It is best to submit to a test and contact an attorney as soon as possible.
