DUI Zero Tolerance


“Zero tolerance” as it relates to driving under the influence of drugs or alcohol (DUI) means that certain drivers may not drive with a blood alcohol content (BAC) of 0.01 or above. Zero tolerance currently applies to two types of drivers: those under the age of 21 and those already on probation for a previous DUI.

Zero Tolerance for Probationers

On Jan 1, 2009, California Vehicle Code section 23154 was amended to require that drivers on probation submit to a preliminary alcohol screening (PAS) breathalyzer to measure their BAC. If probationers are found driving with a 0.01 BAC or above, it will be a violation of their probation, to which various penalties will attend. Currently, there are no further civil sanctions, but the Legislature may add them at a later time. Unlike someone not on probation, refusal of a probationer to submit to a PAS breathalyzer test or other field sobriety tests will result in driver’s license suspension or revocation from 1 to 3 years.

Zero Tolerance for Minors under 21

Vehicle Code section 23136 proscribes drivers under 21 from driving with a BAC of 0.01 or greater. A convicted driver under 18 will have his or her license revoked for a year or until she attains 18, whichever is greater. For example, a 16-year-old DUI convict won’t be able to drive until she turns 18. A minor between 18 and 21 will have her driver's license suspended for a year and incur additional fines at the DMV. Unlike drivers over 21, minors must submit to field sobriety tests and PAS breathalyzers, or have their license suspended for up to a year.

A minor under 21 whose BAC is from 0.01 to 0.04 will only incur license suspension, DMV fines, and other civil fines. A minor with a BAC from 0.05 to 0.08 will be subject to criminal penalties under Vehicle Code 23140, which include taking a DUI program, possible car impoundment, fines, and criminal record. A minor under 21 with a BAC of .08% or higher will be tried as an adult, and subject to misdemeanor penalties such as criminal fines, jail time, community service, DUI classes, and more.
