Q: What constitutes a DUI in California?
In California, a DUI, or Driving Under the Influence, is defined as operating a vehicle while impaired by alcohol or drugs. Under California Vehicle Code Section 23152(a), it is illegal for any person to drive a vehicle while affected by alcohol, drugs, or a combination of both. Furthermore, California has a specific threshold for blood alcohol concentration (BAC). If a driver’s BAC is 0.08% or higher, they are presumed to be legally intoxicated. This threshold is lower for commercial drivers, whose limit is 0.04%, and for drivers under the age of 21, where any detectable alcohol can lead to a DUI charge.
Additionally, the charge can be applied to individuals who are under the influence of any substance that affects their ability to operate a vehicle safely, including prescription medications, illegal drugs, and over-the-counter substances. The law addresses both alcohol and drugs collectively, emphasizing that impairment is the key factor rather than the specific substance consumed. A police officer may administer field sobriety tests or breath tests to assess a driver’s level of impairment on the road.
Penalties for a DUI conviction in California can be quite severe and include fines, license suspension, mandatory alcohol education programs, community service, and even jail time, depending on the circumstances and whether it is a first or repeated offense. California takes DUI offenses seriously, reflecting the intent to enhance road safety and deter impaired driving.
